I forgot to say- I had to add a 12k resistor to the pot on the Crash to eliminate the noise at the high end of the pot.

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!!
