Super low frequency LFO
1999-05-05 by Dave Bradley
One of the first things I found out about the MOTM-300 after getting it running last night was "how low can you go". In typical fashion, as soon as I got it running, I tried to blow it up! I cranked a sawtooth wave all the way down with the coarse freq controls, no external CV in, and got the 1 cycle per few seconds as advertised. Then I took the pulse output of the same oscillator, set the pulse width to minimum, and ran it back into FM2 with the attenuator wide open. I don't know exactly how low it got, but during a single cycle I literally had time to stuff 2 more VCO front panels with jacks, leisurely digging them out of bags and dropping them on the floor, etc. Say 1 cycle per 10 minutes. I know we don't want to use up our VCOs as LFOs, but it's really nice to know that the VCO handled a large negative CV at the bottom end of its range by doing what I hoped for rather than blowing chunks.
