I also ran into these problems.
I used AudioEase’s BarbaBatch software to easily convert BWF data, which is apparently WAV data.
16bits / 44.1KHz, Ch: 1, BWF Converts to 24bits / 48KHz, Ch: mono, WAV.
It’s very convenient because you can convert multiple tracks at once, but it’s a bit expensive to buy new software.
Rename the converted data to TRK01.wav.
The data converted in this way can be played back on the SQ Drive multitrack.
for your information.
