Octatrack - Feedback Loop - Dub like king tubby - for real

Heath · 2023-12-30T01:28:45.300Z

It’s old tech, but so is pretty much every vintage synth. Still sought after.

abluesky · 2023-12-30T03:17:33.837Z

Yeah and I don’t buy vintage gear. Lots of problems and I don’t like the time sink.

CUE R → Octatrack Input C

------------------ TRACKS ------------------

CHAIN 4 CHANNELS:
T5 THRU → IN C comes here

You can record CUE internally, and play it with a FLEX instead of a Thru. That way you benefit from SRC parameters like pitch, rate, len, retrig…

impbox · 2023-12-30T06:12:09.921Z

Yeah this is amazing! Thanks for the idea! I made an alternative setup using separate buses for left and right so you can have pingpong with different lengths and different effects on each side.

T T: C panned right, D panned left
N N
N N
T M: input from A B or any other static or flex sample here.

That was very cool. I love feedback.

YouTube video of it working

Hey, what was the thing in your left hand in the video?

And thanks for the write-up. That was very clear.

Hey, glad you like it!

ah it’s nothing just a dumb cigarette thing… irrelevant

That is true, 2 reasons why I chose to go out with a cable:
a) My incompetency when getting to the record functions of Octatrack, haven’t yet found the time to explore and add it to my thoughtflow Also, I mainly use the Octa to perform live and I haven’t really felt the confidence to use the record functions on stage, but again, haven’t spent the time…

b) I deconstructed the main idea of the dub loop so I blindly/dumbly connected the output to the input but another aspect that led me to this is that you can still connect your favorite delay, filter, chorus whatever in the loop. So with the cable, I think there’s more freedom instead of staying 100% in the box.

But yea, of course if you want to stay 100% inside Octatrack this makes sense! Great idea

Umm that’s a good idea but I didn’t quite get the routing, could you explain it a bit more?

impbox · 2023-12-30T12:27:51.324Z

Basically the left tracks are for the left feedback and the right tracks are for the right feedback.
T4 is for input or sample playback.
T8 is master.

It works pretty much the same as your setup.
T1 listens to input C and pans it right so next loop it goes to the opposite side.
T2 listens to input D and pans it left.
The neighbour tracks are just for FX and T3 and T7 send the feedback back to the cue outputs and to main output too so you can hear them.

That make sense and I do it sometimes.

Yes, I especially like to use analog distortions. But you can also use Recorder + Flex instead of a Thru track.

With sampling the feedback loop can be repitched, reversed, so you can get very interesting results like these :

Some other feedback ideas.

Feedback loop ideas thread Octatrack

CUE feedback with comb filters, recording ABCD for noise, nothing plugged, no samples, one bar pattern moving crossfader.

Anyway, thanks for feedback !
Feels like I gonna kill my ears today…

Ah I get it now, yea great, I maybe would also mono that so that you use the different timings in the same channel it’s dub after all, mono is still good!

Hahah this is sick! I have to find the time to dig that, very very interesting!

Yea, for no-input, what I figured is that if you use T7 compressor from my setup and you just smash the nothingness you get a lot of Octa noise while staying in the loop! (utilizing all the modulations etc…)

Haha, take care!

Thanks for the great ideas! What USB to midi -host you are using for the LaunchControl and does it get it´s power from the host?

mpanalog · 2023-12-30T12:54:42.668Z

Hey!

I’m using this:

Kenton Midi Usb Host MK III

DescriptionYour USB device is plugged into the USB MIDI Host mkIII instead of into a computer. It provides MIDI In & Out sockets for USB MIDI keyboards and controllers which have only a USB B type socket. For example, used with a USB-Solo, it...

It needs external power! Has never failed me fwiw

If you put 2 cables between CUE LR and CD, your setup is stereo.

Interesting, I used that principle to get a true stereo reverb (OT reverbs sum LR before processing, as most of reverbs).
But I prefer to keep a single stereo bus.

Yea sure, I mean in case you don’t want the ping pong (which I kinda find gimmicky to be there all the time) you can sum to mono and just have the different timings on the Center channel. I might not be right cause I didn’t set it up to see how it works, just an idea. Now that I think of it though u can just not pan, anyway, I’ll have to test it to be sure.

Example with CUE recording + Flex. Basic loop at the begining, then feedback loop.
T1 : Drums
T2 : Chords

T6 : CUE rec + Flex, pitch +12, lfos on filter, balance, delay time
Filter + Dark Reverb
T7 : CUE rec + Flex, a random retrig pitch +12, lfos on filter, balance, delay time
Filter + Ping Pong Delay

T8 Master : Compressor

What are you using between the OT’s Midi DIN input, and the Launch Control’s USB Midi port?

Andreas_R · 2023-12-30T18:11:50.671Z

Thanks brother! I was looking into ways to use the OT as a FX like emulating different pedals. And an awesome delay was of course on the list too!

Yeap! Needless to say that you can use this with live input as well making it a very powerful delay pedal… You can dub a band playing live even with some sends from the console
