I have the nybblize code and half the controls working here:

Import modulators from spreadsheet or csv would be cool too.

@goodweather I think packDsiData does something different than what I need for the Quadraverb…

	console("i   quadraveb   packDsiData")

	for i=0,300,31 do

		mb = MemoryBlock(string.format('%.2x', i))
		packed = utils.packDsiData(mb)
		dsi = packed:toHexString(2)

		qv = encodeQuadraverbData(i,2)

		console(string.format("%.2x   %s   %s", i, qv, dsi))
	end

gives…

LUA>> i   quadraveb   packDsiData
LUA>> 00   00 00 00   0000
LUA>> 1f   0f 40 00   001f

That step-by-step guide is mandatory for Ctrlr learners.

Here’s where I ended up for encoding the Quadraverb params. I have not tried to encode an entire patch yet.

encodeQuadraverbData = function(data, numBytes)

	orig = BigInteger(data)
	reversed = BigInteger(0)

	-- reverse bytes so lsB first / msB last
	for i=0,numBytes-1 do
		byte = orig:getBitRangeAsInt(i*8, 8)
		reversed:setBitRangeAsInt((numBytes - 1 - i)*8, 8, byte)
	end

	requiredBits = numBytes * 8
	encodedParts = math.ceil(requiredBits / 7)
	encodedBits = encodedParts * 7
	zeroPadding = encodedBits - requiredBits

	reversed:shiftBits(zeroPadding, 0)

	bytes = {}

	for i=1,encodedParts do
		byte = reversed:getBitRangeAsInt(encodedBits-(i*7),7)
		table.insert(bytes, string.format('%.2x', byte))
	end	

	return table.concat(bytes, ' ')

end

Thanks again for the help. There is a lot of good stuff in the Power08 example. I am getting things to work now. A newbie has to realize two things:

1. Connect Lua methods to the panel by properties like “Called when…”.

2. When you save your Lua, use “Save and compile all” to test your changes.

Thanks goodweather and possemo! packDsiData looks close to what I need (Alesis data bytes are reversed) and I can see how to build the transform from passemo’s code.

How do I actually get this code to where it’s needed? I see how to implement a new method for “Called to calculate MIDI value to send” but I haven’t seen documentation for what args it receives and should return. Shouldn’t I be able to setup sysex output to always use f0, my vendor & device code, then f7 after?
panel:sendMidiMessageNow(CtrlrMidiMessage(“f0″..”00″..”00″..”2F”..”01″ does not look D.R.Y. 🙁
