Crudlabs Crudman – Walkman based synth
The Crudman, above, is based around a Walkman which has been elaborately hacked so that a tape of a looped or droning sound (or any other sound) can be precisely sped up or slowed down, via MIDI or 1v/octave CV, to accurately hit notes over a range of 3 octaves.
The Crudman can be used monophonically, or multiple Crudmans can be used polyphonically.
The Crudman can be played just like a synthesizer with MIDI or CV in. Standard synthesizer parameters – ADSR, pitch bend, portamento, can also be set using MIDI Control Change messages.
To use, put in a tape tuned to C, and you can play all the way from C two octaves down, to C one octave up – 3 whole octaves.
While the concept is simple, the developer says that a great deal of research and experimentation has gone into building the most powerful cassette Walkman instrument possible.
