Is it possible to set up a control to send out pitchbend data. I know the editor doesn’t currently support this but can I edit a json to do this ?

I hear you @RobinC 🙂 I will try to get pitchbend and aftertouch to the next firmware version. I need to coordinate it with @Tomas as the changes will be needed in both the firmware and the editor.

For the time being - @RobinC I do that with a Lua function:

```auto
function handle_slider (valueObject, value)
	    local control = valueObject:getControl()
        local id = control:getId()
        local channel = id % 6
        local pitch = math.floor( (value * 16383)/100 ) - 8192
        midi.sendPitchBend (PORT_1, channel, pitch)
end

```

Then assign `handle_slider` to a virtual parameter slider set values 0 to 100. Maybe this can help you.

thanks for the tip. I’ll see if I can adapt it to what I want

Pretty much works though I’m missing the bit when pitchbend is sent to the electra to update the control. I’ll see if I can get lua to handle that

thanks for the tip though
