I'm 99% done my current project, but having issues with porting over one portion of my logic from Max to RNBO. I'd like to play multiple notes at once with the notes be based on chord formulas (e.g. pressing c will play cmin9). To test, I've just taken the note number from notein, and added 3 to it to make sure I'm hearing it correctly, but I still only hear one note.

Anyone know the best way to play multiple notes at once in this context? I think I'll try something like uzi in the mean time, but it would be better to have a solution that plays the notes simultaneously instead of in rapid succession.

will be great if someone reply’s with a better way..,

I’m exporting RNBO to external mc.
then targeting each channel with a different note. 

the cool thing about doing it this way- you can target other aspects of individual notes - your glide, filters etc

you need as many "synth" voices as notes in the chord.
means all that stuff above which creates sound.
you need note number in, note list out,
then mtof and all the rest per list item.
rest, like velocity, volume etc can be common.

take care when unpacking notes list,
use list funnel and route.


you might look into using a subpatcher for your voices and let the subpatcher manage polyphony..

router your chord generator produced midi notes into:

@Alex Norman thanks, I think I'm close. This doesn't seem to be returning anything, however. Are the objects correct, and I've just ordered them incorrectly, perhaps?

I want to code a polyphonic multisampler in RNBO. I entend to have 6 voices of polyphony and 1 audio file per key/note (C, C#, D and so on). So basically around 80 audio files per preset.

So far, my first idea was to work with buffer~ and multibuffer~ but it seems to be a bad idea because:
- that would mean 80 or more buffers. 

- it would be quite complex to make them read another 80 .wav every time I change the preset.

Is there some other object that would work and be more practical to upload new .wav everytime I change of preset?

BTW, I added polyphony to the RNBO patch, no problem. But then I thought that it would be stupid that every voice has to load the 80 buffers so I reduced polyphony to 0, put the buffers in the top patch and made a subpatch containing the multibuffer~ and added polyphony. At this point, the multibuffer doesn't read the buffer (in the top patch) anymore. Do you know why?

Hi,
I want to code a polyphonic multisampler in RNBO. 

creating-a-polyphonic-multisampler-are-buffer-and-multibuffer-the-best-option

I'm not 100% sure why multibuffer doesn't work in a subpatcher but it looks like changing buffers isn't exactly a thing that you'd want to do per note, there is some allocation that happens as a result of changing the index in multibuffer.

It seems like there should be a better approach but, you could render a single sound file with all your samples in it (per preset), and then simply use offsets to get to the spot that you care about?

I'm trying to follow the LDR tutorial  and should have everything setup correctly, except when trying to run the Python script it can't seem to find liblo. pyliblo3 is definitely installed (when trying to install again, I get "requirement already satisfied: pyliblo3 in ./.local/lib/python3.9/site-packages (0.13.0)"), but when running the script I get:

Traceback (most recent call last):
File "RNBOPi_LDR.py", line 2, in <module>
import liblo as OSC
ImportError: No module named liblo

I'm probably missing something obvious, but would appreciate any help in troubleshooting.

under which user is you script running? have you tried to run is as sudo? maybe it's a permission issue...

another thing could be, if you are executing your script not  from command line but an IDE like Thonny or PyCharm the IDE might create their own virtual python environment and the liblo package has to be installed or linked there as well.

Hi Jan, thank you for the leads. I am trying to run it in the command line as the admin account (so same error when trying as sudo).

I am not in front of a computer right now, so unfortunately  I can't  check other things. I had trouble installing liblo on my dev machine (macOS) but on the raspberry all when well so far. I guess you already tried to purge and reinstall liblo, maybe something when wrong during installation....

@cycling74: it would be a nice detail to ship the next RNBO/RasPi bistro with liblo already on board. There are probably many of us who are using python scripts to interact with the runner.  

Today I tried to install pyliblo3 on a new RaspPi and after a long time fiddling around I gave up.It seems definitely broken. I switched to another python OSC library that seems to work fine.

I have some Max patches that make extensive use of buffir~ that I need to rebuild using RNBO. I'm not finding any direct equivalent to buffir~ in the RNBO docs, any suggestions?

I've been using the rnbo.example.juce project for my plugin for months.
In an earlier version of Max the GUI would update when parameters in RNBO would have their values change programmatically without user input. RNBO would generate a new parameter value, and it would be reflected in the JUCE GUI. Great.
In the current Max version I noticed that's not happening. Parameter changes from within RNBO are not reflected in the JUCE GUI until the plugin instance window is closed and opened again. The parameter change is not updated in the DAW host either.

