For the record the original POST WAS:

A thread for issues you still want fixed or any new issues with X3D. If you've got X3C or earlier versions please go away :)
Straight away I have one.
I have the Melodyne Editor. When installing the X3D patch it prompt for Melodyne installation, asking me whether I want to update/repair or remove melodyne. Wasn't sure what to do so I just cancelled it for now.
 
---------------------

Alex, just click the default setting, and all should be well.

Well the default setting would have removed my VST's - so no :)
Cancel seems to do it...

i'm gonna test the video export a bit later...I shall report back...hopefully an export of a video project wont throw up useless errors with the new engine OR make a video thats usually 200mb into 15gb....
 
Fingers crossed! 

[deleted because Jim Roseberry gave a much better answer]

I'm seeing the crash with more than one VST sending MIDI out listed as being fixed (CWBRN-2504, CWBRN-22141). However I'm not seeing the MIDI crosstalk from VST MIDI out into unrelated tracks while recording listed as being fixed (CWBRN-1336, CWBRN-22142). I thought Noel said it was fixed in X3d.
 
Is anyone with X3d able to verify that the crosstalk has been fixed?

The Melodyne installer launched and found an existing install.
You chose the right option in Cancel (you didn't want to update/remove/change the existing install).   

i'm hoping for a demo version so we can test some of these fixes ourselves

Give 'em a

lawp

Give 'em a couple of weeks... Assuming X3D goes well :)

why a couple of weeks?
