Well, my X2 Test project has been running on loop for over an hour now. It contains 22 tracks with the following soft synths (none are frozen):-
Chromophone x2
Z3TA
Rapture
Square I
Dimension Pro (trying out the free strings)
StringsStudio
PSYN II
Loungelizard
SI-Electric Piano
SessionDrummer
Battery
BFD Eco
SI-Drum Kit
True Pianos
SFZ (with Mini Piano)
Tassman
StrumAcoustic
Absynth
UltraAnalog
SI-Bass Guitar
SI-String Section
On each track I have an instance of Console Emulator S-Type, Drive at 3 o'clock and Tolerance on
A couple of tracks have a compressor or EQ ot tube effects, that sort of thing
One track has an instance of TH2 to try that out
One track has Guitar Rig
There are two busses, Master and Reverb.
Master bus has Console Emulation same as tracks and also Concrete Limiter running.
Reverb bus has Console Emulation same as tracks and also Breverb
I've added all of the Console Emulation during this test, so I have been adding it while the project has been playing, expanding and contracting ProChannel strips, generally messing around with setting.
CPU indicator shows first core at around 50% and the other seven at around 30%
Memory commit = 5.6Gb (17%)
Not a crash yet. Only minor gripe is that I'm still having an intermittent issue where R-Mix will show a white-ish screen for some reason.
