Is it possible to thin data or add a delay between CC messages in streams ?

[zmix]

I’m working on a panel for a MIDI controllable guitar pedal (the “Thermae” by Chase Bliss Audio), and having issues where it will stop responding to CC data. The designer suggested that it’s possible the pedal’s MIDI buffer is overflowing and suggested I insert a delay between messages. I can see that there is a provision for doing this when sending SYSEX data, but is it also possible when sending CC data?

You could use a Timer and a table of CC messages. When timer reach max count send the message and restart the timer. Add + 1 to table counter.

function timerStart()

	timer:setCallback (4, queryNextParametersFromList)
	timer:stopTimer(4)
	timer:startTimer(4,timerQueryTime)
	console("TimerStart")
end

function queryNextParametersFromList()

	local isConnectedBtn=panel:getModulatorByName("StartComm"):getValue()

	if isConnectedBtn ==1 and isMessageProcessed==true then

		
		queryCounterUpdate()
		sendMidiSysex(queryList[queryIndex])
		

	end 
end

function queryCounterUpdate()

	if queryIndex<queryListSize then

		queryIndex=queryIndex+1

	else 
		
		queryIndex = 1

	end

end

Excellent advice, thank you!!

I had to do a similar thing for my Jupiter 8 plugin.

What I ended up doing was essentially not having the controls send MIDI directly.

I set up a timer that sampled all parameters at a set rate. If they had changed since the last sample, I sent out an update.

It’s important to implement the timer in a callback otherwise the panel will be frozen until the timer expires.
