Hand Clap Sound problem

I've been chasing a problem on my build with the HC on my version 1.0 pcb. The core issue is the hand clap don't seem to be utilizing the white noise in the envelopes and sounds like a bass/snare triggered. It sounded wrong but passed the scope checks until I got to the last step U22, pin 8. Scope image looks nothing like the example.

First, I've had to modify the noise circuit per service note 5 to get a adjustable range and got that set to 130mV.

What I've done so far:
I've pulled and checked Q69-Q73 and double checked all the HC parts etc.. I've pulled U22 and other than a volume difference there was little change. I've also went through the board and checked traces from Q69-Q73 up to u22. When pulling u21 the clap sounds almost normal. I've swapped both U22 and U21 with spare IC's here in my stashes so it's not a chip problem.

I've poked arround with the scope and see what looks like a proper envelope incoming to U22.

Just looking for some pointers in help figuring this out..

Hi,

I have my Yocto working , everything is fine exept for the clap .... i programmed a clap sequence ... the first claps has no reverb ,
after the 3rd clap i have reverb but the reverb sounds a little too long.

I have searched the forum but i'm losing track ....

Is there a way to reduce the reverb length

Grtzzz,

Danny.
