Dope synth

Based on (modified) doepfer synthesizer modules. The frame comes from a Revox A77 tapemachine.
An alternative Dave Krooshof - Leon Spek - interface will be added. Montage & design: Dave Krooshof 2004
 
Update 31 dec 2004: I made the input interface, but I have not added it to the dopesynth yet.
I took the instrument to Ernst, who made this recording of a testdrive.
The instrument is amazingly light weight. I will add an internal speaker, which should be loud but light as well.
