Yes. For a 2-way, 24 kHz for the LF and 48 kHz for the HF. For a 3-way, 12 kHz for the LF, 24 kHz for the MF and 48 kHz for the HF.

Like I said, the added complexity in the XP modules means it’s quite difficult to update FIR Creator EX and FIR Designer to work with them. We might update them in the future but we can’t give any time-frame. Also, the different sample rates on output channels don’t just affect the FIR filters; they also affect the IIR filters. FIR Creator EX and FIR Designer can’t display the summed response of all the channels – only FIR Designer M can do this.