I spent a whole day trying to debug C++ code for the JUCE example, only to find that rolling back the Max version and exporting and rebuilding fixed it. Perhaps it's a problem with updateSliderForParam

So this seems like an unintended change if not a bug! I'll be using version 8.5.4 in the meantime!

The latest version of RNBO attempts to fix some issues with automation that previous plugin exports have. We've changed the default for a parameter notifications and added metadata to allow for altering those defaults: https://github.com/Cycling74/rnbo.adapter.juce/blob/dd233609adc495828fa9efcf756ab2a155a3bd1d/RNBO_JuceAudioProcessor.cpp#L144C5-L148 

I believe you should get your old behavior if you define RNBO_JUCE_PARAM_DEFAULT_NOTIFY in your build process.

Here is some more information about the metadata: https://rnbo.cycling74.com/learn/using-the-vst-audiounit-target 

Well, that's pretty cool! I missed the memo :) 
I just added the metadata to the parameter I needed and I'm good to go, thank you!

edit: But now presets don't recall until the window is reopened... well, more to do.

As the plugin is no longer recalling save states or presets properly, I would like to follow your advice and "define RNBO_JUCE_PARAM_DEFAULT_NOTIFY in your build process."  I haven't figured out how to make that work yet. I tried putting "set(RNBO_JUCE_PARAM_DEFAULT_NOTIFY TRUE)" in the CMakeLists.txt file, but that's not working... Any tips?

In the meantime I've added the metadata to each object individually, but with this global change, was there any other change I should know about that would allow saves and presets to be recalled?

Here is an example compile definition:

What you did only sets a definition within the cmake build setup, it doesn't actually become a `#define`

add_compile_definitions(JUCE_VST3_EMULATE_MIDI_CC_WITH_PARAMETERS=0 RNBO_JUCE_PARAM_DEFAULT_NOTIFY)

I'm curious to know how presets behave after you do this. There is something going on with presets in the latest rnbo code that I haven't quite figured out yet, I'd like to know if you're still having issues after this or not.

Thanks! I've implemented that as above, which works as expected which is great!

EDIT: I had to delete and rebuild builds and exports, but it's all working as expected now.

Yeah, re-exporting the source code is expected, some of the codegen/interface likely changed between your previous rnbo version and the latest.

I'm happy to hear that this new setup is working for you. So, presets work okay too?


BTW, this thread was a good reminder that I hadn't actually merged the juce template develop back into main for this release.

I have a cmake cache variable already set up to do all this there now: https://github.com/Cycling74/rnbo.example.juce/blob/299823760bdd28f2f73d525479844b2b306b4bd7/CMakeLists.txt#L26

So, for future readers, you can simply change the value of that instead of augmenting the build as suggested above.


Yes, presets seem to be working as expected, thanks again Alex!

So there are no other changes in the latest juce template I should look out for? Any straightforward way to get a buffer from RNBO to JUCE for analysis GUI? I know there's a workaround that's still slightly over my head. That's the next step for me.

Happy to hear that this is all working for you!

I don't think there are significant differences in the template.. you're probably good with what you have.

RE buffer output, I'd start a new thread with that topic and see if anyone has something to say about it?

rolling back Max to 8.5.4 resolved an issue with JUCE not seeing RNBO parameter updates.

Hi all, I'm using the RNBO JUCE template to build a simple stereo echo. Once built, the VST is categorized in Reaper as a VSTi. It should be a VST effect, not an instrument. I'm wondering if there's a way to specify this somewhere in the C++ code.

As a side question, I'm suspecting that there's a functional difference between VST and VSTi. My echo has a wet/dry mix. In Reaper, when set to 100%, I'm still hearing the dry signal. When testing in Max, 100% wet totally blocks the dry signal. Can anyone confirm that this is the expected behavior for VSTi? I'm hoping that if I can specify my build as a VST effect that the 100% wet mix will function correctly.

rnbo-building-vst-effect-vs-vsti

i dont know offhand where, but yes, instrument or effect it is an attribute of VST plug-ins.

i think it is called IsInstrument (just like the message for the call in the max object) and you should find it under PlugInCharacteristics in JUCE.

the main difference is where they show up in some hosts and that instruments did not support audio-in (at least that was true for VST 2.x)

i have hacked most instruments in classic MacOS the other way round back in the days; to make them show up as effects - so that i can open more instruments than the host program suggested. it is a single byte you have to change, so you can also do it later in the build (if you know where to look)

regarding audio through options, every host handles that different. many DAWs for example have special send effects slots, while vst~ in max is of course always an insert effect.

if you implement a custom send effects routine in max, the "pass audio when plug-in is turned off" option of vst~ does no longer make any sense.


