Note Value to CC: Linear Mapping shows strange Behavior.

Post by Leocity » Wed Nov 20, 2019 2:03 pm

HiFolks,

I am not sure whether I am dump or there is a Bug in the Note to CC feature.

Here is what I need:
I need the Notes C#5, D5, D#5 and E5 to be translated into CC10 with the values 0,1,2 and 3 and the notes F2, F#2, G2 and G#2 to the CC10 values 7, 8, 9 and 10. Sounds easy.

Here is what I tried:
I started, setting up one Controller: Note value to CC with the Input Range from C#5 to E5 and an output range 0 to 3. As expected, it works: These four notes will be converted to the values 0,1,2 and 3. But unfortunately the notes F2 to G#2 are matched to 0, because they are out of range.

So I converted it to a LIST. For the selected notes C#5 to E5 the list shows the values 0—3 and a 0 for all under and 3 for all above. Up to here everything as expected.

But now the strange behavior: From now on the tool is translating the notes to CC values as follows:
C#5 (CC10: 0), D5 (CC10:129 ), D#5 (CC10:2) and G#5 goes to CC10 value 131.

Why 129 and 131 instead of 1 and 3?

But it comes even stranger. If I put for the notes F2 to G#2 the values 7 to 10 the result are translations to the CC10 values 135, 08, 137 and 10.

So every second note is translated to a value above 127. Is it a bug or what do I wrong? Thanks for your support.

I found out that for each Note in the list view of "Remap Controler Note -> CC" the folowing happens:

For each "even number" it works fine. So if in the List I put in a value 2, 4, 6, 8 ... etc the result value of the CC command is 2, 4, 6 and 8.

For each "uneven number" 1, 3, 5, 7 ... etc it gives as a result a much higher value over 127.

1 -> 129
2 -> 02
3 -> 131
4 -> 04
5 -> 133
6 -> 06
7 -> 135
8 -> 08
9 -> 137
10 -> 10

Does that help to understand the issue?

Edit: This -in my understanding - wrong remapping behavior effects every outgoing parameter (CC, PC, SYSEX etc)

Hi, do you have "MSB + LSB" selected somewhere, instead of "MSB"? Can you maybe show some screenshots?

Best,
Johannes
