GMS-744MU Multichannel MIDI/CV Converter

Up to 8 Channels of high resolution CVs, Gates, & MIDI Clock

The MIDI to CV Converter module is designed to convert MIDI note commands into corresponding analog voltage level outputs to be used by devices such as voltage controlled oscillators in analog synthesizers. In addition to a changing analog voltage on one channel, the module can also supply a second analog voltage corresponding to the MIDI velocity information. This analog voltage can be used to vary the response of an envelope generator to allow the channels dynamics to be controlled by keyboard velocity information. 

BASIC FUNCTIONS     

The GMS-744MU Multichannel MIDI to CV converter contains eight complete converter channels, each channel capable of producing an analog output and a gate output. When a two channel mode is selected, one analog channel will produce the voltage equivalent of the input MIDI note value, one analog channel will produce the voltage equivalent of the MIDI velocity value, one gate channel will produce a gate signal for the duration of the MIDI note on to note off time, and one gate channel will produce a 25 millisecond trigger pulse.     

POLYPHONIC OPERATING MODES

• Two channel with gate and trigger

• Three or four channels with gate

• Two channels with separate sequential MIDI channel numbers

• Four channels with separate sequential MIDI channel numbers

 ADDITIONAL FEATURES 

Each channels can be assigned to a MIDI channel to listen on. Assigning multiple channels to the same MIDI port engages polyphonic note handling. If the setting is not modified by system commands received on the port, the channel also serves as the default analog output channel. These settings are made through menus displayed on the front panel OLED display. Settings may also be stored to and recalled from internal non-volatile storage.     

The MIDI clock on the input channel is divided internally and output on the MIDI CLOCK output jack. Divisor ratio is set through a clock control menu. The module also outputs a clock run signal on the clock output connector that can be used to start, stop, or pause external sequencers to maintain synchronization.
