Recording starts late with AUs

Post by Misplaced »

Hi, I really like the new AU features added to v6 as you can use a number of apps with their own song modes and timelines to create a self contained groovebox. I have a problem though with the program missing the first beat from the AU in the recording, for example:

Here I have highlighted the first note which is missing from the start of the recording and this throws the recording out by a beat. When I hit play without recording then everything sounds OK, it is just when it is recorded that the start is missed.

The example apps here are DigiStix and DigiKeys.

Thanks.

I tried the DigiStix plugin and with Host Sync enabled, it seemed to work. Although there is a very slight offset I'm going to focus in on. It looks like waht may be happening with yours, is a buffer size issue. What is the audio hardware you are using and what does the Audio Popup (lower left) say when you open the song or plug in the hardware? I'm using a 128 sized buffer at 44.1 kHz (2.8 ms in the Song Options menu)

Thank you for taking a look. I just tried again and this time it worked correctly! I then realised I probably had my bluetooth headphones in when I hit the problem and sure enough once I turned them on then I could recreate the problem again. If it matters, both the internal speakers and bluetooth headphones are running at 48k/256/5.6ms.

Ok excellent, that narrows it down. I'm almost positive there is a latency issue depending on buffer size and it's being compensated for incorrectly. I'll take a closer look and have a fix.

Just tested with the new release and this works fine now. Thanks for the fix!
