Re: SupercolliderAU

I recently built SuperColliderAU and successfully had AudioUnitBuilder
create a plugin, unfortunately it fails Logic's validation for not
retaining a parameter value...

I also tried manually commenting out the Params section of
pluginSpec.plist, this solved the parameter issue, but crashed the
validation tool :) - see below
