[chuck-users] update 1.2.0.5b

[Ge Wang]

Hi!

There is now a patched version of 1.2.0.5, which fixes
issues with 'adc' UGen.  Going to multichannel introduced
a bug where adc first output a buffer of random values.
Also the latency is now slightly better.

If you are doing anything with 'adc', you should probably
get the newest 1.2.0.5b:
