Again, replying to myself...
I just finished checking all parts in the High Tom/high Conga section. All parts check out right. I reflowed all the solder joints -- unfortunately I still get the 16th notes playing, even though, no notes for high tom are programmed in the pattern.
What could be causing this?
thanks for any help!
wow! it works! on first try! but... [SOLVED]
Dear Misa,
Clap problem: I think Q28 or Q29 doesn't work properly . Try to replace first Q28 then Q29 if it isn't working.
Tom problem: Same problem try to change Q56 first then Q57.

Thanks vincent. So I guess I fried them while soldering?
I'll order some new ones and try that, then will get back to you with feedback..

Hi Vincent,
indeed, measuring them, two of the four are most certainly broken.
I ordered some new transistors and will put them in when I get them, then let you know..
As so often before: thanks a lot for your support!

Hi Vincent,
you were right, I must have fried two transistors. replacing Q28 and Q56 did the trick!
Handclap and High Tom (thus: the whole machine is!) are working fine now.
I was able to finish the build and I am happily grooving along...!
Thanks for the excellent support!
