Parameter slides with modulo TRC

I have unexpected behaviour when using slide trigs with trig conditions, now I know that % trig conditions won’t work because the OT can’t predict if the next trig will be positive or not, BUT I have had some success with other trig conditions, however the behaviour is erratic.

Here’s an example describing how the pattern is set up with a 32 bar sample (pattern scale set at 64 step, 1/2 scale)

1st trig with slide trig and TRC 1:4, Filter base locked at 0

16th trig with trigless lock and TRC 4:4, Filter base locked at 64 (or any other high value, this is just an example)

The pattern will repeat 4 times before the sample loops. The desired effect is a smooth sweep of the filter base across the full 32 bars, however when played the sweep occurs abruptly (across the first 2 cycles) then finishes very slowly across the final 2 cycles. It sounds as if the sweep is exponential rather than linear. Interestingly, if the trigs are set to 1:2 and 2:2, the sweep occurs in a linear way, it seems to be longer sweeps that are affected. Also, if I program an LFO and p-locks to do the same task, I get a smooth linear sweep.

Ive contacted support and they say that slides can work FROM a locked TRC but not TO a locked TRC. This makes sense but doesn’t explain how Ive actually got it working. Is it just pure fluke that it sometimes works?

Ha! I was getting all excited about this feature, then support said its not actually a feature :thinking:

Interesting question - I remember posing a similar one for intervening TRCs which don’t occur - is expected behaviour that the slide looks for a valid end point (how can it predict?) or steps to next real trig … something vaguely like that iirc … curious to explore this later to see what’s what so that you can try to predict what will happen in related scenarios … I may be confusing with mute trigs (A4 etc) in terms of what should happen with slides when mute trigs are active, need to look this out

I disagree with the reality of the summary quoted - it is currently possible (as you’ve noted) to Slide from a Locked TRC and TO a locked TRC

e.g. with two long notes on 1 and 9 where 9 has a 1:2 TRC and a parameter locked difference to 1, the long note on 1 will always slide to the value locked on 9 - this happens whether the trig on 1 is a TRC or not and whether the parameter locked value is on 1 or 9 or both - the slide will engage, you just won’t trigger the env/note of 9 every time, but 1 will slide to the setting of 9 - so you can slide to a TRC

(tested on A4, but sounds like this is the case for you too)

[you can’t slide to a muted trig on the A4 fwiw]

Hey, thanks for taking a look at this!

I’ve been messing about with this again today but still can’t figure out the ‘rules’ properly, its a little erratic. I can get nice sweeps across 2 pattern cycles but it goes a bit wonky across 4 cycles.

Whats cool is you can add more TRCs in to the sequence and it does actually figure out the right order even if, say a 4:4 trig is placed before a 2:2 trig in a sequence, if there is a slide occurring then the 4:4 trig doesn’t interrupt it until it should on the 4th cycle. Nice for triggering new slides with different values!

may well be different on the OT to my looksy on A4, will look back at this, but a parameter slide should only slide to the next trig sequentially … it shouldn’t factor in the scheduling of modulo values - but maybe the erratic thing is because OT is following a different path, maybe sliding to a TRC doesn’t work as proposed but it’d be odd for there to be different behaviours between boxes

I think maybe it was working ok with multiple TRCs because I was using trigless locks to alter the parameter slides. Its certainly not perfect but can have nice results sometimes :slight_smile:
