    Hi Shoo,

    Page 0 is the only page needed to power up the device and record. Page 2-4 are only required if you want to change the biquad filters, IIR filter, or mixing coefficients. Otherwise those coefficients will be default (no mixing, all biquads are all-pass filters).

    Best regards,
