On a journey with the Moon Modular
The M 551 is a module, which transforms an attached Midi signal into a couple of analogue control voltages. Thereby modular synthesizers can be integrated into a Midi-network and controlled by Midi-master-keyboards or Midi-hardware- or software-sequencers/DAWs.
The M 551 derives the following six control voltages from the fed Midi-messages:
– Keyboard CV (from Midi-note-number) Depending on the ‘Priority’ switch, the lowest, highest or last received note-on message is getting transformed. Voltage range: 0-10,53 V
– Gate (from the current Midi note-on/note-off commands)
– Velocity (transforms the key velocity [note-on velocity] of the current note-on message) Voltage range: 0-10 V
– Mod. Wheel (derives a control voltage from Midi-modula- tion messages [Controller 1]. Voltage range: 0-10 V
– Pitch Wheel (control voltage from the Midi pitch bend commands, bipolar) Voltage range: ±5 V (If “Add Bend CV” is active, a pitch bend voltage of ±0,5 V is added internally to the keyboard control voltage).
– Controller (transforms a selectable Midi controller into a control voltage [0-10 V])
Available are: – After touch – Breath controller (CC 2) – Foot pedal (CC 4) – Sustain pedal (CC 64) – Panorama (CC 10) – Main volume (CC 7), – the unspecified parameters CC 20, CC 21, CC 22.
The functions of the three toggle switches are:
– Add Bend CV
In ‘on’-position the Midi Pitch bend voltage (attenuated to ±0.5 V) is added internally to the keyboard voltage to ease pitchbending the oscillator
– Priority
Keyboard control voltage/gate signal/velocity voltage are derived from the hightes/lowest/last received note-on message
– Keyboard Mode
Retrig triggers a new keyboard control voltage/gate signal combination at any struck key
Legato starts a new event not before all keys are released
To select the Midi-Channel: Dial the rotary switch to the„Channel Select” position and initiate a MIDI-channel message (e. g. strike a note on a keyboard); the module sets itself to the most recently received MIDI channel (this setting is saved even if the unit is switched off).
