Metasonix R-60 Self-Tuning MIDI-CV Interface

The R-60 is a MIDI/CV-interface that automatically sets itself up to the correct voltage characteristic to control a connected VCO over the maximum possible range, in perfect equal tempering. The R-60 doesn't care what the CV response of the VCO is - exponential, Hz/V, whatever - it will try to tune it to equal tempering anyway.

Caution! The special price is only valid as long as stocks lasts.

Unlike all the other MIDI/CV converters on the market, the R-60 tunes and scales itself. Plug the CV output into the CV input of your VCO, and plug the VCO output (square or pulse waves are best) into the audio input of the R-60. Push the LEARN button. That's all
Functions: MIDI panic, note on, note off,sustain pedal(suppresses note off), pitch bend, modulation.
Pitch-bend and modulation settings can be redefined with CC messages: CC86 sets the pitch bend range (4 ranges), Modulation wheel sets the depth of the internal LFO, CC77 also sets depth of LFO (per midi spec), CC76 adjusts the LFO rate from ~10 seconds to ~30 Hz, and CC85 sets the LFO type (4 types: saw, square, triangle and sharks tooth).

The R-60 is monophonic, and has a 10-note buffer memory. Gate output responds to sustain on/off MIDI commands. Retriggering allows trill effects.

All settings, including the current CV tuning table, are stored in non-volatile flash memory. The R-60 may be reset by holding the learn button down during power-up - this erases the stored tuning table and all other stored parameters.

The R-60 is fully protected against reverse supply voltage, overvoltage, undervoltage, or incorrect hookup to external equipment.
