Moog MF-107 FreqBox used as a Second Oscillator.

MicroMoog and Freqbox from Rhythmicons on Vimeo.

“Good evening ladies and gentleman my name is Eric from the Rhythmicons demonstrain’ some Moog products.” Specifically Eric uses the FreqBox as a second Oscillator for a old Micromoog. Things get fun at about 3:33 in. The USA flag surely fits in this Arkansas Moog kitchen!

Here’s how Eric did it:
MicroMoog Kbd out to Cp251 Attenuator
Attenuator out to Freqbox Frequency input
Freq Out to Audio Input of Freqbox.
Audio output to MicroMoog Audio Input.
