MFOS Sequencer with Custom dual gate sequencer
video upload by O.Z. Hall
"Music from Outer Space Sequencer with MOTM panel designed by DJ Thomas White. I've created a custom module for adding two additional GATE sequencers for extra percussion. I also have a separate CV output for the inner row of knobs. Together with one of the GATE sequencers, it is possible to have two sequences at the same time (same tempo, same end step, same direction).
One other customization is a module (to the left) which will shift the level of a gate to allow a +5V gate to drive the internal clock of the MFOS sequencer. This module also contains two LFOs and two 4:1 multiples.
Finally, the voice you hear is made up of the first 5 modules on the lower row of this rack case. There is a dual oscillator, a Prophet 5 Rev 2 filter (with NOS SSM2040 chip), a programmable ADSR/LFO/Mixer with 3 extra programmable CV outputs to control Resonance and two other parameters. There is also a dual VCA.
The two percussion modules are an MFOS 8 stage phase shifter and a state variable filter modelled after the eMu Universal Active Filter. The phase shifter makes a percussive sound when the audio input is "pinged" by the gate output. It responds to both the GATE on and the GATE off. Thus, the "double time" rhythm. The second eMu filter is the first percussive sound you hear added to the sequence."
