Octatrack Tips & Tricks (OT Tips)

How to set up 2 EQs on different tracks to be controlled simultaneously from one encoder page using MIDI loopback.

Use case: For :elot: DJing (and many other things). Say you are forced or want to DJ on your OT. You have no DJ mixer available. You want to fade out the bass on the currently playing track, while fading it in on the incoming.

Hardware:

  1. Connect MIDI cable from OT’s out to in.

Software:

  1. On track A (in this case: audio track 1), insert DJ EQ on slot 1. On track B (i.e. audio track 5), insert DJ EQ on slot 2. The other slots on track 1 and 5 should stay empty.

  2. In MIDI mode, choose a channel and set it up in MIDI control setup. Set as follows:


    This is the CC setup on the MIDI channel your encoders will be sending from.

  3. Set the MIDI control channel (on MIDI playback setup page, ‘MIDI note setup’) to, for example, 4. Any channel will do, but it has to be the same channel as in the next step.

  4. Go to MIDI: Channels (FN+Mixer). In this case, set tracks 1 and 5 to MIDI input channel 4, as that is the one chosen as the MIDI control channel in the previous step. Set track 4 input to OFF.

  5. On your MIDI control channel’s ‘Cntrl 2’ page, the top row of your encoders controls audio track 1 EQ, the bottom row controls track 5 EQ. Bass gain is on the left, mid in the middle, treble on the right.

Yes, this suprised me too, in another context:

possibly this extends to MIDI notes as well.

Just noticed this, great idea! Getting different modes I’d already thought of on my own but I was missing harmonic minor and I probably wouldn’t have come up with that idea any time soon.

Internally recording fills to Flex tracks is fun

Super easy, accurate CV sync to clock Volcas, Pocket Operators, Modulars etc (This will only be useful to people who don’t normally need the cue out)
—Go into control >> Metronome settings. turn on metronome (Active). Set Main Volume to 0 and Cue Volume to 28, or thereabouts. Adjust time Sig as needed, the Monotribe is 4/8 for instance. Patch cable from cue out to cv sync in on your device. Yeah!

Somehow last night it dawned on me that one-shot plays free midi tracks could give me a bunch of fills to send to my Rytm… :slight_smile: (using the lowest midi notes to trig Rytm voices using only one channel)

I recently (re)discovered this, and it’s great.

OK so here’s a handy dandy chart to easily use any of the seven modes in any key…

(Bb=A#, Eb=D#, Ab=G#, Db=C#, Gb=F#)

Just find the mode and key you want on the chart and set the arp to the major mode in the corresponding key shown on the left… :sparkles::monkey::sparkles:

-I copied this chart from the Internet, It shows several flat keys at the bottom left, on the OT the key can only be set in sharps so I listed the equivalent sharp keys at the bottom just in case…

Remember to check out the personalize menu. There’s some useful options to customize button behavior and some other goodies. I’ve toggled quite a few of them to better suit my workflow… :monkey_face:

Sorry but what is the “Master affectation” ?

Thank you!

This isn’t a trick as much as it is a tip about file management:

If you’re using single hits as drum samples, you’ll find that it’s easy to take up a lot of static/flex spots with just hits. Something I’ve been doing is to bring all of my drum samples into a DAW and to put all the kicks on one track, snares on another, etc… I render each track as a single WAV file, then I bring them back into the OT and assign slices to each hit. This way I have one sample slot for all of my kicks, one for all of my snares, etc. It saves space on the slot list, and actually makes it easy to compare hits, as they are slices that can be played quickly via Slice Mode. If you don’t have a DAW, you could always resample your hits onto a single track and slice that track.

I’m sure this has been utilized by a lot of people, but figured it was worth mentioning for those that haven’t considered this approach.

Yeah this is something I keep forgetting to do. I’m not sure if I’d group all of my kicks, etc but I do have a lot of single hit percussion samples that I tend to use monophonically together in a track. I just never think to render them all in one file and then slice on the OT!

Yes I once took the time to organise 64 slice wavs each of kick, snare, etc. But also taking care that the slice numbers matched up in terms of kits - so for example slice 34 matches up through the various sliced slots as being from same kit.

Then I can use the fader to scroll through the kits live, by having slice 0 on scene A and 64 on scene B for all tracks with sliced drums

I thought it would be good for auditioingg but the changes you get with the fader going through kits on the same rhythm are often really nice so that’s more how I use it now

And there is a very useful free tool to create your slices very fast : Octachainer, by @Abhoth :

And of course Octaedit by @Rusty, with its chainer module :

My humble OT tip.

I have been trying to come up with a really tight xfader curve for scratching with OT. Now there are several methods for this but I think I finally figured out the best way:

Set up a delay fx for the track you wish to cut with the xfader. Configure the delay to do echofreeze. Now make that echofreeze output silence with a very short delaytime. Set up a scene which activates the echofreeze and Bob’s your uncle.

While I find this method produces the fastest possible cut with the OT fader (MIDI CC value change of just 1 unit for opening and closing the fader!), its still more of a ”scratch switch” type of cut, not a fade, so results will wary. A real cutting xfader will still produce more musical scratches. But this trick is neat for cutting up beats and such!

I have to try this. I thought about you and your OT’s crossfader best curve quest when I found another trick in order to have direct 100% level with crossfader (1 CC value too) :
Plock Thru machine Input AB / CD values.
Instant cut / on.
I ended with recording A and C or something for stereo, don’t remember why.
And it is clicky !

Apparently you found a better solution, maybe plock Inputs can be used for other purposes.

That tip is really good ! :thup:

I didn’t know delay’s VOL doesn’t work with LOCK I. :thinking:
You can also keep a regular 48 time setting with feedback so that when send > 0, dry sound only, and with send = 0, delay only.
That way you play the sample normally, and it has delay only when you cut it with the crossfader.

Could you remind other methods, or link the concerned thread ?

Might not be big news but I just soloed an OT track for the first time… Never came up before…
Maybe some of you are with me, so it’s cue+trig while in the mixer or quick mute mode… :smile:

Also there’s a handy group mute/unmute using func+trig in those modes…

You have got to be kidding me. And here I was thinking OT and me were already close :joy:
