Korg Z1

Korg Z1 Image

The Z1 is like a polyphonic Prophecy housed in a full sized and featured Trinity workstation-like casing! 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.

My Z-1 Arrived today. It's in near mint condition. Cost was $549, w/DSPB-Z1 Expansion Board included. (great deal!) I must say the Z-1 is rather MORE than I expected. I have an EXB-MOSS installed in my Triton. (& I love it!) I thought the Z-1 would sound identical, but w/12 voices instead of 6. (or in my case 18 w/the Z-1 expansion) Well that doesn't seem to be the case. The Z-1's sounds seem richer, thicker, clearer, more intricate, etc. It seems superior to the EXB-MOSS, in more than just polyphony. The Z-1 is awesome & is fast becoming one of my favorites synths! I love it!

Agent86 - Are you sure? I just bought on Ebay, a Korg Z-1 expanded to 18 voices. (it has EXB-MOSS installed) So is there no difference between what I just bought & an EX? Does the EX have anything extra or different? Different & or more patches? Different DSP, etc?

I bought the very last unit from my local shop. I never regretted it. This synth is massive in power and architecture. 13 years on and still learning things. It is hard to program with so many screens, although the layout is quite logic. The three oscillators, 4 EG and 4 LFO make some amazing FAT sounds. There is a LFO shape which is "Vector Random", adding it subtly to your sounds you have that analog drift that makes everything so much more interesting. You can make oberheim sounding pads, amazing strings, Pro One-ish basses, but also weird FM-ish percusive stuff... I love it.
