"Up for auction is the mighty Korg Mono/Poly. You probably know all about it so let's talk about this particular unit:
It is a european version (220v) and one of the latest model (you can tell by the PCB revision).
The unit is in very good cosmetical condition. The wooden side, which are the weak point of the beast, are here in a rather good condition (though there are some scuff on the corners). The only real esthetic flaw are the two wheel intensity knobs that are not original ones.
Electronically it is working perfectly. I have serviced and calibrated it. The filtre chipset (SSM2044) and main cpu (D8049c) are new.

And also I did some modification that improve the MonoPoly a lot:
- MG1 normal/fast speeds switch: add a fast speed mode for MG1. This allows for more metalic and FMish sound when used in FX, VCF modulation or PWM.
- VCF EG speed switch: add a fast speed mode for the VCF enveloppe. It make the enveloppe and synth snappier.
- VCA EG speed switch : same as above but applies to the VCA
- Disable the reset of the keyboard algorithm when switching in FX-Mode
- Disable the reset of MG2 when playing a new chord in arpeggiator mode"

Elektor Formant Analog Synthesizer with Keyboard

via this auction

"This is an Elektor Formant synthesizer with keyboard, 5 octaves.
The device has a very clean and consists of the following modules:
- 2x ADSR
- 1x LFO
- 1x NOISE
- 1x Dual VCA
- 1x COM
- 2x VCO
- 1x VCF
- 1x VCF 24dB
- 1x RFM
- 1 x Keyboard with INTERFACE, 5 octaves

In addition, a front panel with switches and potentiometers fitted for a third VCO module, cable keyboard / synth, 3 patch cable 3.5 mm jack, and 6 pieces 3.5 mm metal plug.

The keyboard is very good, the unit is working as far as I can see that, except for the following defects:
- Some Poties scratch easily, can be solved safely
- 24dB at VCF module Q knob (slope) is not operational. The module filters otherwise, the signal comes through normal (normal VCF module works perfectly)
- RFM module with no obvious function for me (maybe not I get it too ...)

For a hobbyist, it is certainly not difficult, they back up and running modules, unfortunately I can not have time to deal with it.

Shipping in Germany 25 euros, which will be 2 heavy packages on I would prefer a pickup, I'll also receive up to 50 km."

"This 440 works perfectly and comes with one floppy disk "wine country 441--1 Performance series" and power cord. This 440 has a new floppy drive, new pads, and a new slider from Wine country. The backlight does not work but the screen is still visible. the cosmetic is average for a close to 30 year old piece of music equipment, there used to be a scratch on the face and the previous owner took a marker and colored it in (you can see this in the pic)."
