Hi,

This is an interesting topic!

What about the waveforms? I had an Arp Omni 2 and I remember it had a swith 
for "hollow waveform on/off", which sounded like that it switched between a 
sawtooth and a squarewave. Does anybody have experience with any other 
string machines?

I know binary dividers create squarewaves, but you can "stack" a few octaves 
together at certain volumes to get a staired sawtooth waveform.

Farfisa Compact organs seem to use some sorta hard synced oscillators 
(there's a word for it... "relaxation oscillator"?? or somehing... "blocking 
osc"? cant't remember...) as "dividers" to create pulse waves that have a 
sawtooth shape on the narrower part.

(neon lamp organs create sawtooths with their "dividers" but that technology 
isn't used on string machines I guess)

What ways are there to get sawtooth waveforms on string machines?
