I have several folders with about 1000 samples in that I want max to randomly pick and play from. I dont want to use Sfplay/sflist because it would take a long time to make the lists (even worse if I renamed the files 1.wav, 2.wav etc) - is there a way to do this - just tell max to randomly grab and play .wavs from a folder ?

randomly-playing-samples-within-a-folder

this construct can help you set up a coll with all your filenames:

..at least it should point you in the right direction?


Polybuffer~ is made for this, you can use it with info~ to populate your list and then just re-assign your playback object (whatever one you choose, as long as it's buffer~ based) for each file. I'm doing it in a patch at the moment and it works a treat.


I'd avoid umenu for this... dunno, I wouldn't want to load up a UI object with 1000 sample names.


Thanks for this, it was really useful for me . I used the patch from Chris Rolfe. I was able to sync a folder to play the files randomly . I now have an issue that it I cannot select a different folder pathway using the same patch. any ideas on why this would happen and how I can access other folder paths?

I am using a tempo-synced phasor ramp generator inside of an FFT. The reason for using FFT is because it's part of a greater patch, where the ramp down happens spectrally and can be offset per harmonic. Before I was using non-signal counter to modulate it, whilst it didn't sync as well, there was no issue. Is it possible to fix it with how I have it set up now?

Is it possible to fix it with how I have it set up now?

my first guess is 'no', because phasor~ is attempting to stay synced to the Global Transport and this falls outside the realm of the signal-vector of your pfft~, so the two will often be slightly out-of-sync unless you find a way to hard-sync the phasor~ with the bin-index of fftin~(i don't understand why: but i do get less ringing when i set my signal-vector within 'Audio Options' of Max to 64 or 128... maybe having the outer signal-vector size fall within the range of half your FFT-size helps somehow? ...but i can still hear it's a bit imprecise).
but i feel like there maybe some tricks people could come up with using sah~ to sample-and-hold the incoming phasor~, or possibly reset the phasor~ using a signal at certain times synced with that bin-index outlet... (i just don't have time to come up with all these guesses for you, and i also don't know what the larger patch does nor the longer-term goal here, so it's probably better i give you this guess and you will end up learning more by searching stuff out on your own related to this...)

since you're working with direct real/imaginary values(what you've created is more efficient than the equivalent using cartopol~ to translate real/imaginary into amplitude/phase ...and working with 'phase' is where you could use the phasewrap~ object to wrap within -π and π as mentioned in your other thread, but i'm not sure this is actually what you're trying to do, anyways -> it's more useful when you're trying to detect/rework specific parts of the frequency spectrum separate from magnitude/amplitude, but in your patch, it seems you're only reworking the overall magnitude by multiplying both real/imaginary by the (inversed)output of phasor~), i recommend going over these more too, particularly the first one:
https://cycling74.com/tutorials/the-phase-vocoder-%E2%80%93-part-i 
https://cycling74.com/tutorials/the-phase-vocoder-part-ii 

my best guess: it IS possible, but it's actually both the fft-size and hop-size(defaults to 2) which will make this difficult to sync ideally to a phasor~ which is already synced to the global transport(instead of to something within the pfft~... the signal-vector size within a pfft~ is dependent on your FFT-size, outside the pfft~ it can be different). you just need to study more closely how these parameters interweave within the overall system in order to work it around what you're trying to achieve.

also, you've probably seen this already, but just in case, there's this series that starts with more basics but still very helpful for folks of all levels of understanding, i still have to review it often:
https://cycling74.com/tutorials/advanced-max-ffts-part-7 

Alright, thanks for the ideas I will have a read of those tutorials and hopefully I will understand a bit more about what you mean. Cheers

Hello! I'm trying to make just a simple single oscillator to run on a juce plugin using the C++ export function.

Here's the repo: https://github.com/pedrononino/RNBO-OSC

In FL Studio the sound is really buggy and choppy.

REAPER it sound constant but very distorted and there are some specific frequencies where it enters some kind of resonance and the volume booms.

In Max its sounding a little distorted but its the most consistent of them all.

 is on the root folder of the repo if someone could test in other DAWs.

I've tested now using other RNBO patch (EQ) and the https://github.com/Cycling74/rnbo.example.juce template and its still distorted on FL Studio. 

Tried changing the sample rate to 44100 and 48000. Nothing happened

I've also tested changing the audio device to ASIO4ALL v2, FL Studio ASIO and primary sound device and it's still very distorted

Buggy sound on FL Studio and REAPER

I want to make a simple synced counter that goes from 0 - 1, so I can use it to modulate the volume of sounds. But it sounds ever so slightly out of time. In the screenshot you can see little gaps at the start, they are all slightly different sizes of gaps as well which is not good. How can I make it perfectly start on the bar every time?

synced-phasor~-counter-not-perfectly-in-sync

Pretty much don't use max-objects in msp and keep everyting in the msp-realm


Ty LUVULONGTIME, I need to convert the signal to a float number because its for an FFT effect, is it still possible to keep it in sync but not as a signal?

