Tracktion Software

Just played with the new Waveform and it's looking good.

I have one issue though, and that is when a screen update occurs it is often accompanied by a glitch in the audio. This is in a very lightly loaded scenario: one external synth driven through the Insert Plugin device and one VSTi. No other effects. The bigger the screen update, the more likely there is to be a glitch (e.g. resizing the window is pretty much guaranteed to produce a glitch, or the arrangement window scrolling).

I'm running at 44.1k with latency set to 128 on a current iMac with a Behringer 1820 USB audio interface. I've tried doubling the latency but it still occurs (seemingly less often but I wouldn't swear to it). I also have the latency multiplier set to 4x.

I don't get this issue with Studio One 3 or Reaper, so it appears to be Tracktion specific. Any optimisations I could try?

A little further test, with latency set to 256 this time. The glitching still occurs, but it does appear it is only Waveform's own screen updates that cause it - as a test, I opened a instance of Chrome and threw the window around the screen while playing back, and there were no glitches related to the moving/sizing of the Chrome window.

You could try setting the latency multiplier back to 1. I have had funny results when altering that setting, it doesn't always help.

I started out with 1x, I only started playing with it to see if it helped

it may depend on the graphics chip and driver software.
you have a Microsoft OS?

Bung your set-up specs in your signature so we know.

Well, it did say iMac in the original message

Anyway, just popped back to note that after a brief test this appears to be fixed in 9.1.1 so I'm a happy bunny.

I wanted to get back into Tracktion having been around since version 1, on and off (been flirting mostly with Studio One, Reaper, Logic and Cubase in that order), and always liked the workflow and this was really getting in the way.
