New OT MKii with LFO questions

Man, Octatrack!!
At 4:00 this morning I realized I had been playing with this for nearly 16 hours straight… So much fun, but still so many questions.

Yesterday I discovered why my loops weren’t syncing properly (48Khz vs 44.1Khz). Learned how record trigs work, messed around with scenes, and got Midi going. Oh, and discovered the beauty of Cue send.

LFO is doing my head in though.

I have read a few posts here (Merlin’s guide, etc) that describe how sample start and LFO work, but I just can’t seem to get it…

I recorded me counting from 1-64 and then sliced this into 64 slices.

I then added trigs on the 8th notes of a bar and set them all to slice 32.

I then set the LFO to control the slice, and set the type to random, and put depth to 32 (going up or down 32 slices?)

However, I just couldn’t get the random samples to play high or low enough. I kept getting way to many “ones” and not a single 64.

How would I set up the LFO so that sample 1-64 has a possibility of being triggered by the LFO.

Any help would be appreciated.

Also, is it safe to assume that the LFO on the OT can’t change the sample in the sample pool like the Digitakt can?

Thanks all.

Other than depth (essentially the range) on the LFO I am not sure. Speed would dictate how quickly the LFO sweeps through the depth. Curious as well. I would like to know about the pool question. If not, could make for a great pair with the OT. I am sure some OT vets have a workaround hopefully :pray:

Random is unfortunately not that random in the world of programming so you will hit 1 more often than desired.

I believe you just need to increase the depth. It’s not a 1 to 1 ratio in that setting the depth to 32 makes it go +/- 32 slices. In fact, I think you would need to put slice 1 on those trigs, set the LFO to “Random” and set the depth to max. That should have a chance to select any of the 64 slices.

Also, I don’t think you can use the LFO to select a different sample from a flex/static slot. You can, however, use sample locks. Similar to a parameter lock, push and hold the trig you want to use a different sample on and use the Level encoder to select the sound you want to play on that step.

That’s right! You can have each trig pull from a different sample (be mindful of RAM with flex machines) and the LFO would still apply. Good insight :tada:

Thanks for the quick replies.
I was under the impression that depth was cyclical (both up and down) so I had to set my samples at the middle slice so they could go both up to 64 and down to 1.

Can sample locks be modulated via LFO or did you simply mean that it was a way to access different samples at different stesp?

I always thought the ability to change the actual sample with the LFO was a cool feature on the Digi… but I already enjoy the Octatrack more :slight_smile:

Yea middle slice makes sense. The DT is special but the OT is more special :laughing:

Instead of putting the samples in the flex/static sample slots you can put them in a sample chain and use the LFO to modulate the slices. Look into Octachainer to assist with making sample chains on your computer.

Here is cool tutorial on octachains without a computer:

Thanks for the info @d4ydream :slightly_smiling_face:

Thanks. People have been suggesting that, which is where my experiment with this started… Is my example of speaking 1-64 a similar concept, or is it slightly different?

I was trying to seeing if there was a way to consistently / randomly use the LFO to modulate the sample chains, but thought it would be easier to test a d experiment with numbers than hi-hats or kick drums :slight_smile:

Oh oh, new track types!!
Family are going to wonder what is wrong with me if I disappear for another 10 hours while I explore these… probably gonna happen LOL

I think it sounds right so far. Have you tried different lfo speeds?

May be the start point of lfo? If it always starts at 0 then of course it doesn’t change. Check lfo sync.

In slice mode, you have to multiply lfo depth values by 2.
Slice 1 > Depth 2
Slice 2 > Depth 4
Etc…

Thank you sezara56.
Do you mean that if I want to cycle through 64 samples I would need 128 as the depth? Would I set my trig locks to slice 64 or 1?

Thanks again.

Start = 32 (slice mode)
Speed / Multiply depends on sample length.
