Collin’s Rockin’ Gakken MIDI-in DACin’ hackin’

Collin has quite a hack on his plate: a DIY MIDI-to-CV box. This will allow him to send MIDI to older/inexpensive synths that have a line into the VCO. It consists of a 12-bit R2R DAC built using a DC boarduino, a MIDI opto-isolator box and a Gakken 150 analog synth kit

  3. oop – beat me to it!
    well nice choice of subject matter then =)

    I was just moving the circuit to a perfboard when I realized,
    I could probably generate CV real E-Z on a hacked waveShield.
    alas, brain don’t like doin’ spi clockin’ an all that latch-up talkin’ – it much prefer resistor gawkin’
