This was produced around 1980 by Crumar and an Italian company called Music technologies. This particular model does not have the Crumar brand on it.It produces a basic analog synth bass sound with simple controls for Envelope, Cut Off and Resonance.You can also choose to have release controlled by the sustain envelope controller, change the wave form, and control octave via footage switch. There's a doubler as well which gives the sound a chorus-like quality.This item has had a little light restoration:
ensured that it was tuned to scalenote footage switch changes octave but slightly offsets the tuning - this can probably be corrected internally if you are not afraid of electronics. I may also try to correct this before sale.buttons are working and cleaned, tightened.
circuitry checked and lightly cleaned of dust.This was used for a sounds in a video game project Atlas Reactor and I no longer need it anymore.A great sounding piece of kit and in nice condition! Hope you enjoy it as much as I did.
