Hi Ryan,

--silent mode is mostly designed for offline rendering, so it basically runs as fast as possible. There isn't currently a way to have it run in real-time without also having audio, though that sounds like a nice feature.

Im surprised that you are finding it difficult to get real-time sound working with chuck on RPi. With e.g. Satellite CCRMA [1], its mostly a matter of installing the asound2-dev package and maybe libpulse-dev and compiling chuck as usual.

Hi, I'm running the latest version of chuck on OSX 10.6.9.

I've got a program that doesn't process audio, but it does take MIDI input in realtime and it outputs various kinds of synchronization signals based on it.

I originally tried running it with just the --silent flag but chuck was 'saying' that time durations were way shorter than they were. I attempted the same thing without the --silent flag (defaulting to onboard soundcard) and time durations were accurate. Then, I tried using both the --silent and --srate44100 flags to see if that would help, but it behaved just as it did with the --silent flag.

The ultimate goal is to install this program on a Raspberry Pi without using sound at all (and chuck on RPi freaks out unless you install a bunch of other stuff, if you try to run it without the --silent flag).

Anyway, is there a method or trick to make the combined usage of --silent and --srateXXXXX properly measure duration in realtime use?

Thanks for any help!
