Korg • Z1

Could this be Korg's masterpiece? The Z1 is like a polyphonic Prophecy! It does all the analog sounds and more. This is a great analog modeling synth with 12-voice polyphony, thirteen waveforms, four LFOs, two resonant filters, two effects units and more. The ability to create unique sounds is endless. The factory patches could use some help, but overall the sound is very nice! It has a fully polyphonic arpeggiator that blows all others away. It has five preset arpeggio patterns and fifteen user patterns. Unfortunately there is no on-board sequencer. There is incredible real-time control available with knobs to control the two resonant filters, and a touch controlled 'XY' pad for tweaking patches in real-time. The Z1 is used by KMFDM, Gary Numan, LTJ Bukem and Orbital.
I had to part with this for spending cash and because I got weird about playing it as the band I did the most with it in, I got kicked out of...(plus it's really heavy, something to keep in mind if you wanna gig with this thing)
An advice for those who think it sounds digital and sterile: You can link filter 1 with filter 2 (in serial mode) on the filter routing page. Yes, you'll loose the 2nd multi-mode filter, but your Z1 will sound very warm and analog. PWM can be achieved on the oscillator page; it's called 'Wave Form', and it can also be even applied to saw waves. If you want it to sound even more drifty, there's a random feature. So yes, it's possible to get a lively analog sound with a Z1.
It can take a while to figure out how to get the best out of this synth, but it really worths. Once you master it, other polysynths - analog or digital - are no longer a real temptation.
Only kept Z1 and V-Synth. The synthesis is superb, fx are weak, interface is... totally stupid - no direct octave shift buttons?!! Crazy. No dial wheel either :( Buttons are crap, they begin to fail pretty soon. It's a shame Korg never improved or re-worked this idea (moss exb doesn't count).
Korg should continue Legacy software line with soft Z1, call it MOSSS.
