I can't seem to record anything with poke using phase index mode without getting ring mod sounding results. Anyone have an example patch that works?

I tried bunch of things, most recently phasor-history-one pole filter and poke inside of gen, and that inside of an upsampled poly. I really hoped something simple like rampsmooth might cut it:)

I suppose the end goal is just an oversampled buffer to overdub at different speeds or directions. Similar to a teenage engineering kind of thing, tape deck

I can't get this to work, what's wrong with my implementation? It doesn´t sound right.

https://thewolfsound.com/allpass-based-bandstop-and-bandpass-filters/#allpass-based-bandpass-filter

CalcFreq(hz, Q)
{
	bw = hz/Q;
	omega = tan(pi*bw/samplerate);
	c = (omega-1)/(omega+1);
	d = -cos(twopi*hz/samplerate);
	return c, d;
}

History hist_a(0);
History hist_b(0);


c, d = CalcFreq(100, 3);

input = in1;

feedback = (input+((hist_a*(-d*(1-c)))+(hist_b*c)));
feedforward = (feedback*(-c))+((hist_a*(d*(1-c)))+(hist_b));

final = (-feedforward+in1)*0.5;

out1 = final;

hist_a = fixdenorm(feedback);
hist_b = fixdenorm(hist_a);

I cant crack this one. There isnt much in the documentation. ChatGPT cant figure it out.  Its been posted on elswhere here, but i couldnt follow it. Basically, can i set contents for a data object and call them inside a code box. I dont really know the syntax to call a data object, as seen below. I dotn really have a patch to upload.

Hi, I have a project where I need to make a custom panner to route audio between a large number of outputs. I'd like to do this in the Gen~ codebox object for the sake of flexibility and simplicity. 

Is there a way to route audio conditionally to a large number of outputs using a for loop in the codebox? Something like this:

for (let i = 0; i < 64; i++) {
  out[i] = in1 * vol[i];
}

Trying to avoid something like having to type out out1, out2, out3, etc...

As a bonus, is there any way to make the output of a gen or a codebox a multichannel (mc) patch cable? If not these outputs will be going directly into an mc.pack object with 64 patch cables, extra manual labor I'd like to avoid if possible.

Hi, I'm using gen codebox on a project for the first time, trying to figure out the syntax. 

I'm getting an error saying a variable hasn't been declared that I have clearly declared just a few lines prior. What is causing this?

Here is a screenshot of my error which states:

if (reset == 1) {
    reset = 0;
    x = 3;
    y = 3;
    xdir = 1; //xdir clearly declared here 
    ydir = 0;
    len = 1;
    step = 0;
    change = 0;

    // Initialize the array with a spiral pattern
    for (i = 0; i < 64; i += 1) {
        poke(out_list, x + (y * 8), i + 1);
        x += xdir; //says xdir is not declared

xdir is very clearly defined as a variable just a few lines prior. Why is this happening?

Data out_val(64);
Data out_list(64);

History reset(1);



amp = floor(in1 * 64);

if (reset == 1) {
    reset = 0;
    x = 3;
    y = 3;
    xdir = 1;
    ydir = 0;
    len = 1;
    step = 0;
    change = 0;

    // Initialize the array with a spiral pattern
    for (i = 0; i < 64; i += 1) {
        poke(out_list, x + (y * 8), i + 1);
        x += xdir;
        y += ydir;
        step += 1;
        if (step == len) {
            change += 1;
            if ((change % 2) == 0) {
                len += 1;
            }
            step = 0;
            if (xdir == 1) {
                xdir = 0;
                ydir = 1;
            } else if (ydir == 1) {
                xdir = -1;
                ydir = 0;

                ydir = 0;
            }
        }
    }

[Max/MSP] This magical process in gen~

Total noob at filter design here, but I wanted to take a crack at building a phase disperser using allpass filters. This design is based on a 

 where the creator used Ableton's Phaser-Flanger stock device to do the same thing, and I just really liked the sound it had. I tried other methods of dispersion in Max but couldn't get that sound until I pulled up the gen~ biquad example and chained them together. This gets very close to the sound in the Ableton method.

The downside is that it's currently eating up over 60% of my CPU, which is a no-go for running this effect inside some of my other intensive patches (and it's not even as deep as Ableton's, which can run up to 42 stages, whereas this is only at 16 currently). Just coming here to ask if there's anything I can do to make this effect less costly, or if there's another way I might build it which gives the same sound.

Hi - i am relatively new to Max8 / MSP / gen~ and generally its coming along fine but there is this thing bugging me - itsa question concerning the [ scale 1 0 0 1 -1 ] operator within the abstraction go.unit.trapezoid.gendsp

on page 68 of the amazing book "Generating Sound & Organizing Time" -

by what calculation does the fifth argument (-1) in [scale 1 0 0 1 -1 ] accomplish its task here?

i understand the function of the [scale] operator - and i am familiar with the maths and graphs of exponential curves - it is just i cannot grasp how this (-1)  affects the offset [phasor] slope the way it does when it enters the following [ * ] operator .

will be grateful for a kind explanation -

Maybe I've been spoiled by the usual max signal world taking care of sample rates so I can play a sound file at the correct pitch regardless of the sample rate. 

I don't seem to be able to get gen~ to do this. Does the following patch display the expected behaviour?  I could't find anything about it in the documentation.
