glitching midi over tempo change

[Adam]

Hi there,

I'm getting a bug that's really annoying. I've got a couple of droning (single note) midi sounds, and, I have a tempo change in the session, and, at the moment the tempo changes, the droning midi tracks create a loud popping sound. I'm using the latest version of Cakewalk by Bandlab.  Anybody else having this problem? Is there a way around it? Can Bandlab please address this in the next version?

regards,

Adam

It works on my system (I used a bagpipe for the drone sound). 

And used View/Tempo window to change the tempo.

Did you check the event list for unwanted events?

Did you solo the tracks to confirm the source of the problem?

Hi Robert,

Yes: I've solo'ed the tracks to confirm. The popping is definitely only related to the sound sources triggered by midi (not just one instance; there are three that all pop in the same way the moment the playback hits the tempo change.  There is nothing in the event window excepting the single midi note.

Btw, the midi instrument being used is Kontakt. I'll see if I get the same problem with a different instrument: bear with me.

Okay: I'm more confused than ever. I tried a few different things to replicate the problem.

1. I created a new instrument track (not a Kontakt instrument; an Arturia synth) and played a note over the tempo change and it was clean
2. I copied and pasted the midi track that was in the channel that was popping into the Arturia track and their was a popping sound over the tempo change
3. I tried deleting the midi note in the kontakt channel and reinserting it, and, I'm still getting the popping.

In conclusion, I think the problem is a Cakewalk glitch, but, not easy to replicate consistently.

This came up a few days ago with another Kontakt 6 user. He found that disabling 'External Sync' in Kontakt eliminated the problem.

If any delay is tempo synced you’ll get a pop. I’m guessing that if a patch has any tempo synced effects, same result.
