What do you think of the following code for replicating a 1st order all pass filter?

I get an unstable result and gen patch stops working. My gain is limited to values between 0 and 1

The allpass section is the lowest part of this gen patch.

I never implemented such a filter until now. I know there's allpass block but I want to implement this in gen together with the other two blocks you see in the patch (a lowpass and a delay line)

– Pasted Max Patch, click to retract. –

Copy all of the following text.Then, in Max, select New From Clipboard.

Here's a simple 1st order all-pass filter in Gen.

(code must be pasted into a [gen~] object)

Feedback and feedforward values generally shouldn't reach 1 or 0 or you will blow up the dac. Setting limits around 0.97-0.98 will get you to the edge of dac explosion. (remember to send the reset message to your [gen~] patch if it blows up)

How do you connect it? Second input is for that? Where do parameter values go?
