Audio Loop Player Sync Mode Not Working?

[Mwins]

Hey I'm trying to figure out why the audio loop player is not performing as the documentation states.

It says sync mode will sync the looper to the host's tempo. I have a 4bar loop inserted with the sync mode set to 4bars. Why is the loop not syncing to tempo? Is there something else that needs to be done? Why is there a sync mode if it does not sync... I am confused as to what this actually does.

Can anyone help me out here? Am I missing something?

Are you running HISE as a plugin or are you running your exported plugin?

[Mwins]

@d-healey Thanks for replying. I am running my exported plugin.

[d.healey]

@Mwins Which host?

[Mwins]

@d-healey I'm testing in FL studio because of the popularity. I am going to try in Studio One. However, I have read in other places that time stretching is not possible with Hise... But the documentation for the loop player says that it is...

Edit: Just tried in Studio One and it does not sync either. Have you ever gotten this to work?

[d.healey]

Possible improvements to exported plugins?

@d-healey Ahahaha

@d-healey LOL I see. Testing in Studio One produces the same result. Have you ever gotten the loop player to sync to the DAW?

[d.healey]

@Mwins I've never used the loop player, if you post a snippet I can test it when I have time but it won't be for a few days, or someone else might jump in and test it out.

Has anyone ever tested this?
Does it work?

@MikeB It does "work" for me but I have issues with changing octaves.
I need to leave a gap between any note to get it work correctly.
Got no clue why this is happening but I guess it has time stretching reasons etc.

So if I have a wav in the audio loop player that is 120bpm how do I set it to adjust to the DAW host bpm ?

[d.healey]

Well I'm finally using the loop player in a project and want to know the same as @MusoCity. What do I set the sync mode to for a simple 120BPM loop and does the sync mode actually work?

[d.healey]

Ok I just did some tests. I have found two problems.

1. My loops are 8 bars but the loop player only allows me to select up to 4, so I have to lose the last 4 bars of my loop. I think this should go up to 16 at least.

2. It doesn't auto update with a tempo change. You have to change the sync mode setting after you change the tempo for the loop player to catch on.

@Christoph-Hart I've solved the first issue and added 8, 12, and 16 bar options. I'll make a pull request later.

For the second issue it seems there isn't a TempoListener in the AudioLooper class. I tried adding getMainController()->addTempoListener(this); but I get an instant crash when adding a loop player. Any suggestions?

Here's a scripted workaround:

const alp = Synth.getChildSynth("audioLoopPlayer0");

const th = Engine.createTransportHandler();

th.setOnTempoChange(false, function(x)
{
	var syncMode = alp.getAttribute(alp.SyncMode);
	alp.setAttribute(alp.SyncMode, syncMode);
});
