[chuck-users] turn off midi clock on osx

Hello, I am using ChucK to send MIDI to a MeeBlip micro http://meeblip.com/use-one/assembly-guides-legacy-models/micro-kit-assembly/ through some cheap MIDI-over-USB device which uses a generic driver on OSX. Unfortunately the MeeBlip can't handle incoming MIDI clock/timing data and it seems to be receiving such even though I'm not sending any via ChucK. Is there a way to disable MIDI clock in ChucK, or in OSX, or both? Thank you, michael
