Akai VX600 EL-Foil replacement

The Akai VX600 is a very nice synthesizer. It's got 12 analog vco's, 6 independent multitimbral voices with individual outputs and its matrix has an input for voltage control. In other words: it's extremely flexible and useful in an analog setup. The fm is also very nice. It has some negative sides too: personally i'm not very impressed by the envelopes and the lfo's, there's a horrible bleep coming from the backlight and the filter can sound like a tin can occasionally.