No, don't think so* but i'm not convinced you'd even actually need the float? I mean if it's for FFT can't you just keep it within MSP? 


*anytime you get something from MSP you'll get desynchronization because of the way Max and MSP are structured under the hood. Look it up here:
https://docs.cycling74.com/max8/tutorials/03_msphowmspworks


 <Edit> The example above is better because the phasor~ steps through the phase of cycle~ without any Max-object and outputs the value as a float without being (directly) in the signal-chain

Unfortunately i have to keep it as a float because i am sending it to a multislider, which some special effects are being applied to, and then all multislider vals are being put into the fft. 

Would a synced counter that doesnt use a phasor be able to be synced perfectly? If so what would that look like?

"Unfortunately i have to keep it as a float because i am sending it to a multislider, which some special effects are being applied to, and then all multislider vals are being put into the fft."

Ok, my take on this would be to store the values coming from cycle~ in a buffer and perform your effects on this instead and you connect the buffer to the fft. You can do all of this inside MSP if you really need the UI-aspect of the multislider . Have a look at the patch


Hmm okay I am starting to understand. Thanks for the help, I'll try implement this into my project tomorrow

Better use this patch instead as i cleaned it up a bit, no need for a second phasor. You can also drive it from the main one as well to keep everything in sync. And keep in mind that the resolution of multislider is set to 100 which means you have the same value for every 480 samples. Multislider has a max of 4096 so you'll have to figure out a way to make up for those other values if you need a higher resolution.

Okay cheers, luckily i only need 256 sliders :) 

I took the essence of your idea with the peek~ index~ and buffer~ and figured something out. I now have a bit of random preringing problems but other than that it works pretty great so thanks! There is just one feature I dont know how to add if i'm using an audio ramp, I have a feature that rotates the multislider to create a sort of phaserish sound spectrally. But how would I constantly rotate it using the audio ramp?

inside an fft you would use things like piwrap or count~ or the fft index inlet.

for the phasor~ object you can do phase offset like this:

[phasor~]
[+ 0.4]
[%~ 1.]


Could you explain the piwrap / count / index inlet idea a bit more I'm not sure i understand and could only see an fft index outlet on the fftin~ object 

here's a patch that can help you further understand the inner working of pfft~, it uses the old-school capture~ object to help you see the exact bin-count and you can feel free to stick capture~ anywhere else if you need to understand exactly what's going on within a pfft~(very useful to understand how 'magnitude' can differ from 'amplitude' and how 'phase' will wrap between pi and -pi, etc...), just don't leave capture~ in your final patcher, it can still drain cpu unnecessarily:

(^if you save that on your desktop as 'pfftest.maxpat' then you can just create a quick patch in Max like so 👇...

...and then just double-click on the pfft~ to open it up and double-click on capture~ within to see the signal values right there within the context of the pfft~ voice)

This is just to explain one way to synchronize different things to the bin-index outlet of fftin~ and help you snoop how things work within better(see count~ helpfile under the 'signal' tab and that can explain how you can use count~ as well, but the phase-vocoder tutorial i linked you to in the other thread also shows a usage of count~ as well).

something I've been wondering for a while. 

In regards to using the [panel] to facilitate UIs,

How much is too much before the behavior is affected. 

The scheduler has to redraw each [panel] everytime. So basically behavior accuracy decreases. right.

Over time I have gotten into the habit of using UI objects a least as possible.

Again, when I get into really big patches I want to save on CPU scheduler etc... as much as possible . So how demanding is the [panel] object.

Should I try avoiding them as I have w. other UI.

simple-panel-question

you are not saying what you are doing, i assume you change the
color of [panel] and/or resize it.

the main CPU hog here is probably not only the panel drawing 
itself, but the other parts of your patches - for example the
use of messageboxes (bad!) or numberboxes (bad!) to store 
values for you panel.

i dont know offhand if [lcd] or a pictureslider would be more 
efficient as i dont know your patch.


>>you are not saying what you are doing, i assume you change the
color of [panel] and/or resize it.

It is not for a specific patch, just every patch in general. 

In my patches, I use it as a light square colored shade  behind patch module that have a specific function. 

But as you said, UIs take away the juice and since my patches do quite a lot I want to use as little UI objects as possible. 

So yesterday while building a patch , I was wondering how heavy panels were. 

Does color change anything on CPU? I mean for the computer it's just values. White 1. 1. 1.  Black 0. 0. 0. 

