External midi control clarification

I use my OT as a live sound mixer and primary midi sequencer for my Eurorack. I have it set up so each midi track controls a different drum or synth voice in the rack via different midi channels. I also have some midi CCs mapped so I can send LFOs from the OT to the Eurorack.

However, keeping track of the midi track LFOs and CCs is tricky and too menu divey when performing live. So, I want to find a way to use an external controller (some kind of midi faderbank) to control the CC and LFO values.

The last page of the manual (c.8 midi mode control change mappings) is a bit unclear regarding how to control these parameters. It says

“While in MIDI mode and CC DIRECT CONNECT is deactivated, the auto channel responds to the following CC messages.”

Does this mean that’s the only way to control the midi parameters externally? Or if direct connect is on, can I do it more…directly? If direct connect is on can I access all the parameters directly? What if some of the midi tracks share a midi channel?

For example: I have midi tracks 1-4 set to channel 13, which my drum module responds to. How could I use an external controller to turn midi CC knob 1 or the speed and depth of LFO 1 on track 3? And, can I do this without switching to midi mode and selecting that track?

I would forget about the CC direct connect thing, AFAICT that’s really just for turning knobs on MIDI-connected synths and having those parameters get p-locked in the OT’s sequencer.

All you should have to do is make sure the appropriate MIDI CCs are coming into the OT on the correct channels for the tracks you want to control. For example to control the depth of LFO 1 on track 3 you would make sure the knob you want to use for that is sending CC 31 on MIDI channel 3, assuming that your MIDI channel configuration on the OT is set to the default.

You can absolutely control all of the first page parameters for SRC/AMP/LFO/FX1/FX2 on all eight tracks if you wanted to, though you would need a monstrous MIDI controller.

ok. sounds like I was imagining the complexity a bit. and yes, I’m thinking about getting a bank of 16 faders or so to control a bunch of parameters without having to select that channel.

I suppose if multiple tracks share a midi channel, then a CC to control something on a given parameter page would just change it on all of those tracks. I’ll play around with this a bit before buying a controller.

Ok, so I’m testing this out, and it seems like I can ONLY control stuff on the parameter pages via the auto channel with the midi track selected.

I can’t control anything when CC Direct Control is set to on, so I have it off.

My auto channel is set to 16, and my midi track 5 is set to channel 9 on the SRC settings page. On the Midi Control 1 page, I have CC2 set to send out 71.

In the manual the midi CC to control CC2 is 37. If my DAW or midi controller is set to send CC37 on channel 9, nothing happens. If I send it on channel 16 while midi track 5 is selected, it functions as normal, even if I’m not on the Midi Control 1 page. If I send CC71 on Channel 9, it will work as expected. however this only solves half the puzzle.

what I’m really after is controlling the LFO depth and speed parameters on my midi tracks via an external controller. And, just like when I send CC37 to control CC#2 on the midi track, sending CC31-33 to control the LFO depth only works on the auto channel with the track selected.

So, is what I’m after actually impossible, or is there something I’m missing?

Ah I’m sorry, I didn’t read your post thoroughly so I misunderstood what you’re trying to do. I didn’t realise you were wanting to MIDI control the MIDI track’s parameters. Yeah so as far as I can tell it doesn’t seem like there’s a way to directly map to those like you can with audio tracks, aside from mute/solo functions.

So it seems like you may want to use CC direct connect so you can control the Ctrl1/2 stuff remotely, if that doesn’t prevent you doing other stuff you want to do. I don’t think that would let you control the LFOs though unfortunately.
