Korg X3

The nineties update to the legendary M1. Launched in 1993, it expanded on what made the M1 such a great machine and featured a range of solid, entirely usable sounds. The Strings and Basses are exceptionally good, although truly analog sounding sweeps and pads are not what this machine was about. The X3 (and subsequent X-series models that came after it) was designed as a middle-weight workstation, with the warmer and more powerful 01/W series taking the reins as Korg's premiere ROMpler workstation of the early nineties.
The X3 is based around 6 MB of 16-bit multi-samples, with basses, guitars, strings, drums, pads and much more. You can even add more PCM sounds to the synth, but additional PCM cards are expensive and/or hard to find.

Detailed editing and a flexible sequencer make this machine more than capable of running a MIDI rig if you are averse to PC based sequencing. If you can live without large touch sensitive screens or resonant filters, then you will find the X3 packs more punch than you may imagine. A rewarding synth to own, even 10 years down the line. What it lacks in instant hands-on tweak-ability and cutting edge sounds, it makes up for in the ultimately usable range of sounds. It has been used by Vangelis.

If you own a X3 don't sell it...
When I played my first chord on the X3, I was shocked!
Didn't know what to expect, a device so old, has the best Strings sound
that I've ever heard!! and the best Accordion and church organ!
and it sounds real crappy in the Electro sounds...
It's as if this instrument was made for Metal music.
As a Metal keyboardist I've purchased it right away!
Even threw away my Korg X50 for it, and I barely touch my Roland Fantom now, I mostly use the X3 for everything!
It has a great feel in the keyboard itself, and the aftertouch reacts real fun, the sounds are fat and big, barely need compression to get out all the meat of it!
The only thing I'm gonna add to my gear is a 88 key MIDI controller,
to add more octaves to the X3's range.
The X3 is the best synth for Metal ever made.
