This keyboard uses the Doepfer "A-100CGK" electronics kit plus a little
extra. It is housed in carefully cut, sanded, stained, and finished
hardwood, and has a nice aluminum panel made by Front Panel Express. It
weighs about 6 lbs and measures 21 inches long by 7.5 inches deep by 3.75
inches tall.
It uses a 2 octave Fatar keybed. The tracking scale has been tuned to work
perfectly with my rs95e oscillators but can be adjusted if you so desire. It
has pretty good velocity sensitivity. It also features aftertouch but that
is not very sensitive. It has polyphonic midi output as well. The controls
are pretty nice and feature a three character red LED display. You can
quickly transpose up to 3 octaves, or by semitones. You can also change the
priority (lowest, highest or last note). You can also change the retrigger
time so that there is a slight pause of variable duration in the gate when
you press a new key so that your envelope will retrigger. The type of gate
can even be changed to work with any analog system. See the Doepfer website
for more details.
Other than the Doepfer electronics are two passive circuits with pots: An
attenuator and a simple RC filter that is for slewing a gate signal. It
works pretty well and can get you an ASR envelope variable from really short
to about 2 seconds.
Considering the cost of the material and the labor I put into it, I think
$500 is fair, but I will also take the best offer. It works great and is in
great condition, but I ended up not using it much.
If you live in the US I will include a free power supply.
