Doubling the playback speed of a loop

modulatia · 2015-05-14T09:34:22.000Z

I’ve tried googling but I can’t find information on this.

Essentially I want to take a breakbeat, select it with a parameter lock on the last beat of a phrase, and have it play at twice the normal speed as kind of a fill.

I tried going into the audio editor and changing the tempo/length settings of the sample, but it had no effect on the sound. I tried turning ‘time stretch’ off (in the sample settings AND the flex machine settings) and then raising the pitch, but it was still time stretched. I know I can change this in any wav editor, but that would disrupt the flow of the creative process, so I would prefer to know how to do this inside the OT.

I’m probably just overlooking something, thanks for any info.

Did you try adjusting the ‘RATE’ settings?

Did you try adjusting the ‘RATE’ settings?

Yes. As far as I can tell from the manual and using the setting, it only goes from ‘normal speed forward’ to ‘normal speed backward’. It does not go faster, unless there is some option I am unaware of.

What happens if you play it an octave up when in chromatic mode?

modulatia · 2015-05-14T12:51:32.000Z

Ok, I think I figured this out. Raising the pitch an octave worked once I set timestretch mode to ‘auto’ for the track. That allows samples that are selected with parameter locks to have individual timestretch settings.

Still, if there is a way to do this without raising the pitch, that would be nice to know about. If not, I’m sure I can get the effect I am going for using sliced loops and parameter locks.

In the Arranger you could set up a pattern to play with another tempo (ie doubled, if there is room for it within the BPM range, max 300). But I guess that changes the tempo globally on all tracks in that pattern. Which might be a trouble or not, depending on your situation.

I don´t know how the result will/would be. But you could experiment with having an recorder buffer recording the output (of track or main/cue out), while the Arranger switches from a pattern with low BPM into another pattern with high BPM.

I honestly don´t know if the recorder (and thus also the recording) will be fixed in tempo or if it will just try to follow along the BPM setting from the Arranger. Abovementioned way would be a way to find that out I hope.

Maybe just set half of the original tempo in the sample settings to let the OT speed it up? Not sure if it works, but it should because the OT tries to adjust timestretched loops to the tempo.

EDIT to previous post:

Yes it does!

Just tried out setting three rows in the Arranger with different BPM (120, 60 and 240).
And an recorder that recorded the main output. All changes are there…

Another way to do it is re-render your sample to 22050 Hz sample rate. Then it will play back twice as fast. Turn RATE down to 32 and it will play at the original tempo.

Is this something you do or have done in the OT. If yes, care to elaborate a bit regarding the process?

Go to the attributes page and set the trim length to half its orignal value. The sample will now play at twice the speed without any pitch change (assuming you have your time-stretch settings right).
Set the Rate knob to 32 if you want the sample to play normal speed .
You can P-Lock the rate knob in the playback page too, so you can shift around the speed within a bar a lot easier than going into the arranger and it won’t mess with the rate of your other tracks either.

I actually did mess with this setting, but that was before I learned about the Track’s timestretch setting. Thanks, I will try this out.
