It would be great to see MIDI out support for this so you could use it to sequence external gear.

Kawai K3m Rackmount Digital/Analog Hybrid with RC-2 Memory Cartridge

via this auction

The auction states the K3R is a wavetable synth, but it actually isn't. The oscillators have digital waveforms you can select from but they are not wavetables. It does have SSM 2044 analog filters (see this post). It is a nice sounding synth.

"It has 32 waveforms, some of which are samples of acoustic instruments like piano and percussion as well as some unique waveforms. By combining two of these waveforms you can create unique new sounds or add a twist to a traditional sound. Since there are only 32 of these waveforms, the K3 also features a programmable digital waveform where you can tweak the harmonic content of a waveform allowing for added flexibility and range of sounds."

Fender Rhodes Chroma Expander

via this auction

via the description:
"I bought this Chroma Expander in either 1986 or 1987 directly from Fender to use as a backup and programming synth when I was working with Josef Zawinul in all technical capacities. As you can see from the pictures, I added forced air cooling (a fan) to the rear panel and cut an air intake hole on the bottom of the synth adjacent to the power transformer location. I did this mod to all of Joe's Expander's and he had already had it done to his Chroma's. European Jazz Festivals in the summer were not forgiving to his analog synth gear. The fan will run at the same speed regardless of the Mains Voltage selected. Even though we never took this unit on the road with us, it had to be ready to travel just in case.

I have completely rebuilt the power supply. C3 is now 50,000ufd 16VDC rated allowing me to remove the OverVoltage Crowbar circuit and all Series Pass elements have been replaced as well as the rectifiers and electrolytic capacitors. The capacitors have been replaced with 105 degree Panasonic FC or Nichicon types with higher microfarad values. The Dual Channel Voice Card Motherboard has been upgraded as well. The batteries have been replaced with rechargable Li-ion types and the battery holder was replaced as well.

The Midi Converter is from my friend Ken Ypparila at Syntech and is installed internally. I will include a copy of the manual I made back in the day. The midi jacks are not labeled, however, I used patch-bay wiring convention of Send upper and Receive lower...

Shipping will be expensive. Roughly 60 lb.'s and because of double boxing the packaging will be 50 inches X 20 inches X 15 inches. "

Raymond Scott techno w/Cyclebox + Sound of Shadows

YouTube Uploaded by s0LVentCIty on Apr 8, 2011

"Hi my name is Solvent and this is my 3rd Eurorack modular system video. Today I've made some Raymond Scott techno, with the help of my newly arrived Cylonix Cyclebox and Flight of Harmony Sound of Shadows. I haven't really got a clue how to use the Cylonix yet, but I thought this sounded good, so I pressed record. Drums and everything else are being triggered/sequenced from the MFB Urzwerg."
