Why do my MIDI parts record the start of the looped parts at an offset to where the start of the loop is?
It’s probably something silly that I’m not aware of, but it makes things a little difficult.

eg I have a donut loop set up for 12 bars, I start the recording it gives me a little count down time to prepare, it goes into recording mode and I play the part. When I look at where the part is recorded it has started the loop 4 bars in and looped back on itself so the last 4 bars of the played part are the first 4 bars of the recorded part. I’m not sure why this is happening so consistently.

Some clues from the masters would be appreciated.
Cheers.

Please make a screen recording demonstrating the issue and post a link to it. Also make still screenshots of your playback and recording settings.

OK. Here’s what’s happening.

You’ll see I started the recording on the C, but the recorded loop is starting on the F which is the last note of the sequence.

Is this some kind of sync setting I need to be aware of?

Please post screenshots of your playback settings and recording settings from the global clip settings.

Are the loops all phase-locked?

When loopy records phase-locked loops, it tries to keep the recorded loops lined up or lined up with the clock. So that the loops will play back with the same relation they had when they were recorded. You’ll notice that the orange loop was near the bottom when you started playing back.

I think what is happening is that you are recording a 12-bar loop while the 10-bar orange loop is playing and the master clock is 1-bar. So Loopy is trying to keep the yellow loop aligned with the orange one.

When you started recording the yellow loop, the orange loop looks like it was 6 bars in. So when the yellow loop finished recording, Loopy rotated the loop to try to maintain phase with the orange loop…which doesn’t work out because they aren’t multiples of each other.

If the orange loop had been 12 bars long, you would have seen the yellow loop rotated so the first note would appear where the orange loop was when recording started.

I think with the project you are showing that if the master cycle was 12 and you started playing when the clock was at the top that would have been avoided.

SETTINGS: If you turn phase-lock off and turn phase preservation off that won’t happen. Loop beginnings won’t shift. OR make sure the master clock is set to the length you are going to record and that you start at the top of the cycle.

That may sound complicated, but it is usually what you want. For example, if you had a12 bar chord progression playing in orange, and you started recording yellow four bars into it, you would want the loop shifted at the end so that the first note you played lined up with where orange was at the time.

The videos on this page hopefully illustrate that.

If you are unsure what that all meant after watching the videos , let me know.

@espiegel123 thanks.

It’s the phase lock in the playback settings that creates the offset in the note location.
Turning that off puts the MIDI notes in the expected place.
The phase preservation setting in the recording settings didn’t appear to have any influence on the outcome.

Thanks for your help. 🙂

The phase preservation setting only applies to free loops. Phase-locked loops always use phase preservation.
