MIDI TX Speed on Ctrlr

[lecleto]

Hello Ctrlrs!

I have in my panel a function that copy a Tone1 parameters of Roland JV-880 to Tone2 setting moduladors and sending a midi message with new values for JV-880.
The problem is that sometimes I get a Midi Overload message and when I get this error I lost part of new configs. It seems that a lot of messages are transmitted at same time overload the midi in buffer by consequence.

Is possible generate a delay between each trasmited message or maybe reduce a Midi TX speed (data rate) of Ctrlr and with this action reduce a lost data and this overload?

Here is the part of code:

function copyTone()
	
    comboValue = panel:getModulatorByName("COPY-SELECT"):getModulatorValue()

    
    if comboValue==01 then -- Copy T1 to T2

       
        a = panel:getModulatorByName("T1-WAVEGROUP"):getValue() -- get the present value of modulator
        panel:getModulatorByName("T2-WAVEGROUP"):setModulatorValue(a,false,true,false) -- set the same value for this modulator, sending it to the synth
            
        a = panel:getModulatorByName("T1-WAVE-INT"):getValue()
        panel:getModulatorByName("T2-WAVE-INT"):setModulatorValue(a,false,true,false) -- set the same value for this modulator, sending it to the synth
        
        a = panel:getModulatorByName("T1-SWITCH"):getValue()
        panel:getModulatorByName("T2-SWITCH"):setModulatorValue(a,false,true,false)

end

Thanks in advance!

Hi,

Timer:startTimer(“integer interval in milliseconds”)
Timer:getTimerInterval(“const”)
Timer:stopTimer()

(See: https://docs.juce.com/master/classTimer.html#a3515b6e7a1e3777965e35686eaeb2da7)

Armed with Lua and the Juce Timer class functions, it should be possible to generate a delay.
I just started studying lua, ctrlr and Juce, so for now I leave it to others to work out the script :-).

Hi Lecleto!

Try

os.execute(sleep(125))

125=Milliseconds for example.

These two Juce classes may also be helpful:

MidiBuffer()

MidiMessageSequence()

Thank you Thomas and Dnaldoog!
The problem is solved!
Now I´m just trying adjust the time for best compromise solution.

This worked!

function copyTone()
	
    comboValue = panel:getModulatorByName("COPY-SELECT"):getModulatorValue()

    
    if comboValue==01 then -- Copy T1 to T2

       
        a = panel:getModulatorByName("T1-WAVEGROUP"):getValue() -- get the present value of modulator
        panel:getModulatorByName("T2-WAVEGROUP"):setModulatorValue(a,false,true,false) -- set the same value for this modulator, sending it to the synth
        os.execute(sleep(125))    
        a = panel:getModulatorByName("T1-WAVE-INT"):getValue()
        panel:getModulatorByName("T2-WAVE-INT"):setModulatorValue(a,false,true,false) -- set the same value for this modulator, sending it to the synth
        os.execute(sleep(125))
        a = panel:getModulatorByName("T1-SWITCH"):getValue()
        panel:getModulatorByName("T2-SWITCH"):setModulatorValue(a,false,true,false) -- set the same value for this modulator, sending it to the synth
        os.execute(sleep(125))

One more time, Thanks!
