CQ mixer and Elgato Stream deck

CQ CQ General Discussions
1

I am sharing with you my settings to use Deck Plus with my CQ12T.
I am using the powerful and free Trevliga Spel midi plugin Home
I have made a simple setup to control 2 Mic fader, USB fader and Master fader, plus the corresponding Mute.

Editing is a pain in the ass with this forum…
Some corrections and explanations:
-I am using Stream Deck Plus by Elgato.
-there is not so much about NRPN into the CQ Midi protocol manual.
-to find the NRPN value for a fader, I use Protokol Protokol | hexler.net or any midi data monitoring software.
-for example, fader 1 to 10 = NRPN 8182 to 8201, Main fader = NRPN 10112 etc…

This is very cool and I’m glad you managed to get it going, but concerned about your comment that there is not so much about NRPN in the CQ MIDI protocol document.
It does have every NRPN for the CQ listed and explanations and examples for every type of message, so please let me know what else would help?
I did notice that you’re using decimal representations of the NRPNs though, and the document uses hex, is that the issue?

If so, to get to the decimal number:

  • Take the MSB from the protocol doc
  • Convert this from hex to decimal
  • Multiply it by 128 (because NRPN is made up of two 7bit values for 128x128 possible values, where every time the LSB goes over 128 it resets and the MSB ticks over once)
  • Convert the LSB from the protocol to decimal and add this to the MSB value

So for input channel 2 level to main LR for example, it should be
NRPN (hex) = 0x40 0x01
0x40 = 64
64*128 = 8192
0x01 = 1
8192+1 = 8193

Thanks,
Keith.

Tks for the conversion explanation.
Indeed what would help is the decimal values.
But as I said Protokol is very helpful also and already did a board myself for all midi NRPN data.

Here are my board for decimal NRPN midi.
