This idea occured when thinking about my upcoming A4, but I’m currently trying with the OT, without success. But it should be the same on any box.
If you place a trig on the first step of track 1, with a probability of 50%, and a trig on the first step of track 2 , set to “not NEI”, then you have an either/or situation, where only one of the 2 tracks play. Cool.
But is there a way to extend this to more than 2 tracks with the currently available Trig Conditions ?
yes, but not directly referencing the track 1 trig - you can have a cascade where track 3 is a not nei looking at track 2 … so 3 = 1 in that case
Yes, but I guess @chapelierfou would want to alternate at least another track, hence 3 different trigs, not played together. I already tried without success.
With OT, on one track what you can do is have a sample with recorded silence before, so that you can cut it silently. (Have to test again)
Yeah, that’s what I experience. Not a “cascade” then !
Yep but the original idea is on the A4 :
4 tracks, same sound in all tracks, but 4 different sequences, then the result would be random fragments of each 4 sequences, but each one at the correct “place” in the bar. Structured random.
If you know Ableton and random follow actions with “legato” enabled, you’ll know what I mean.
Or a bit like the “jump” pattern mode, with four patterns and only one track .
Yes I see, I did it with 2 tracks recently.
On 1 track you can make 2 different melodies btw. But you cannot record it live, and it doesn’t solve the problem of alternating more than 2 tracks with TRCs.
For A4 I thinking of chords that would block notes because of poly limitations, not sure if it’d work.
Random mutes/solo would do the trick.
Ah direct jump too indeed. And direct jump can be done with midi notes with multi map.
What do you mean ? The FILL pattern would not work here if it’s what you’re referring to.
In my case I was thinking 4 monophonic tracks. Or do you think that Elektron specifically made it not possible to prevent from happening in polyphonic modes ?
It works with 8th and microtiming.
Melody 1 on step 1, %50
Melody 2 on step 2, /PRE, -23 microtiming
Melody 1 on step 3…
Etc…
Limited resolution, you can use scale x2.
I have to try, I was thinking of chords with notes you can’t hear (too high or too low), that would block other notes…
Not ideal anyway.
Something simple : random arp on one track ! 
Eventually record your melodies separately, then record them on 1 track (from another sequencer, midi loop back.
Midi loopback would work I think. Send 4 tracks to another one with random arp.
Nice idea…
If I get it correctly, you send 3 other tracks to the first track. Track 1 has a random arp so it freely choses 1 of the incoming notes.
But still, no different lengths for notes, no “groups” of notes (the choice would be made for each incoming note"), etc…
I think 4 midi tracks are necessary. CV or Fx track can be used (you can copy/paste track 1 for instance).
But yes, as you can’t plock arp parameters, it is limited.
That is to say ?
Like 3 consecutive notes that would always occur in a row.
I don’t think a per step random choice is super musical. I prefer working with small “units of music”.
I gave it a try with A4. No need for arp with the midi loopback stuff, if the track receiving midi note is mono or unison (not poly). I made 4 tracks with different melodies, set Probability to 50% for all. Seemed interesting to me.
You can set 2 tracks with NEI, 2 tracks with %.
Sampling with OT, random slices !
(In order to keep original melodies and stay in time, you need some megabreak of doom, or randomize slots with external midi.)
No need for midi loopback, Unison suffice. @avantronica will laugh at me ! 
I made a test with 4 tracks with Probability 25% and Unison. No midi loopback.
Same with 2x2 NEI
Lowest tracks have voice priority (track 1 first). Maybe you can take advantage of that…
(Sorry for smartphone mic recording.)
So @chapelierfou what do you think about lowest tracks priority ? I guess you’ll figure it out better when you will receive your A4 !
In Unison mode, I think using something like that can be close to what you wanted to achieve :
Track 1 : 25 %
Track 2 : 25 %
Track 3 : 50 %
Track 4 : /NEI
(On a same step position, track 1 have the highest priority, but its notes can be cut. Tracks 3 and 4 are playing continuously (alternatively), so they potentially cut notes; so it’s not perfect)
It’s a bit hard to tell what’s going on from your example (but they’re super helpful though!), I’d have to put my hands on it to really figure it out I guess. My A4 is on its way, so hopefully on Thursday !
I’m not sure how the Mutes work on the A4 (trigger or audio ?) but maybe there’s a way by muting track groups ?
Anyway, thanks for the help !
No problem, interesting subject for me too !
Trigger mutes, so yes, there is something to do with track mutes, maybe with midi processing (mutes are per channel).
Imho the simplest and closest seem to alternate 4 patterns with Multi Map and its Direct Jump feature* : a random arp on 4 notes played from OT and you’re good (eventually CV/FX tracks with midi loop back and prob, unfortunately no midi arp).
*Multi Map has a specific Direct Jump setting (CHG MODE).
foiled again… direct jump doesn’t work when multimap is triggering the patterns - patterns always start at the beginning when triggered from a MM key 
[edit] ohhh you can change its mode per zone with CHG MODE
Yep, that’s what I meant. 
At first I wrote Multi Map and Direct Jump, I changed to “its”. I’ll edit again…
