Audio Configuration: this drop-down offers a choice of seven different combinations of
sample rate, number of audio channels, and bit rate. (Audio channels are divided
evenly between the inputs and outputs, and they're all accessible by any computer
device connected to the iConnectMIDI 2+ .)
The higher each of these numbers is, the more data is transferred and therefore more
bandwidth is used. Under some but not all conditions the audio quality may improve
slightly at 24 bits rather than 16, and extremely subtly at 96kHz vs. 44.1 or 48kHz, so
there's a very small trade-off between performance and sound.
In addition, some iOS audio apps support only specific sample rates. If you hear no
audio, set the sample rate to 44.1kHz as the first troubleshooting step.
Number of audio frames to buffer and Sync factor value: as with every device that
processes digital audio, audio goes into a buffer before it is processed (in the
iConnectMIDI 2+ , for routing).
The default settings work well with most hardware and software combinations, but
