Apart from being able to create those 'generic' analog tones with quite some class IMO (it is a moog after all ;-), I think two things make it special: the very fast envelopes (for those ZINNNGY percussive noises)and the overdrive for some dirtyness.
Not sure what you mean by "ZINNNGY percussive noises" or "overdrive for some dirtyness" the latter meaning distorted effect perhaps?
Modulation helps to be 'special', too. It is quite a simple synth so just twist those knobs and assign the lfo to all destinations possible..
If you add the special CV outs/ins (or have a version that has them already fitted) you could further modulate or incorporate other CV gear...
If you want more options, you can always get a voyager
Well the CV almost cost as much as the Alesis Micron, which has proven itself to being more fruitful in production than the Phatty. Having the ghastly feeling that I've made a mistake in purchasing the LP I wont be investing in it much further. It has also put me off the voyager greatly.
So is it safe to assume that I've thrown my money away? Or is there some secret synth-programming techniques that I as a new generation digital user have no clue on?