But the fact that it has something more to draw every cycle,

That's all I wanted to know and thanks for the link

thats true, but in max many things - [panel] for example - 
have to be calculated by the CPU, an not by the graphics 
card, like in some jitteer objects or your favorite ego shooter.

so in fact the computer has to handle "1. 1. 1." for every pixel, 
in a panel of 1000*1000 pixels that makes a million times 
"1. 1. 1." - around 10 mb of data have to be written to a 
register and then read again in order to send them to the 
video card.

in some situations things only have to be calculated when 
they are "seen", in some situations things run completely 
on the graphics card. but for [panel] you can be sure your 
PC have to handle each byte of it.
and while it is busy with sending "1." to panel via numberbox 
and messagebox no other process (like playing a note in max,
but also like displaying html in safari) can be done.

If I understand what your saying correctly, then there is no difference between black and white. The computer has to write value. 

Again, i only use these for background purposes. 

Hi Phil.
As stated before, I wouldn't worry too much with static panels, really (even though I would instead use [bgcolor] for that matter).

what is wrong with using messages to store values?

it is probably abstraction collecting input of that object on the right

I have no idea what it should do internaly,
but you can try to replace it with accum 0.

(set float attribute to enable float processing.)

Ja, I tried accum 0. but didn't react as in the video. Something different is going on there since "mf_accum"  output values seem to reset obove 1. Would have to recreate patch im Max 6 but needs OS 10.11. - so no chance for me. video link: http://www.richardsides.com/work/vector.html

post that patch, I have max from version 3 to 8 all ready to run.
I can't recognise what that slider does really.
Values jump up and down, without real relation to slider
going positive or negative.



I thought you have old patch which can't load in max 8,
and offered to look inside for you.
Why don't you mail to Richard Sides and ask what is inside ?

 
it could be some kind of random generator,
and that slider affects output in some way.

No, sorry. The patch in the video is an old Mark Fell patch. Maybe you can quickly check in your Max 6 what the 'mf_accum' does. Thx

there is no max external named mf_accum.
that must be abstraction.


Thanks for checking it out! Sure you're right. I was hoping that it was a Max 5 or 6 external that is missing in newer versions.  Many thanks for your time! Best, P.

Hey! I'm relatively new to programming in max, and I'm having a lot of issues with the line object. I've seen on other forum posts that it's useful for a slew between signals, so I've been using it to slew between random values. I also wanted it to have a variable slew time, so I did some stuff with messages to be able to change that with a parameter. The only issue is that on lower slew times (0 - 50-ish milliseconds) i'm getting a lot of values that just go to zero for whatever reason. help would be appreciated! Here's an attached screen recording i took in case my explanation here wasn't sufficient: https://www.youtube.com/watch?v=XLqQrIKe1h4

having-a-lot-of-trouble-with-line-object-and-values-being-dropped

taking a quick guess:
you're using 'line' - this is driven by an event-rate scheduler
i think you want to look into reworking your patch using the signal-accurate version: 'line~'
also, take a look at the 'curve~' object if you want line~ but with curvature to the slew
(if you reduce the timing to 0.1, that's in milliseconds, that means not 1 millisecond, but 1/10 of a millisecond, at 48000kHz sample-rate, that would mean 4.8 samples in length of duration, an event-rate scheduler would not be efficient for this(you'd have to set it into 'Overdrive' and 'In Audio Interrupt' and then set the signal-vector to 1 sample, and then you'd have a serious CPU drain... not worth it even if this were possible), so you get the 0s at the end of the ramp automatically because that's the value the event-rate scheduler catches at the frequency it polls for event-rate values)

how-to-distribute-incoming-individual-midi-notes-to-different-midi-channels-by-order-they-are-triggered

Can you be a little more specific about your aims? Do you simply want to send each successive midi message to the next midi channel in a cycle, do you want to send each message type to a separate channel, or do you want to send all messages that arrive between one note and the next to go the same channel as the leading note? Or something else?

Hey Andy - thank you so much for reading my post and checking if you can help!
I want to send each successive MIDI message to the next MIDI channel in a cycle. I think this is what I mean, english is not my main language.

So if I trigger any note on my MIDI controller (with all continuous MIDI channel information connected to that note) and the controller decides it will assign the note to MIDI channel 6, then I want to be able to say to the note that "no, you were first in line, so I will place you in MIDI channel 1" with all the information connected to the note.
The deciding factor should be the which notes are pressed first in a ascending order 1-16.

.Event/movement 2
If i have released the note that was placed on MIDI channel 6 internally on the controller, and activate the same note again, it might assign itself to another MIDI channel or again to MIDI channel 6. Regardless of what channel it assigns itself to, this should in MAX now be moved to MIDI channel 2.

If i triggered multiple notes - all notes should be able to play simultaneously.

