Thanks for the info. I've got them working now, and have also decided
to take a different route with it as well. I built three of them,
each with different cap/resistor values. 1) .1 uF & 1K 2) .2 uF & 2.2
Kohm 3) 2 uF & 10Kohm. All use 100 Kohm pots, BTW.

I'm putting them in a breakout box with some other stuff, including a
midi controlled bit scrambler patch bay (thanks to highly liquid for a
great kit on that one). I soldered wires to Pins 64, 62 and 60 on the
gate array (64 and 60 picked to make soldering easier, since spilling
over onto adjacent pins wont effect anything, gives you a little elbow
room), and those route out to the breakout box. I'm going to use 3 SP
4-position rotaries mounted next to the pitch pots to target the 555s
to each clock, each having an off position, and one or maybe two
toggles that will allow the "stock" clocks to be shorted to each
other. Sounds crazy to have all of those clocks stacked on top of
each other, up to 6. Haven't been able to fully experiment, but I was
stacking several clocks and then engaging scrambles and it did finally
crash on me.

Got the cymbal/hat decay mods going last night, that's a great mod. I
opted out of using the "floor" resistors on the pots, which gives a
nice mute effect at the extreme which I like a lot. BTW, I had a
problem with the solder pads, lost both of them on R173. I was able
to determine from the schematics what it connected to, so I just
tinned the pot wires and soldered them to the relevant solder blobs on
the bottom of the board, so no big deal at all, but that is something
to be aware of if you plan on doing this.

Anyway, thanks for all the info, this is a great resource, glad to
contribute something to it finally (though small perhaps).
