Begagnad Crowphonic CRO-1

A modular, three square wave VCO, sound and noise making device with frequency modulation (of 2 VCOs), sync type control, attack/release envelope, three vca (one per VCO), 1 square wave LFO and power starve (reducing the power supplied to the 4 oscillator chip for strange dying batteries sounds). It's four intermodulating square waves give a range of sounds from noise to evolving drone sounds to percussive zaps and beeps and more.

The patching of modular components is done by bolts emerging from the top of the box in a circuit bent type of style. The patch cords need to be crocodile clips. These allow you to patch several sources to a target or vice versa.

This synth is not geared towards playing tunes and will not give the correctly calibrated pitch response to do so. There is no midi, but CV control can be acheived by the bolt to croc interface on the box. For multiple connections leads with crocodile clip to 1/4'' jack or whatever type would be required.
