Review swaps

[Brendan Jones]

Once again I've a number of small audio packages up for review that I'm 
willing to swap. They are:


rtirq - realtime IRQ threading 	
https://bugzilla.redhat.com/show_bug.cgi?id=839527

Add64 - an additive synthesizer for JACK
https://bugzilla.redhat.com/show_bug.cgi?id=830664

samplv1 -A polyphonic sampler synthesizer with stereo fx 	
https://bugzilla.redhat.com/show_bug.cgi?id=829971

synthv1 - a 4 oscillator subtractive polyphonic synthesizer
https://bugzilla.redhat.com/show_bug.cgi?id=829970 	


Thanks
