CGS09 question

2007-02-19 by Jan-Ahrent Czmok

hi all,

thanks for the help regarding CGS37 (this is now working beautifully)
i have upcoming questions to CGS09:

My design has those pots ( see comments behind if my assumption re:
cabling is correct)

- POT labeled Divide --> no idea about wiring ? to CMP ???
- CLOCK IN jack. -> to M+ pad
- CV IN jack -> to DIV pad
- PULSE OUT jack -> to HO pad
- TRIG OUT jack -> no idea ???
- UP jack -> STUP
- DOWN jack -> STDN

I might redesign another frontpanel, so i surely include the LA/LK
(LED) and the LO (LFO out ?)

What else to include in the redesign ? Am i right regarding the pads ?

DIVIDE Pot --> 100K Division pot on schematic
CLOCK In jack --> M+In pad
CV IN jack --> to 1K pullup and 100K Division pot, as in schematic
PULSE OUT jack --> LO Pad
TRIG OUT jack --> HO Pad
UP jack --> UP pad
DOWN jack --> DN pad

Thanks, that seems to work, however, when i have the following setup:

- Q119-sequencer gate out -> multiple
- multiple to ADSR1 then VCA
- multiple to CLOCK IN,
- PULSE OUT to ADSR2 then VCA

both VCA's are feeded with the same signal (sinewave) and mixed into
a audio mixer.

if i assume right, with the pot total left (e.g. against ground)
there should be no
"delay" difference between both pulses on the VCA, but there is a
noticeable
(e.g. 1 to 5 times slower) delay when pot is total left.

CV is not fed, normalized against according diagram.

Any more hints what could still be wrong ?
