Bug with SysSon Matrix

[Sciss]

sonif-4-compare has a branch that doesn't work:

val vp      = If (cmpIsFirst) Then {
  vr1.play(tp1, interp = 1)
} Else {
  vr2.play(tp2, interp = 1)
}

Giving this error:

Buffer UGen channel mismatch: expected 181, yet buffer has 1 channels

Whereas this works:

val vp      = cmpIsFirst * {
  vr1.play(tp1, interp = 1)
} + !cmpIsFirst * {
  vr2.play(tp2, interp = 1)
}
