Octatrack Crossfader Midi CC Not working

[huuh]

Hello everyone,

I notice a strange behaviour on my Octatrack. In one project the crossfader sends midi cc values to Ableton but in another no. I checked the midi configuration for both projects and i am not able to see any difference. The configuration is the next one:

• Midi Sequencer / CC Direct Connect : Yes
• Midi Control / Audio CC In: No
• Midi Control / Audio CC Out: Int + Ext
• Midi Control / Audio Note In: No
• Midi Control / Audio Note Out: Int + Ext

Midi channels are as default:

• Auto Ch: 11
• Trig Ch 1 to 1. Trig Ch 2 to 2 … until 8

And finally, Transpose enabled to send and receive. Clock only to receive and program change to receive only on Ch 14

I am checking the MIDI messages on a Midi monitor on mac btw, so there is no more devices involved. My idea is control Ableton’s crossfader

What am I missing ?

one particular caveat: are you sure Ableton does not filter channel assigned Midi Control Messages for the channel set to receive Midi on the Audio Track in Ableton? As far i know you can only circumvent this limitation by using max/msp objects. Apart from that your monitoring should be able to see it coming in.

Not clearly specified in the manual.
CCs midi channel used by crossfader and scenes also depends on Midi Tracks settings that can block Audio Tracks send.

Octatrack Tips & Tricks (OT Tips)

Crossfader and scenes are sent on the lowest midi channel of the audio tracks not shared with a midi track channel… Ex : if the lowest audio tracks midi channel is 1 and shared with a midi track using the same channel : CC48 is sent on channel 2. If all audio channels are shared, or if they are Off, nothing is sent. Same rule as AUTO setting in MIDI SYNC page. It doesn’t correspond to AUTO CHANNEL as on other Elektrons, but to the lowest audio track channel (not shared). Confusing, isn’t it ? …

Discarded option as i am monitoring with a MIDI Monitor tool for Mac

So @huuh what about your midi tracks ? They can block/change crossfader midi channel.

Didn’t checked yet. I will do it tonight

[huuh]

I don’t get the point sorry

If I am using the same MIDI channels for MIDI Tracks & Audio Tracks, the crossfader should work on Ch9, no ?

[sezare56]

@huuh

Ch9, no ?

No. Nothing is sent in that case.
Tested a while ago.
Not +1, but lowest channel not shared…
If all channels shared, nothing is sent.

Crossfader and scenes are sent on the lowest midi channel of the audio tracks not shared with a midi track channel

Got it now

Then the solution for me. As i am using the first 8 midi channels for midi tracks, I assigned for the first audio track the channel 9

As it is the first channel not shared the crossfader midi is registering there

Thx so much @sezare56, really appreciate it!

@huuh

really appreciate it!

I am glad I didn’t make these boring tests only for myself !
