13. Midi / Arpeggiator
The midi / arpeggiator section allows the Microvolt 3900 to respond to digital midi messages from a controller or
DAW by converting digital midi data into analog control voltages. In addition to basic midi functionality, this
section adds a powerful arpeggiator/note sequencer, tap tempo clock, and pitch octave transpose buttons.
Because the feature set of the midi / arpeggiator is deep, this portion of the manual will be split into several
sections detailing every feature.
Basic Midi Response
The Microvolt 3900 responds to midi note on/off, midi note number 0 - 127, midi clock, midi clock start/stop, midi
pitch bend, and midi control change messages. By default, the midi channel of the Microvolt 3900 is set to omni
allowing the synthesizer to respond to all midi channels.
The midi input jack(105) uses the supplied stereo 1/8” to 5 pin din connector to connect to a traditional 5 pin midi
cable.
Note pitch(104) is patched internally from the midi section to the pitch input(110) of the voltage controlled
oscillator. The midi gate output(106), representing note on/off, is patched internally to trigger the function
generator input(133) and the envelope generator input(118).
Two Performance Modes
The midi section has two performance modes, monophonic and arpeggiator. Monophonic mode converts midi
note on/off messages into monophonic 1 volt per octave CV and gate signals that are based on the incoming
midi note number and midi on/off messages. The arpeggiator mode creates a repeating sequence of 1 volt per
octave CV and gate signals based on the incoming midi notes.