Thanks Roman! I'm looking at PluginCharacteristics now and everything is unchecked (including "Plugin is a synth"). Additionally, under Plugin VST3 Category "Fx" is selected. Searching through the generated code, I see many instances of IsInstrument = false. So, I'm still perplexed.

RNBO building VST effect vs VSTi

Hello, I'm looking to report the latency of my VST3 that I made with RNBO to the DAW. I max4live I was using thispatcher and setting the latency there. Is there any way to do this in RNBO? Ideally I'd like to be able to set it dynamically so I can adjust the amount of lookahead and have the latency compensated for. Any ideas or pointers in the right direction would be very very helpful!

Hello, I'm looking to report the latency of my VST3 that I made with RNBO to the DAW. 

latency-compensation-lookahead-rnbo

https://cycling74.com/forums/reporting-plugin-delay-to-daw-for-compensation

i would always leave it fixed at the maximum and use a sampledelay to "extend" the latency to this fixed value. you never know what a pre 3.6 host does.

Shit so I have to export to code, implement it manually and then compile? I'll give that a try and report back (will probably take me a long time haha)
I don't think I can do the "extend" trick unfortunately afaik... but I'll think about it some more, maybe it will work for me.
What do you mean by "pre 3.6". Vst3.6? Or...?

i vaguely remember that there were hosts which have problems with dynamic latency values.

in theory the plug-in can propagate what and when it wants, but don´t you think it i easier to set things to a fixed value? 

mind you, there are also hosts like this "max" which does not have latency compensation at all. a fixed latency of 500ms no matter the FIR size or lookahead parameter will make life easier for those. ;)

Fair point, I generally wouldn't want to exclude anyone just cause of the daw they use. Then again, for some users, being able to get the minimum latency is probably important and since the plugin is geared towards these kind of "detail focused" artists I still think dynamic latency might still be the best choice. Also it's not a particularly innovative idea so I'm sure there are lots of alternatives. I'll think about making a static latency version maybe.

Any thoughts on the other things I asked? I had a look at JUCE the other day and just the thought of having to dig through docs and stuff in a framework I'm not familiar with had me stressing out.
Also what do you mean by pre 3.6?

Hi gang!

First if all: huge compliments for RNBO~... I'm still very much a newbie at the time of writing but I already managed to build, and use, a very crude VST3 plugin and... it's just amazing. See: I use both Live (suite) & FL Studio side by side and while I have M4l in Live I always fantasized about what might happen if you could use Max with DAW's like 'FLS'. Now I can!

Question... everything works as expected but I'm wondering if it would be possible to 'overrule' the cloud compiler and instead use a locally set up compiler & framework? Or is this approach fully hardcoded into RNBO?
 
Note: I'm not necessarily asking how it can be done, merely if...


(edit): Thanks for the feedback!  I overlooked that option and I can easily imagine that this will make it much easier for people to filter stuff. Not gonna respond because we don't need a "ping", so... figured I'd just edit.

Hi gang!

First if all: huge compliments for RNBO~... 

would-it-be-possible-to-use-a-local-compiler-for-vst3-targets

So, yah, in hindsight this was a bit of an obvious question I suppose... 

First things first: the export sidebar features 2 options for "Source code" where the 1st option is C++ source code export. That's an obvious approach.

Second... having already experimented with VST exports (and being very impressed with it) you'll quickly learn that VST builds are powered by Juce; a "framework for audio applications and plug-in development". Best part is obvious: it can be downloaded and used for free, which is something that Cycling '74 is doing.

And there's my answer. Of course I still need a compiler for all this, but that's something which Visual Studio can handle for me.

Thanks for answering you own questions so that others with the same question can have a quick hint on what to to.
Instead of editing the title als ‚(solved)‘ there is a resolved tag you can give to the topic instead. ;)
