Dave Smith Instruments SYNTHESIZERS

Hello,

I am really considering purchasing a tabletop evolver or an alesis 
micron for live use with a drum machine (ya I know they are very 
different) and I was wondering if anyone could share their 
experiences with using the mono-tabletop unit or the micron live.

Basically, I am hesitant to buy the evolver for only a couple 
reasons.  I like to write music with a lot of layers, so the 
polyphony issue comes to mind.  I cant afford a pek or rack.  I 
understand you can sequence out each oscillator to make chords and 
different lines though.  

CAN you have the sequencer control one oscillator while you are able 
to play another oscillator from a keyboard controller?  --That might 
be a stupid question, but this thing seems kind of mysterious to 
what it can do.

Also, would this synth be good for composers on the "less 
experimental" side of things?  I personally dont need every patch to 
be 100% original to make cool music for myself.

Any help would be great!
