Can I connect multiple SQUIDs to my Windows PC/Mac?

If you connect multiple SQUIDs, each USB-B terminal will be recognized as a separate port.
To use with DAW software, properly set the following settings:
- DAW software MIDI settings
- input/output destination
- MIDI channel settings

For details, please see the "Connecting to external equipment" in the Operating Instructions of this unit.
You can download the Operating Instructions from the Pioneer DJ support page
