Audio I/OAudio input andoutput with MSPMSP 1.x, you would have been required to change all instances of dac~ and/or adc~objects with arguments 1 and 2 to have arguments 8 and 9. With MSP 2, this is no longernecessary.You can simply go to the DSP Status window and choose the eighth and ninth physicalchannels listed in the Input and Output pop-up menus.Logical channels in MSP are only created if there is a dac~ or adc~ object using them. Inother words, if you're only using logical outputs 1 and 2, there aren't 510 unused audiostreams sitting around hogging your CPU. However, since you can mix any number oflogical channels to a single physical channel if necessary, you can create a complex multichannelsetup that will allow other people to hear all of your logical channels when theyuse it on a two-channel output device.44
