hi all,
i've built a cem3310 EG according to the datasheet specs. i just
have buffered pots hooked up to give 0/+5 and 0/-5v, for the ADSR voltage
inputs.
my question: it all works fine except i'm getting the "q1 disabled
(see hints)" waveform for the output, which basically jumps from 0 to the
sustain voltage and then releases. (no A/D stages)
anyonw know how to fix this? pin 16 is "attack out", which is
configured as logic output for the attack, but in all the schematics i've
seen, it's tied directly into the - output of an op amp. could this be it?
anyone have any more than the first two pages of the CEM3310
datasheet, so that i can check it out for myself? :)
thanks
andy
