Sorry for the confusion, for all these years, I never noticed the version # lower right! Version 2.1.6 (64-bit).
I tried selecting an audio track when running the timeline. Unfortunately, didn't make a difference.
It chokes with buffer size set at 512. If I increase to 1024 or 2048, the choking stops but can't be played in real-time due to latency issues. (My audio interface is a UA Apollo Twin). I own quite a few EZX's and experience this only with Dream Pop. I'll keep trying different things.
Thanks
