Livesynth Pro - is it a no-go?

My old login is dead.  I haven't posted in a while since I've had no tech issues.  The board insisted I make a new account.  Like anyone cares.

Anyway, I just moved all my stuff over to a Q6600.  I was bumping up against the limitations of the old 3ghz P4.
I still use SONAR 7, although 8.5 tempts me with its reported multicore optimizations.  7.x is blazing along on the new PC, except for...

When revisiting old compositions made on the P4 for the last five years, I'm getting distortion, crackling, and miscellaneous weirdness on certain tracks.
Every troublesome track has Livesynth Pro as a source.  I'm assuming this antique plugin has some incompatibility with this particular quad-core CPU.

Is there a workaround that will save me the tedious step of re-assigning every Livesynth Pro track to another soundfont player?  I've already re-purposed the old music PC.

I'm using SONAR 7.x (I forget which update - whatever's most current) on 32-bit XP, SP3, Q6600, 4 gigs RAM, Echo Mia sound card, $15 surplus GeForce OEM something-or-other, no outboard gear.

it's not multi timbral. SFZ+is

And Cakewalk has made it available for free!

I found an even better solution!  It's a free program called CPU CONTROL.  It works flawlessly.  It allows SONAR (or any program) to be switched between multiple cores and 1 core while the program is running - no need for a re-start.  On one core, Livesynth Pro works perfectly, so I don't need to re-assign the huge number of Livesynth Pro tracks in my old compositions to different soundfont players (whew) - and if I want to, I can still use Livesynth, although I'll be migrating away from it in the future to keep the 4-core advantage.  I have tested CPU CONTROL extensively, and on my system it's the perfect fix for this problem.  Maybe other users with similar multi-core issues will benefit from the info:

CPU-Control (Win 98/2000/XP/Vista/7)

Wednesday, 10 January 2007

CPU-Control handles the CPU-affinity for multicore-systems (supports quadcores as well). Instead of running each process on both CPUs you can define it as you want it. For example, if you want to separate the firewall and the anti-virus-software from the graphics-application.

CPU-Controls offers five different ways to control the CPU-affinity:

• Automatic: It chooses alternatingly one CPU for each new process
  

• Manual: You define a list, where you can set the way to handle each process
  

• All processes run on CPU 1, which is useful for old applications which crashes on a dual core system
  

• All processes run on CPU 2
  

• Deactivated
  

My exact method:
Start CPU CONTROL
Star SONAR
In CPU CONTROL, restrict SONAR to CPU 1
Temporarily disable multithreaded processing in SONAR
Livesynth works!

I don't plan on doing this all the time, but when tinkering with old Livesynth music, it's a big time-saver.  I sure used that a lot...
