All right, which Baker was supposed to check this? Freezing a synth unmutes all the muted tracks. C'mon guys.. it worked just fine in the previous build :O(

I made a change in this area relatively recently, so if the problem exists it's probably my fault. However I'm unable to reproduce this; I made a couple tracks with some data (including several synth tracks) and froze/unfoze without changing anyone's mute state. If you've got a consistent recipe to reproduce, let us know. 

Tested this using Foxboro (the alpha build that Noel posted up to fix the fast bounce bug), Win7 x86 and all works correctly here on various different projects.
 
Perhaps it's something in the x64 version? Anyone else want to give it a test?

All muted tracks in the project, or just the selected tracks? Can you reproduce this in a brand new project?

I am having trouble reproducing it in a totally new project, though this IS a new project. This one contains plenty of synths, video and tempo changes.
 
It's just very very strange. After freezing all the muted tracks are unmuted.

I am seeing the 2 word phrase "tempo changes" crop up in a number of recent scenarios.
 
Try temporarily removing them and freeze again. DON'T save the project, just close it & re-open to get your tempo  changes back

I believe this is an important question. If not, I think something is corrupt either in the audio file itself or project of some sort.
Best of luck.

I just tested this on a project and not only did it unmute tracks, but it threw a fatal error.
Using Foxboro 64 with Noel's tempo patch.
Sent in a fault report.

Which tracks got unmuted? Could you repro this in a brand new project?

It seems better this morning but still seems to happen mostly when freezing a Computer Music Magazine free synth called Avatar ST... Maybe it needs an update... I shall keep testin'.
