Octatrack Tips & Tricks (OT Tips)

Search a bit…:wink:
You can also use square lfo with speed = 0, faster to set up.
Can be used for fine tuning (0.2/127 precision), slice offset to change a drum kit…

Nice! Yeah - I would not have found that. :slight_smile:

Great tip on your part too. I just tried it. IIRC, it is invert square wave for going up; square wave for going down.

I did this with my faderfox (UC-4) buttons to have my master-track-delay allways under my fingers. I setup the UC-4 buttons to the same delay time the OT trig-buttons are set (1,2,4,8 etc.) In use though it will result in more ‘glitches’, you can here the delay switching to another time. While using the OT trig buttons for that you don’t here that.


Accidentally discovered this last night…

Selecting a sample in the SRC SETUP sample list and pressing [FUNC] + [LEFT]/[RIGHT] will load the next or previous sample from the directory the original sample resided in.

I thought it was helpful and don’t see it in the key command summary so, I thought I’d share.


Yeah, that’s very useful. I usually fill my sample slot list so that I always have a bunch of kicks, snares, hats, claps, single cycle wavs etc in row. With [Function] + [Left]/[Right] I can easily try a different samples on a track.

Not sure if this is a bug or a tip but you can use reverb and delay together…

  1. Use dark reverb on FX2 , set all your parameters.
  2. While still on FX2 just copy that page, once copied, select FX2 to none(just remove it) this one is important as having two reverbs will create some wired unpleasant pops…
  3. Go to FX1 and paste the previously copied page, you won’t see anything but you will hear the reverb.
  4. Go to FX2 and choose delay.

Not sure how well the machine is optimised to handle these two effects, maybe it’s fine… I don’t know.

Moderator edit - to avoid two threads filling up with identical discussion on this …

reply on the thread linked below please

in all likelihood, this may now be fixed as you’ve drawn attention to it

You can arm individual one shot trigs in grid record mode by clicking them. I didn’t see this when I searched the manual but may have missed it. It was fun in use on a hi hat pattern so I thought I’d share.

In fact it arms all one shot trigs of the track. Clicking on one suffice to arm the others. Maybe safer to use YES or FN+YES. :wink:

I could have sworn it was only arming the trigs clicked on. I’ll have to double check.

To stop the sequencer without stopping recordings, press PLAY (pause). You can stop recordings by pressing STOP afterwards.

Usefull for a “long” internal recording, to stop the sequencer and continue to record fx tails at the end.

(Probably written somewhere?)


Does that work for recorder buffers recording any source? Or just internal (T -8, cue, main).

Yes, I edited, it was an example.

Is there a shortcut for ARM ALL? (for one-shots)
Ive disabled stop-stop, as Im so used to using this for reset transport/ all -notes-off , so this led to losing recorder buffers contents (by unwanted re-recording) … so i wanted this to be more explicit.
similarly, Ive disable yes/no, and use f+yes/no.

those that have had OT longer, have you disabled these? or are you just more careful with how you hit play/stop…

With the rec light on pressing yes arms one shots on the track. And with the rec light off pressing yes arms one shots across all tracks :slight_smile:


you don’t have to put on the red light,
(if you want to arm them all)

Double stop also send all set Control Change.
I used it for Arm All but I may disable it as I don’t use it anymore.
I may use Fn+Yes too because last time I armed by error.

Arm All also arm track recorders one shots.

Arm don’t arm track recorder one shots if you’re not in the rec setup.


humanisation/round robin trick I just thought of

  1. get a snare, put it every 2-4 steps. slightly vary the volume of each one. not too drastically. 1/2 track scale.
    2.record the track with a recorder trig, 64 steps
    3.save to slot and put sample on the track, turn on slices
    4.slice into separate snare hits leaving small slightly different amounts of space at the start of the sample. bigger gaps=drunker hits
    5.random LFO to slice number
    6.clear pattern and play away

haven’t tried it yet but no reason it shouldn’t work


Yes, this works great. I’m using this method since I got my OT for various use cases:

  1. sample accurate micro-timing (much finer than the few possibilities given by microtiming itself)
  2. slowly moving swing (using a very lowspeed triangle LFO)
  3. drunken drummer (as in your example - using a random LFO)
  4. for specific probabilities not possible with trig conditions: for example use 64 slices, but only 17 containing really a sample, but the rest silence (17/64 chance)
  5. phasing effects: using two tracks each playing a different slice with start points just a few samples apart (great to modify live in the AED by moving one of the start points around).

Of course, the probability use case as hinted at in (4) doesn’t need that much empty slices. It’s enough when the last slice is empty (for example slice 18), but the LFO uses the complete range of 0-63. This way it will trigger in most cases the last slice (again 17/64 chance that the sample will play - but uses much less memory).


Interesting! Personally I usually prefer steady things, but too much sounds triggered at the same time can be problematic!

I recently used the opposite : different ends for tuned slices for tuned sampling!
If I want to make a tuned synth with incoming signal, whatever the tempo is, I use different slices, all placed at the beginning of the sample (yes, possible).

Ex : C = 674 samples, G 450 samples.
Slice mode.
Change LEN=TIME for octaves up (128 / 64 / 32 / 16 / 8 / 4 / 2 / 1

Weird example, crossover between incoming signal and realtime sampling, pitch determined by slices. :loopy:

Number of samples.


Nice! I wonder if the slice length is in all cases enough to get a strong fundamental to appear (almost?) independently from the incoming signal …
