Common waveforms in synths, pic->wav, MIDI2CV8 power req

     The ASM-1 will run fine on +/- 12 or +/- 15 volts. Other than that I 
     have not tested.
     Regarding LEDs - I agree - the more the merrier. Places they can be 
     Envelope Generator - gate indicators
     LFO - the full-strength square wave (+/- 15V) is present on the RATE 
     pot, so it's a simple matter to hook it to a nearby LED as well. Use a 
     fairly high series resistor, like 1K to 2.7K, so the comparator 
     op-amp's output doesn't get loaded down too much which may affect LFO 
     waveform symmetry. Experiment! Bi-color would be cool here.
     I personally prefer to solder chips directly in, without sockets, so 
     that there are no corrosion/poor contact/vibration issues waiting in 
     the future. This applies to op-amps, 3080's, 311's, etc. but for 
     expensive and salvageable chips like CEM's and SSM's I always use 
     sockets anyway. Usually I use brand new parts (out of tubes, fresh 
     from the distributor) so I'm sure that makes me confident enough to 
     risk the difficult removal problem - but if my parts were scrounged or 
     somehow of doubtful origin, sockets get used.

1) One power supply should be able to handle the MIDI2CV8 and the ASM-1, 
right? If so, any power supply recommendations? 
2) I tend to like LEDs on modules - not only because they provide 
diagnostic information but also because they look neat. (: Any tips on 
hooking up LEDs to the ASM-1?
3) In the past, I've found soldering ICs to be a major pain. Any general 
tips on soldering ICs other than "go to it and good luck?"
