hey! cool good information! sounds like a mk2 with the rotary pot on pcb needs to be on the cards.
there is a mixer output for the link port coming that deals with the offsets but also doesn’t have to incase a mk2 comes along. so ok here goes!
would be cool making it the same looking from the front ill just change up the back and also add a sine wave (I never use one… but lots of people ask for it!)
ill get on it next week. ill post up a rough adjusted schematic… thingymajiggy.
regarding Pwm may do it with an external comparator? as it seems there is a opamp left in my list … 2 tl074’s 1 tl072. this may negate a few components (always a fan of keeping component count low)
if a sine is added there is space for 1 jack socket… choices?
EDIT “”"" So after having a bit of a think. maybe a sub output just a square wave 1 below could be good. Or because there is scope and room for 2 knobs still with lots of space. maybe even a wave shaping output or a morphing output (however between standard waveforms the outcome in my opinion isn’t that interesting, so wave shaping could be funky)