If this was just more confusing, I apologize. 😁 
This may not be the right way to explain MIDI, but I hope it explains what I'm trying to achieve.

if you loose relation note number - note channel
you will be in trouble.
Unless you ignore note off messages and use makenote instead.

then all other channel messages - pitch bend ?
aftertouch ?
polypressure ?
etc

If you know midi, then you know it travels as train composition
Status byte, data
taken this input:
144 46 100   145 48 120   208 66   224 0 100   129 48 30   160 46 100
what should your midi output look like  ?

1- note On 46 100 > out chan1
2- note On 48 120 > out chan2
3- aftertouch > out chan ?
4- pitchbend > out chan ?
5- note off 46 > out chan ?
6- polypressure key 46 > out chan ?
-----
this can work only if you use only note & polypressure, and ignore all other channel messages.
than make pitch -  channel reservations for each held note.

all other channel messages could be routed to ?
maybe send to all channels ?



I see in your screenshot that you are using a Linnstrument. This device can already work in MPE mode and does everything you ask for, except the channel order which is kinda random in MPE. 

In case you don’t know how to set the Linnstrument to MPE: 
Manual, section "Getting Started" and look near the end of paragraph 2 for the line "If you have an MPE synth ..."

You just need to find a method in Max that remaps the incoming Linnstrument channels to the order you want. 

Maybe your real question is 
"How to re-map incoming MPE channels to the order of arrival" ?

Source Audio, thank you for your reply, though I am not sure if I got my needs presented well enough. My MIDI output should look like an ordinary MIDI output. I've routed it through IAC-driver.

Thank you for your reply Peter, yes that is probably a good way to phrase my question "How to re-map incoming MPE channels to the order of arrival?".  I will change the topic name.:) 
About MPE, yes the channel order is usually random, though Roger Linn with his Linnstrument has in fact made the MIDI channel selection behavior in ascending order. This is a "feature" I use in my digital instrument. With new controllers like the Osmose, and Erae coming out, I've been wanting to make those controllers also behave this way (MIDI channel selection).

"You just need to find a method in Max that remaps the incoming <midi controllers> channels to the order you want." - Yes! You are absolutely right, though it was harder for me to figure out than I expected.

So currently I am stuck is at the distribution process itself. I am working on linking the number of input, which goes 1-16 and round robin, to the MIDI channel of the incoming note and send the information further so it selects that information and send it along. 
It would be great if [midiselect]'s @ch attribute had the possibility of being changed with an incoming message. Please let me know if this actually should work, and I could have just been doing it wrong.

there are many diffrent ways how you could map MPE to custom channel round robin mechanisms, so it is hard to suggest an ideal way.

but i dont see how you could find out if some y-axis value from the third key you pressed on the osmosis belongs to the third note, unless you treat the MPE data as MPE data.

if i am not mistaken you want to build a synth in max and control it by the linnstrument via MPE. so why not use MPE style messages in max and directly send it in your poly~?

i.e. use [mpeparse], not midiparse, and you should have those outlets you are looking for.

of course the MPE design sucks a bit, but i guess it is doable to do [ - 1] to  the MPE channels to end up with a proper 1-15 counting.


and... https://www.rogerlinndesign.com/support/support-linnstrument-what-is-mpe 

Maybe something like this gives you an idea:

The input comes from a Roli Seaboard (MPE). I  disassemble the midievent message and when the 4th byte (voice number) changes I replace it by the next value of a 2-16 counter. Then I put the message together again.

Of course you can set the counter to 1-16, I just chose 2-16 to test the result with a software MPE synth. I  still do not understand how this MPE thing keeps track of  voice numbers. But the synth plays fine, although I expected my rude intervention to destroy the system.

I don’t know what you are going to do with an MPE event, but the channels are set according to your request :-)


SORRY, THIS DOES NOT WORK.  
SEE SOURCE AUDIO’S EXPLANATION BELOW.

>> I  still do not understand how this MPE thing keeps track of  voice numbers.

everything is simply sent with the respective channel. i.e. the controller has to take care of that.

I searched several times for how the controller does this and found no information. But today, overnight, I understand it. MPE controllers have all sensors on each key. They could have introduced additional MIDI events like Poly Pitchbend and Poly Slide, but that wouldn't be compatible with anything. That's why the channel shuffling.

A simple system, I'm just sometimes a bit slow ... :-)

@Lars Kristian Lia
Here is another version:

SORRY, THIS DOES NOT WORK. 
SEE SOURCE AUDIO’S EXPLANATION BELOW.

this does not work.
you should expect that holding 2 keys and pressing
them to create per note aftertouch shoul keep that aftertouch linked
to THAT 2 keys.
but it will trigger the counter to cycle...

Oops.
You are right. Have not tested it properly.
This may need dynamical mapping. I don’t know how to do that.
