Operating Systems OS X (Apple) A metronome... Post 302946024 by wisecracker on Friday 5th of June 2015 05:51:03 PM

Hi C688...

I already knew that and have already done similar in some Linux flavours but there is no such animal as /dev/dsp in Apple gear. There is not likely to be either so __direct__ access to a device is not possible. Hence the use of OSX's afplay command that exists in virgin OSX installs.

Bazza...
