On a specific channel is there a simple way of toggling mute off and on
Ie stop all notes from playing then toggle to have them start playing again
A real acoustic instrument is being fed so just reducing velocity to zero does not work

Hi
There are a number of ways to do this depending on what equipment you are using.
Changing the Continuous Controller 7 (CC7) is volume and its value can be made equal to 0 to mute and back to its original value to non-mute.
If you want to leave the volume where it is, there is CC11 (expression) and you can switch it between 0 for mute and 127 for non-mute.
The notes still get sent, but you can't hear them.
Another way is to use MidiOx.
Start by setting up two Data maps.
The first does nothing - this is the non-mute map. ( you just add a blank line - press clear then press insert then save map) "Thru.oxm"
The second has
Input = on your channel, Note On, all values = -1
Output = Match Input, Discard to throw away the Midi Note On message. "NoNote.oxm"
Make sure the Data Map is turned on.
You then set up a Patch map and, for example, make Patch 0 Map Location the "Thru.oxm" and Patch 1 "NoNote.oxm
Make sure the Patch Map is turned on.
You can now swap from 'Thru' to 'No note' with a patch change.
All the best

Thanks Did not make myself too clear
The output is driving a solenoid operated harpsichord Even with velocity zero the notes are still sent
The other suggestion seems to work

You might like to fix the harpsichord's firmware as Note On with zero velocity is the same as Note Off.
Most Yamaha keyboards only use Note On messages and turn off the note with a Note On with zero velocity.
Many others are the same.

I converted a harpsichord to midi operation using small solenoids to operate the keys The midi to parallel conversion is done on a commercial available board There is no means of programming the board not to play when it senses a zero velocity note on
Good idea however
