If you are wondering how you can do either 4 point interpolation or 8 point interpolation linearly, here are some gen patches I made to do it :)

Let me know if you make any improvements, would love to learn more about codebox.

Do we have a section somewhere in the gen~ documentation that discusses using arguments that enable the creation of structures that allow the use of #0 and/or -- arguments to create local references, similarly to using the mentioned arguments for e.g. local send/receive connections?

Let's say I have an abstraction, in it a buffer~ object, which is also referenced by the code placed in gen~ (in the same abstraction). I use "--#0_something" in the name in buffer~ (to behave like a "locally" named object from both MaxMSP and M4L). Now how do we translate this into a "link" to buffer~ inside gen~.

I will be grateful for your suggestions and tips.

I created a Gen~ patch that just contains a Codebox and inlets and outlets. I created it giving it a name as parameter and I can see a gendsp file was created.  I'm able to use it in new patches but for some reason in either the original patch where I created it or in new patches I'm now unable to edit it (I want to ad some nodes).  I can open it and see the contents but editing is disabled everywhere. I can probably just copy and paste the code into a new editable one, but I'm curious to know why is editing disabled. Is this a bug or am I missing something? I'm using Max 8.6.2 on Windows 11.

For example how jit.gen has the ability to lookup other pixels than the one being processed with [nearestpix]. I don't think that's possible other than re-routing the output back in with a feedback loop and re-arrange the index outside? Correct? 

Would it be possible to have this functionality within MC.Gen~? I think it would be a massive convenience from a control standpoint and also allow for (if i'm not mistaken) something i can only describe as "2d-filtering" or a "filtermesh"? 

<edit> and also btw. can we have reserved keywords for the send/receive combo so i can send "there" but receive "here"? Sending "here" or receiving "there" just doesn't sound the same...

I am trying to create a readable wavetable within gen~ using the data object 

since I need the patch to work for Oopsy daisy, the patch cannot refer to any external buffers in max

The closest answer I was able to get was this post:

https://forum.electro-smith.com/t/oopsy-wavetable-synth-without-reading-from-sd-card/3736

--using the codebox object to manually input sample values of waveforms into the data object 

The OP's patch (basic waveform oscillator) works, but when trying to add new waveforms to the patch, I ran into issues: 

I obtained sample values (256 samples) of the single-cycle waveforms from 

https://www.adventurekid.se/akrt/waveforms/

 and input those values into the codebox, I received the following errors

I double checked and the list of values I put in indeed contained 256 items, so I am confused about why it "exceeded the maximum of 256"...and then I checked the amount of items in the lists that OP put in, and they actually contained less than 256 values (250&248 respectively)...so I just deleted the last few values from my list....the error disappeared but still there is something wrong:

It seems like it's reading the new waveform I put in twice as fast as it should????

I am very new to all this and not sure if I am doing something wrong here,  or if there is any other ways of creating a wavetable completely within gen~ 

*"Datawavetable" contains OP's waveform, "datawavetable2" contains the waveform I tried to put in

I've tried to reduce a problem I'm encountering to a minimal case. The code below, when entered in a codebox

myfunc(a, b, c, d) {
	if (a > 0) {
		a = a - 1;
	}
	if (a <= 0) {
		c = mstosamps(d);
		a = b;
	}
	return a, c;
}

Param bar(4,min=1);
History foo(0);
History baz(0);
foo, baz = myfunc(foo, bar, baz, in1);
out1 = baz;

is being compiled into this, not equivalent code, in the "C" panel on the right:

myfunc(a, b, c, d) {
	if(b > 0) {
		b = b - 1;
	}
	if(b <= 0) {
		c = mstosamps(d);
		b = b;
	}
	return b, c;
}

Param bar(4, min=1);
History foo(0);
History baz(0);
foo, baz = myfunc(foo, bar, baz, in1);
expr_1 = baz;
out1 = expr_1;

Note in particular the replacement of variable "a" with "b" in the generated code.

I'll also say that I've been running into gen~ problems in...well...general. Like a lack of error messages of any kind, but code output that is basically just "expr_1 = in1; out1 = expr_1;" until I correct the error by changing the code around.

Many thanks for pointing out where I'm going wrong or helping to track down a bug.

Hi guys, I'm very new to this type of coding although am fairly proficient in Max/MSP.

I've been trying to add a feedback(per bin) control to the Spectral Delay example shipped with Gen.

I've tried messing about inside the Gen patcher with 'The Garden Of Earthly Delays' tutorial as my inspiration using [mix] and [history] objects but implementing feedback in this way in the frequency domain is causing me problems, (ie. this way it's feedback across all bins. also I get audio driver overloads due to not knowing what values to clip and fold between in the frequency domain - folding -1 1 seems to weaken the signal significantly).

Could anyone give me some tips on implementing this?

I think the Spectral Delay is a very interesting effect but is just a little bland to my ears without feedback.

spectral-delay-example-trying-to-add-feedback

check out the paper "Spectral Delays with Frequency Domain Processing" by Kim Boyle. I'm not sure if it deals with feedback though...

Also check out the patch (its not mine)...

The patch is without the feedback but I guess that in the same way that it reads delay times for bins from buffer, it could also read feedback information...


Here's one way to do feedback. I added another parameter buffer for the feedback coefficients, like the delay and amplitude buffers. Inside the gen~ you can see I took the output of the amplitude delay, scaled it by this coefficient (per bin according to the frame index), and used a [delay 2048] to act as a kind of 'history' object in the pfft~ world. Because this is a feedback loop, there will be a minimum delay time of one FFT frame in the feedback loop. A bit more fancy patching could compensate for that perhaps. I've mixed this back in before the amplitude scaling ('pre-fader'), but it could be mixed in post-fader if preferred, perhaps with a separate feedback amplitude parameter.


Once again, I forgot about the sub-patcher. Try this:


Ooh, thank you so much, sounds fantastic.


another options is to simply have a feedback loop outside the fft. (i am aware of the
limits it has, but it is ok for most situations.)


More fun can be had by adding a little offset to the delay time in the feedback path, so that it feeds back into a different bin. Swooshy.

Don't think I've seen this one yet recreated in max. This synthesis technique is quite fun because it allows you to split the FM signal into 4 components :

IThis mean that you can process, mix or spatialise each component differently.

I followed the csound code from the article quite faithfully + I recreated Sean Costello's hilbert implementation so you might even have fun using it for a bode freqshifter later

Am having an issue with gen~ and was wondering if someone could help out. 

Situation is that within a patcher abstraction I am trying to maintain a dynamic buffer name with the use of #0. Even though this already works for the buffer itself, I run into errors when including operations via gen~. The buffer itself is still referenceable from within the gen~ object, though I am not able to dynamically reference it in objects like dim or poke (as [dim #0] or [poke #0]).

Attached a simplified version of the issue.

Is there a way around this while remaining the operations in gen~?

lhello, for my m4l patch i'd like the user to choose between different distortion algorithms, each coded in gen~. i use the "gen" message to load the algorithm so the user can choose. 

i'm thinking this is a good way to save cpu load. however, does anybody know if loading gen patch dynamically can create issues in ableton  ? can it produce any kind of instability/crash ? 

another quick question with gen~, i assume that using params instead of input will also save some cpu, as params doesn't use signal ?
