So I tested this:

My machine is surface book 2 I7 with 16b 500gb ssd hard drive. Settings are on best performance.

75 measure song. one chorus 6 parts with stately blues style


VST is loaded in ableton 10 live suite with all latest updates. nothing else on any other track.

Song opened that was created in BIAB

render time for 6 tracks of song: just shy of 4 minutes

multi riff for 8 bars starting at bar 12 using track 2687 render time for all 7 riffs: 8 min 22 seconds

Same song rendered in real band: render time : Less than 30 seconds

8 bar multi riff render time: Less than 30 seconds

Tried with brand new progression created in the vst. 32 bars long 80s rock style :

results : Song rendered. Less than 30 seconds.......

8 bar multi riff all riffs: 42 seconds........

Tried to load a different song into vst created in BIAB 78 measures long. Worship style:

render time : 1 min 53 seconds

8 bar multi riff :vst crashed at 2 minutes.

Seems to work fine when progression is created in VST but when loading previously created songs vst has issues.

Can anyone else confirm this behavior?
