Live resampling of a static machine?

How do you do that?

Maybe I don’t understand what you want to do exactly but there’s only one way to slice samples that I know of and that’s to go to the slice tab in the sample editor. Please see the manual for details.

uh yep so I know how to slice things its just I cant slice the recorder buffer without pausing playback so not sure what you are doing there - can you please elaborate on that part?

Pretty sure you can’t slice a record buffer while it’s recording. You can however slice an inactive buffer, and the slices will stay in place if you overwrite it. You’d have to record or assign a sample of the same length as the audio you want to resample to get them in the right place.

Yeah this is what I thought as well. I recorded 16 steps into the buffer then sliced them - but the problem I am having is the buffer is delayed 16 steps because it has to record 16 steps initially before it can play anything back. When I mess with the slice start points on different trigs it will play back a slice from the source which is ahead in time - not the pattern that the buffer is actually playing back. I doubt that makes sense but I’m unsure how else to describe it… lol

I’m going to keep messing around but I dunno if what I’m trying to do is possible.

If it’s a full song why don’t you just slice it ahead of time? I still don’t think I understand what you want to do.

Well, of cause it can’t playback audio from the future. When using a pre-sliced buffer you’ll simply need to be careful that the slices you trigger are already recorded.

And of course you also need to be careful with pitching up which may also run out of already recorded audio data.

But what I don’t get in your case: since the audio is already on the CF card and not really “live”: why not simply jump around the audio with the/a static machine? I don’t see any benefit to treat it like it’s live audio coming in. If you want one track to play through then just use a second static machine with the same sample to jump around and perform whatever you want.

The best way to understand what is possile/not possible with OT and live resample/playback is to watch this video several times: Octatrack Fake-outs: 'Live' Reversing and Re-pitching - YouTube

Trueeeeee, perhaps I am looking at this the wrong way. Thanks for the thoughtful reply man

cool, thanks, I’ll check this out!

Seems like the master has made a video about live remixing… havent watch it yet, but maybe you can draw something from it…

Since we’re already talking live resampling:

How come i can real time sample a track with a recorder and playback on trig one without nudging, but if i pitch down or half the rate, i HAVE to nudge the playback trig?
Shouldn’t it only be when pitching up or reversing? Also, why is it that actually you can’t pitch up if timestretch is on?

Well, I guess that comes from the fact that audio processing is done on blocks of sample values. So if there is any kind of processing necessary before the audio gets sent further up the line such a block needs to be filled first.

You can, with more microtiming delay. It should correspond to this :
Timestretch require 6143 samoles minimum (139 ms).

You can’t playback SRC3 recordings without nudging. You problably hear previous recording, delayed by track length.

Thanks to both. Hard to hear that im sampling the past when just using a sine wave.

You sample the past anyway. :wink:
You can playback “imediately” the current SRC3 recording with microtiming, otherwise you play the previous recording…

Change original sampled track pitch to check if it’s in realtime.

If you sample ABCD inputs with SRC3 off, you don’t need microtiming.

In depth answers to these questions are covered in the video I linked here:

Seriously, @defenestration has put the work in here. It is the definitive reference as far as i’m concerned.

Yes, really good. It misses the use of 2 recorders though, which allows you to pitch up / reverse even more freely. :content:

Yes! Also opens up the door for infinite remixing (as you know!); pattern 1 remixes rec1 MAIN recording while rec2 recording; pattern 2 remixes rec2 while recording rec1. Can slice the buffers when not recording and use prepared patterns. A lot of fun as long as you can keep track!

1 pattern may suffice…

2 recorders can be also alternated, finishing recordings and stop, so that recordings can be mangled freely.

Example :
Recorder 1 records 8 steps from step 1
Track 1 plays rec 1 from step 9
Recorder 2 records 8 steps from step 9
Track 1 plays rec 2 from step 1
(use a sample lock)

Recorders can be alterned more oftenly, so that mangling delay is shortened…
