Resampling Problem

Hello,

The timing of the Resample seems to be out.

EG track 4 has a a rythmical melody part with some delay fx on it. I resample this to Rec Buffer 2 via REC3. But when Rec buffer 2 is played back, the timing is out.

The resample setup is ONE and QREC is 64. So I press play, then hit REC3 and the OT starts sampling on the next time round the pattern. And then it stops sampling at the end of the pattern. All good, except that the resample timing is off, just a litttle bit, but definitely off enough to completely spoil the loop. Sounds like the whole thing is late.

How do I fix this?

Very best regards to all…

Is the sample start parameter set to zero on the track that plays back the buffer? When you zoom into the waveform in the AED, do you see silence at the start?

Hey Schnork,

Yup that was it, the Sample Start time was set to 03.

Thank you
Have a fabulous day pal.

This got me a few times as well. If sample start is set to something like 2-4, you can’t really see it on those virtual knobs.
But it can also lead to happy accidents, sometimes.

You too have a great day!

Hey, thanks, and Yeah curious…

In that the sample start time set for Trk 2, is “Pre” the Trk 2 Recording Buffer. IE it gets baked in to the audio

I would of presumed, and I think this is more usual, that the Sample Start and End times came post the Recording Buffer. Good to know this! :slight_smile:

Sample start and len do not affect how the sample is recorded. They are post sampling process.

The reason I asked if you could see silence in the beginning of the recording was to rule out other possible reasons.

There was a little bit of silence at the beginning of the recording held within Recording buffer 2. And it dissappeared when I set Sample Start on Trk 2 to 1, it was at 3.

That seems confusing!

If you zoom way in on the beginning of the recording (you can even zoom into the individual samples being recorded in the AED. That’s when you see these little dots appear, so zoom basically goes to max) and sample the same material, sometimes you can see a bit of silence, sometimes more, sometimes less. This is on the less-then-millisecond level, so we won’t ever hear it.

Maybe that’s what you saw?

Anyways, start and len are playback parameters so I’m quite sure they just control the playhead. I better go to my OT and check that… :grin:

Hey Schnork,

I checked, Sample Start time and Sample End time are indeed parameters that are layered on top of the Recording Buffer. As one would expect.

This means that the problem that I had, ie the Recording Buffer being out of time, has another cause, mmmmm

But didn’t you say the problem was gone when you set sample start from 3 to 1?

What else can cause resampling to be out of sync? Apart from having your recorder buffer setup messed up Fin (the fade in parameter) or record quantization when initiating sampling manually, but quantized, there isn’t much.
If rec source and Rlen are set correctly it should capture a perfect loop.

Can you resample again with a recorder trig to make sure sampling starts exactly at the step you want it to start?

On the playback side, make sure pitch and rate are at zero or you’ll get faster/slower playback. And check if your lfo depths are at zero.

Yeah it did seem to fix it. But obviously it wasn’t that, that did fix it. I thought the Sample Start time was maybe adding an offset. But if the Sample Start time iis not recorded into the Recording Buffer then it wouldn’t knock my rhythm off anyways. So…don’t know!

However I have come to understand a number of things from talking to you in this conversation. So all is good! :slight_smile:
