OctaTrack loop issues

Pcunningham · 2024-04-15T11:33:58.880Z

Hey guys

Using an octatrack in a live band set up to trigger simple audio loops. Our synth player has an analog 4 which is the “brain” of the show and i’m linked to that via midi.

All tunes are working fine & in sync except one. Unlike the others - the audio sample is actually a 9 bar loop (all the others are 4, 8 or 16 bar loops.

After doing some digging i’ve got it set as a one shot (yellow trigger) with loop on and tstr off. It seems to be totally hit or miss whether the sample plays in sync with the analog 4 when he presses play on that new song/new bpm. Sometimes it has a little rolling stutter at the start of the loop, sometimes it’s slightly out of time, sometimes it’s perfect, sometimes it doesn’t play at all?

Any help more than welcome.

A simple solution may be that if I stop everything my end and just press play when i want to. However i can’t seem to get it to sync to the analog 4 at the next available beat 1, instead it just plays when ever i hit play.

Thanks guys

Pete

Hi Pete,
it seems that you not use the “Pattern per Track” and “Use Proj. Set” in the Scale mode (Function + PTN).

Also you can select per Audio-Pattern 1 - 8 “play free”

Welcome @Pcunningham

Pcunningham:

when he presses play on that new song/new bpm. Sometimes it has a little rolling stutter at the start of the loop, sometimes it’s slightly out of time, sometimes it’s perfect, sometimes it doesn’t play at all?

So the loop starts just at the beginning, just after START sent by A4 ? And there are timing issues due to clock adaptation at the beginning ?

OT as master clock is better for a free looping purpose.

STATIC or FLEX ? (I’d use Flex)

What about a dummy silent pattern before triggering the sample ?

It can also be triggered quantized once the clock is stable.

Pcunningham:

one shot

I’d use 1ST trig condition. (TRC).

Dayflight:

Pattern per Track

Do you mean Scale per Track ?
9 bars is 144 steps, so a 36 steps track with 1/4 multiplier should do the trick…

Hi Pete,
in the Octatrack MK1 or 2 you can individual each track in its behavior, if it plays only 1 trig or 18 or 53.
By Function + PTN you reach the scale mode. There you can select how each Audio or Midi Track schoud work.
