Hello Swekompatibel-

I just finished the pitch mods, as well as Decay for the CH, OH, Crash, & Ride, and they all came out great. I made 10 555 oscillators, the last 2 for Crash and Ride. I attatched the ride to pin 10 on IC23. The Crash goes to pin 10 on IC18. (Note: I did not unattatch these pins from the board because when I tried it like that the sound was all scratchy and distorted.)

To power the other 8, I used the +5V pin 28 on IC35 and grounded it to pin 14 on the same IC. I hope this helps

MAX

So, I am about to do this mod to my 707. But i have some questions.

Where should i connect the last one of the nine 555 osc
Eight goes to 56, 57, and 59-64 of ic30, but where goes the ninth 555
osc (the ride/crash)

The out and ground on the 555 osc goes to the pins (56, 57, and 59-64
of ic30) and the ground in the tr-707.
But where should i connect the +5V on the 555 osc to a powersupply in
the tr707

Thanks for the help!!
