LFO to slice - how to?

Can anyone give any pointers please as to how to set up an LFO to change sample slice?

I have a 16 bar, 4 slice sample, that I want to change slice every time the pattern loops after 4 bars.

I think I have sussed it but then it only triggers for example the 1st and 4th slices. I am trying to used a custom LFO shape for this.

I have tried just about every thing I can think of but am not having any joy.

LFO´s... what are in them?
#2

did you try modulating that lfo"s depth with another lfo?

#3

No, but I think I have it sussed now.

It was just a matter of finding the right values for speed and depth in LFO set up.

I’m making notes of the values now as I work it out!

Glad to see you worked it out - thought I’d add the way I’d do it, if it gives you some pointers:

So you have a 4 slice loop.

LFO set to hold (so the LFO runs free but for the duration of a sample trig the value stays at the same value - meaning that the slice the LFO ‘selects’ won’t change until the next trig)

LFO depth set to random for random selection of slices, depth set to 4 (4 slices)

Here’s a handy cheat sheet for LFO speeds - from this you can determine what speed you want to set the LFO to for it to sync with your sequence length. Doesn’t really matter with a random LFO, but for ‘cyclic’ LFO’s it’s handy.

Made for the Monomachine, but I think it works for the OT, too. http://www.elektron-users.com/index.php?option=com_docman&task=doc_download&gid=601&Itemid=30

Thanks for the info and download link. I have an MnM too so it will be useful for that as well.

I think I am reasonably happy with the basics of what I was trying to achieve.

However, if I had a 16 slice sample, is there a way I could get to select which range of slices would be used? For example, 1-4, 5-8, 9-12 and 13-16.

The LFO designer comes to mind. You could make an offset lfo (the entire LFO is above the 0 crossing), which probably would allow you to do this type of selecting?
Haven’t tried it, but I see why it wouldn’t work.

Hi. Succeeded too but, the lfo don’t start everytime at slice 1 when I start the sequencer. The lfo is not reseted to the first value. Any idea ?
Wave T1 : 0 2 4 6 0 2 4 6 etc…
Trig Hold.

#8

If slice locks have already been applied to trigs, is this overridden by the lfo or are values combined? Can’t seem to tell

#9

The lfo modulates plocked values, in a bipolar way, depending on lfos.

Ex : a plocked value is 32.
With a square lfo with depth 2, the results will be 30 and 34.

Hierarchy :
Parameter, plock, scene lock, lfo.

Answering myself 4 years later! :smile:

Yes. SYNC TRIG of course!
Reset, not reseted.
