Tracker + Bluebox, no luck sending MIDI CC

Anyone here have any experience using a Tracker for sending MIDI CC to a 1010 Bluebox? I can’t get it to work properly. The Bluebox has a MIDI Learn mode, which recognizes any channel and CC number you send to it. The MIDI channel is recognized, but I can only set the CC number using the Tracker’s note values. And when actually sending the CC values, the Bluebox only responds by invoking some sort of on/off command, where you see the value peaking from minimum to maximum and back.

Also tried it from a MIDI controller into the Bluebox, works just fine. And the Tracker can send MIDI CC to other devices without a problem.

So here I’m setting MIDI CC number 30 on channel 16, curiously enough by changing the note values. The FX is set to MIDI CC A, which sends on CC number 30. So I think that’s all correct.

Apparently, something seems to be off in the MIDI learn process of the Bluebox. Because I’m able to set the channel/cc-number mappings using a MIDI controller, and when I then switch to the Tracker I’m able to send the correct values to the Bluebox. This is cumbersome, but it actually works.

When I’m monitoring the MIDI signals, what’s being sent from the controller and the Tracker looks to be exactly the same.

So I wonder what causes the MIDI learning to be different. Only thing I could think of is that the Tracker uses TRS type B while most devices use A, and I have the feeling that when MIDI learning from the Tracker, some values just get reversed (ie. using note number for changing cc number).

Now, I don’t have a Bluebox, so I’m very much just fumbling in the dark here. But that doesn’t stop me from suggesting things:

What happens if, while Learn is enabled, you change the value of the a FX instead of changing the note value? And why do you have a note value at all? I assume you don’t want the Bluebox to play a note, and maybe the Bluebox is confusing the note value with “CC number” (at least that’s what it looks like to me) or they also implemented changing the CC number via notes, because that might be useful with MIDI keyboards or what do I know.

In other words: What happens if you try what I show in this GIF while Learn is enabled on the Bluebox?

That’s the solution, thanks so much! :heart:

I did try this before, without any luck, but there appeared to be one little catch. The Bluebox doesn’t register the CC number until a certain amount of value changes have been sent. This means you might have the settings perfectly right and then when you send a couple value changes from the Tracker, nothing is registered. So I was under the impression that this method wouldn’t work, but it does!
