Sends a MIDI note-on message, and appropriate MIDI values whenever the gate input goes over 0 Volts. The voltage at the pitch input determines the MIDI note number, and the voltage on the Velocity plug sets the MIDI velocity number.
Trigger to MIDI
Plugs and properties:
Left Hand Side:
->Gate:- (Voltage) Triggers the Note on message
->Pitch:- (Voltage) Sets the note pitch. For details see signal level conversions.
->Velocity:- (Voltage) Sets the note velocity. 0 – 10V maps to MIDI Velocity from 0 to 1. he default level is 0.5
->Channel:- (List) MIDI Channel number (or “All”) to output on
Outputs:
<-MIDI Out:- (MIDI) Standard MIDI 2 Output
Properties:
**Freq Scale:- Select from: 1V/Octave or 1V/kHz.
**Channel:- Select the MIDI channel number or “All”
Note: If you connect a MIDI-CV2 module to this module it will still produce the usual Trigger pulse as the Gate button is pressed.
MIDI Monitor.
Displays the MIDI status and MIDI values being received.
The display format.
Sound ON = Sound engine is running.
2C1 shows that you are using MIDI Channel 1 as the output channel.
Note on shows that the module has received a gate signal. Turning the gate off will result in a Note off output.
2C16 Note On (111, 0. 84):
Channel 16: Gate is on, 111 is the MIDI note value, 0.84 is the velocity.
2C16 Note off (111, 0.5)
Channel 16: Gate is off, 111 is still the MIDI note value, and the velocity has returned to it’s default of 0.5
2C16 Note On (116, 0.84)
Channel 16: Gate is on, the MIDI note is now 116, and the velocity is still 0.84.
MIDI Note to voltage conversion.
Note: By this table middle C (60) is C3, not C4 as per ISO system standardized by Acoustical Society of America
This conversion table doesn’t apply to MIDI note lists of the sort contained in the ‘MIDI Filter’ module. For those a simple ’10/127 x note number’ formula works.

The volts values can be fed to ‘Trigger To MIDI’ and ‘SampleOscillator2’ modules at ‘Pitch’ pin for example, the values can be calculated as well, but it’s not so straightforward and due to deviations product requires constant manual adjustment, the table saves you this tedious process, it’s accurate and verified
