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: http://chuck.cs.princeton.edu/release/ Thanks and Sorry! Best, Ge!
