Kawai K3m

“Kawai K3m 6-voice rack synth module for sale, in Excellent condition.

Sale includes RC2 cartridge, a ~$75 value.

It’s a US Version (110V), only for sale to customers in N. American and Japan. The rackmount format gives you all the power of a classic 6-voice hybrid synth in a nice compact package.

This particular K3m unit is in VG to EX shape. All buttons and LCD characters are fully functional as well.

The SSM2044 analog filter (same as in PolySix) is makes this synth shine. Many describe the filters quality as smooth, round, kinda softer than CEM filters.

It includes an as-is storage cartridge. It does not appear to be working but perhaps its a bad EPROM. (A RC2 cartridge doubles the on-board patch memory to 100 patches you can call up instantly).

The unit also has a nice variety of LFOs as well, and even a primitive additive patch.” Click here to search for synths on eBay

Kawai SX-240

“Tested and working good!
Less than 950 SX-240 were made total and even fewer still exist today! Rare!
I acquired this synth many years ago, it was in working condition but had issues that are now fixed + customized!
When I got it, it had a bad voice, the end cheeks were chipped, cracked and ugly, and there was a small amount
of rust at the very edges of the control panel. The rust was lightly cleaned and then covered with black satin tape
strips, i am not an expert here and did not want to make things work with the pair or graphics.
The ENTIRE voice board has been replaced with a BRAND NEW ONE! (NOS directly from Kawai US)!
Has TAUNTEK OS installed which gives it full MIDI capabilities including external CC control change and individual MIDI channel selection!
This means you can hook up a knob box or computer and control filters, envelopes, etc! It also allows for separate MIDI channels when using split mode!
The end cheeks have been replaced with REAL WALNUT end cheeks! (So much nicer!)
All they keys have been replaced with Gold and Silver 3D printed keys, buttons too! Even has a custom RED memory write button!
The Silver vs Gold keys denote where the “split” is when you pay in split mode. This makes it easy to see the split while
playing in split mode, even under live stage lighting conditions thus minimizing the mistake of playing a bad note by playing past the split point!

Decent used condition – See photos
