I have an Evolution EVS-1 for sale which may be interesting for the ones who
cannot build a MIDIbox FM.
A Windows editor is available at:
http://www.deepsonic.ch/deep/freeload/evs-1_edit_0.2b.zip
As an alternative there is an editor for Atari.
The location is Cologne in Germany.
I have a user manual in english (printed) and german (original) and
the original PSU for use in Germany (I have no idea with which countries
it is compatible :-[)
This synth is extremely underrated and definately better than the Yamaha TX81Z.
Asking 60 Euro + shipping.
