User Manual

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
should you encounter problems with Audio passThru™, try changing these two
parameters until you find a suitable combination."
Port Information
The Port Name here is editable, and the Number of Input/Output channels fields reflect
the settings in the Audio Configuration field above."
Note that you can enable or disable audio to each port, and also that iOS audio is
available only in USB Port 1 (as indicated on the front panel as well). As explained in
the Troubleshooting section near the end of this manual, disabling audio on an iOS
device leaves MIDI active while always enabling the internal speakers, headphones,
and mics."
