Random octave changes

[sak-rwsd]

I really like the Melodic Probability device in Ableton (except for the fact that my notes become invisible whenever I close shop and come back to the project).  In it, you can dial in a percentage for octave changes for a given note.  I find it can add some life to a sequence, while also maintaining some melodic structure.  Is there any way to do this in NERDSEQ?  I’m mostly interested in doing this on MIDI tracks at present, sequencing some hardware synths, but also would be good to know how to do on modular tracks as well.

Not sure what I'm proposing is what you look for, but here I go

I haven't actually tried it but my guess is it should work similar to:
- create a table that transposes 12 up or down
- add FX PRBT with the desired probability

You could also use FX TABL to start a transposition table. Together with PRF1/PRF2/PRF3/PRF4 you could attach a probability to it. If I understand it correctly that way you could select with preselected probabilities between up to 4 different tables and "no transposition at all" (i.e. 5 different ways to transpose).

When you wish to transpose the rest of a sequence until the end of the current pattern you could us FX BASE. Together with PRF1/PRF2/PRF3/PRF4 you could attach a probability to it. Again you could thus select between 4 different transpositions (plus "no change")

Kind regards,
Michael

Nice, I was thinking the tables might offer a solution, but alas, that won’t work for MIDI tracks yet (I believe!).  Thank you (I will try this out with some of my modular voices in the interim)!

Yeah, no midi tables so far.

But the basenotes should do the job. Put a +12 or -12 basenote in the FX and enable probability for like 50% on both FX. That should bring you the chances of having the sequence in all 3 octaves.

Let's assume we have the following setup:
FX1 == PRF2 50
FX2 == BASE +12
FX3 == PRF4 33
FX4 == BASE -12
What happens when both FX2 and FX4 are triggered?
Will that result in no transpose (i.e. are the transpose FX cumulative) or overrides the later the former?

If the later transpose overrides all earlier ones then the above setting will result in 33% -12, 33,5% +12 and 33,5% no transpose.

Should it be cumulative then I'll have to redo the math

Kind regards,
Michael

I'll keep the math for you :-) But indeed if FX4 is being executed, it wins, doesn't matter what happened before.

Thanks so much - this works good enough for my purpose. Never used base notes before! I have to be a bit clever about finding space as I have multiple mono-synths being sequenced out of a single MIDI track (thank you!) and need to set the base note to 0 before and after if I only want the octave changes on particular steps. I’m already using the FX for other FX and the track cv/trig/mod outputs. So a little puzzle work, but I find that fun, once I’ve gotten a hang of how it all works a bit more. I think base note changes affect all MIDI notes/channels across the particular step, but that’s ok - adds to the variation so far. Would be nice to be able to target a particular note, but I guess the more common use would be to transpose whole sections.

P.S. I’m loving being able to use Envelopes & LFO’s from NERDSEQ to Ableton for fader and other parameter control. Probably a basic MIDI pleasure here, but I didn’t expect to be able to control my DAW (and MIDI-compatible pedals) from my modular (which keeps it a bit tighter, and interwoven with my sequences I find).
