Midi to Voltage Converter

The MIDI TO CONTROL VOLTAGE converts MIDI data into analog control voltages. 

A MIDI note-on command gets converted into a keyboard control voltage and gate signal, the third output turns the note-on velocity into a corresponding control voltage. 

Three more output jacks on the left generate voltages from pitch- and modulation wheel controllers. The jack labeled “Controller” puts out a voltage from one of 9 selectable MIDI controller sources, e. g. after touch · breath controller pedal · sustain pedal panorama · master volume. 

Three toggle switches enable 

(a) pitch bending to be added to keyboard cv 

(b) change of note priority (highest, lowest, last note) 

(c) legato mode. 

The MIDI channel is selectable from 1-16.

M 551 CP

2-Channel Midi to Voltage Converter

 This DUAL MIDI TO CONTROL VOLTAGE module converts MIDI data into analog control voltages. MIDI note-on commands get converted into keyboard control voltage, gate signal and note-on velocity voltage. Three more output jacks generate voltages from pitch- and modulation wheel controllers plus a selectable controller source. 

This CP module offers two independent converters (A/B) to generate voltages for two-voice polyphony or twin-channel-use.

Control Voltage to 

Midi Converter

​

The CONTROL VOLTAGE TO MIDI CONVERTER module enables the user to integrate modern midi- and even computer-generated instruments and effects into his modular environment. Control your midi-equipment from your analog sequencer or from other control voltage generating devices. 

This module features four input pairs for control voltages (0 -10 volts) and gate signals to be transformed into midi-compatible control data. Each input pair can be independently transformed into one the following types of midi data: 

· Note-on/note-off · Velocity (w/note-on) · Pitch bend 

Modulation wheel (CC1) · Breath controller (CC2) · Pedal (CC4) 

Volume (CC7) · Panorama (CC10) · Special (CC20) · Channel after touch · Sustain Pedal · Program Change 

Note output can be transposed via midi information or control voltage.

M 553 

Midi-to-Clock Interface 

The MIDI TO CLOCK converts a MIDI clock into analog clock and gate-signals, to synchronize e. g. analog step-sequencers to MIDI-hardware- or software-sequencers. 

The M553 derives clock signals from the native MIDI clock resolution of 1/96 notes up to 1/4 notes. The right clock-output supplies a fixed clock signal of 1/16 notes.  The start/stop jacks supply relevant trigger-signals from MIDI start/stop commands

 while the two „note-on...” jacks supply gate signals, derived from MIDI note-on commands.  The MIDI channel is selectable 1-16.
