Re: What programming platform to build a sequencer?
If I'm reading this correctly, everyone has assumed an architecture where the microprocessor generates the CV outs directly (hence all the DACs etc), which is certainly valid. For an absolute beginner project, though, you might consider an alternative : have the micro just outputting steps, and then...

Re: Super Psycho LFO vs Psycho LFO
i use a couple of psychoLFOs all the time to introduce a little wobble into various modulations... i usually increase the osc. caps to at least 10uf to slow it down. i also have a superpsyco, all the additional options (and panel real estate) dosesn't really add too much musical functionality, at le...

Re: How to redesign a panel without any source files or information
i use graph paper, make a rough guess and draw it out, and then literally place the pots/knobs/switches/jacks on the paper to see if everything fits, and adjust where it's too close.

i have PCBs available for this: http://fluxmonkey.com/fluxmerch_buchla.htm. it runs fine on 12v without changes. the outputs swing close to the rail, though - i usually build mine with attenuators on the panel for each out, or voltage dividers behind the panel to bring them down to a more reasonable...

rather pleased with how this one came out... 3-way range switches, 2-input passive mixer to the 386 amp. gonna replace one of the mixer ins w/ a passive tone control (LPF-ish). it's gnarly.

Re: [AVAILABLE] Fourses Tarp PCBs
Awesome, thanks. I was thinking of building this and didn't fancy it on a paper circuit. It looks like you've corrected the mistake on the paper circuit as well. :tu: I've ordered two to make a double tarp, maybe with a shmance instead of the eight knobs. mistake?? :? only Allah is perfect :hail:

Re: Using FPD for paper drilling template?
I print 2 copies: one glue on w/ rubber cement to use as a drill guide, then i strip that off and use spray adhesive (scotch77) to glue on the final paperface copy. i also often use a self-adhesive laminate sheet, with the top/bottom wrapped around and behind the panel.
