Korg Z1


The Z1 is like a polyphonic Prophecy in a workstation! 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.

Nice keyboard touch (for synth-action key), nice aftertouch.
X-Y is good for some effects, but not usable every time.
Changing program cost 1-1.5 seconds.
Need some tricks for playing in multitembral mode clearly.
P.S.: Now i looking for Korg Prophecy, cause i know - this is REAL synth too!
I bought mine for 800 dollars and that's a great buy. For people who are looking for a superb VA synth, try this if you can get one. A programmers dream.
A must try or buy.
