Trying to sequence source notes for my sub37’s arpeggiator. I have MIDI set up properly. MIDI in/out work. I can physically play the arpeggiator via the sub37’s keyboard and other keyboards connected to my rig, but when I sequence whole note chords on the octatrack, the sub37 arpeggiator only runs for 2 notes and then stops. Note length is set to inf.
If I turn sub37’s arp off, I hear the sustained notes of the chord. If I record a performance playing the chord progression on the sub37, octatrack records the arp pattern from sub37, not the notes I played on the keyboard. But, those notes sound gated too. I thought it was a pattern length/resolution issue, but I looked at that already and it should be fine. I’d rather not record the arpeggiator sequence from octatrack, as I can have a longer arpeggiator pattern by sequencing sustained chords instead.
I’ve tried different presets on sub37. All behavior without arp is as expected. Local Arp behavior in sub37 and with octatrack’s arp are as expected, everything is great except when triggered with steps on octatrack.
I could use the octatrack’s arpeggiator, that works, but I’d like the arp pattern to stick with the synth preset, not an octatrack pattern.
Yes there are independent transmit and revive MIDI channels. ARP doesn’t appear to have any settings. There’s a clock setting where the arp can send clock, but that’s already off.
Yes if I change the out channel to something different than input the problem goes away, so there is clearly messy data in the pipeline somewhere. MIDI feedback loop.
I think I’ll have to use my midi controller to play anything into the sequencer for sub37 arpeggiator stuff. It’s set to my auto channel and its a major player in the rig anyways.
Im gonna try also setting sub37 out to my auto channel.
Thanks for the reply, it got me to dig a little deeper…DirectConnect seems to be friendly with Sub37 so far, but I finally found how to turn off arp from sending MIDI which was the real problem. Sharing here in case someone has a similar issue.
In Sub37, the is found in the global menu, under Seq Options > MIDI output. If set to SEQ, this sends arp MIDI. I set to Keys and now its doing everything I hoped for! Phew. Kind of a weird place to put that, but there’s many other parameters for the arpeggiator that I never knew about so it makes sense for it to have it’s own menu. Wish they had used ‘ARP OPTIONS’ instead of ‘SEQ OPTIONS’, but that’s pretty much the one bad thing I have to say about this synth, so I guess that’s fine
Glad to hear you figured it out. I agree the naming is a bit confusing… otherwise the Sub37 midi implementation is exhaustive, I knew it was somewhere (I thought it could be the “panel off” param, or something) (I didn’t look it up because the studio is still not powered up due to heatwave/no airco conditions… )
