SynthDef / Matrix size invalidation

[Sciss]

It seems there might be cache-invalidation problem with synth-defs, when playing around with matrix slicing (expanding and shrinking). It is indicating by errors such as:

Buffer UGen channel mismatch: expected 10, yet buffer has 6 channels
Buffer UGen channel mismatch: expected 10, yet buffer has 6 channels
Buffer UGen channel mismatch: expected 3, yet buffer has 2 channels
Buffer UGen channel mismatch: expected 3, yet buffer has 2 channels
Buffer UGen channel mismatch: expected 30, yet buffer has 12 channels

This was most likely fixed by https://github.com/Sciss/SoundProcesses/issues/26
