Hi Saturday,
we have released VST Live 3.0.44 with a fix for a bug that caused long delays when switching songs. Thank you, @Herbert_Schmitt, for pointing out this issue.
You can download it here.
The version history is available here.
See you,
Michael.
I’ve relayed the problem to the devs. 
It also affects glueing MIDI parts.
Could you please specify, what exactly and how you’re trying to achieve this? What kind of MIDI programming is needed? SysEx, CCs, NRPNs?
And: How precisely(!) is you’re Helix connected to your machine?
Hey, I think I may have solved it… kinda? Bear with me…
I think I was creating some sort of MIDI loop in layers that was causing the crash. I have three Global Layers to control transport function:
Helix IN → VM 8 (Transport control) OUT
WIDI IN → VM 8 (Transport Control) OUT
Then I have another global layer
VM 8 IN → VM 8 (global actions and shortcuts for play/pause/loop/next track etc)
It was working before so I could control transport from both helix and WIDI bluetooth controls (midi captain) but I think everything going to the same VM seems to crash it? If I get rid of everything but the Helix → VM 8 it works fine and I can control from the Helix and receive programme/cc changes. I didn’t have the WIDI actually connected this time while it was crashing.
surely that’s a loop?
Virtual Ports are cables. What you send out to VM x OUT goes to VM x IN. So yes, you are creating a loop.
. I have 4 separate events here (click). Every event is aligned on the 1/4 grid.
