I see what you’re saying and while it wouldn’t be quite the same, if I wanted to do that with midi I would probably use the elektron sequencer and program my trigs using all the same note for ease of input and then turn quantize to the strongest setting and then just overdub my desired notes quantized in live record mode, either one at a time or however it’s comfortable for you.
Just to explain a little better, let’s say your track note is the equivalent of middle C or whichever note you want to start with. Program your trig pattern into the octatrack in the same way as how you’d program the pattern of rim shots or whatever you intended to use to trigger the Roland note sequence.
Now that the single notes are in the sequencer you could leave it at the same tempo if you’re comfortable with that, or you could turn the tempo down you know, 10 bpm or whatever seems like the timing is slow enough so you could enter all the notes in one go if you wanted to, or you could do it one note per cycle through the loop or whatever.
As long as you have quantize enabled and you’re in record mode, it will continue to play your trig sequence which will be currently all the same note, but the elektron sequencer won’t double up the notes (it’s not polyphonic after all), it will replace a note with any note played over the top of it. I’m assuming you’re using a midi keyboard for this, but if not, you could use chromatic mode on the OT.
Just play the note you want, try and hit the desired keyboard note close to when the trig hits, and quantize should replace that note in the sequencer with your note. Do that until all your notes are entered into the sequence.
If you found it distracting to do this with overdubbing notes, i can see maybe doing it with 2 tracks, something like a rimshot or a clap on an audio track or basically something that acts like a guide for the trig input (you could also adjust the tempo down 10 bpm or whatever to make input more simplified) and then a midi track for the SH01A using the same concept of quantized input entering one or 2 notes at a time, and with the click track as a guide it will both tell you if the note input is off grid and it will also prompt you to enter the notes in time with the trig sequence.
I realize this is significantly different than the method you described but it’s at least an option because if it were me I’d be trying to avoid using the SH01A sequencer altogether as it’s a complicated way of getting from point A to point B using the OT sequencer sending audio trigs just to trigger the notes on the SH sequencer.
I mean it’s a workflow, I get that, but it seems like unless you’re really committed to that cv / gate workflow, there are equally complicated or possibly less complicated ways to go about this with midi. I literally just thought of one thing, I’m sure if I thought about it long enough I could come up with something else but my point is just that if you can’t easily accomplish what you wanted to do and use audio trigs to trigger the pattern on the SH sequencer, then you’re already putting in more work than whatever you intended.
If you still need help getting the audio triggers to work you could try an 808 trigger or a sharp rim shot and you want to make sure you’re connecting to the trig input via mono TS cable as you’ve been doing.
SH101 is actually a bit picky about what kind of trigger you send it but I think SH01a should be a bit less fickle, however you’d just have to try it. Triggering 2 notes sounds to me like the sample being used as a trig isn’t fast enough, like it must have a lingering transient or something. You could test this by slowing down the bpm and sending the trigger sequence and see if it plays as desired, then slowly ramp up the bpm until the double triggers start and adjust the amp envelope or compressor settings until it triggers only the single notes again and then adjust the tempo up one more time and see if it stays in the pocket or not.
Anyways sorry that’s all the time I have to think about it right now but we can touch back on this later if you’re still having issues.
Good luck
I will give it a go like this, but I’m more into the “old school” way of sequencing notes in a synth. Anyway, i will also try different ways of triggering with different sounds/transients/cables etc.
