Wondering if someone could clarify what limitations exist at 96KHz. I am aware of the list of algorithms that don't work at that sample rate, but are there other limitations of the H9000 at that sample rate?
The optical digital audio IO is not supported at 96kHz (optical SPDIF or ADAT). There is a 96kHz mode for ADAT (S/MUX) that supports 4 channels, but we don't currently implement that. Other than that, the IO capabilites are the same at all sample rates.
There may be slight differences in some of our DSP code for the higher sample rates, but this shouldn't affect the sound of the algorithms. For example, certain modules with long delay lines might reduce the maximum possible delay length for higher sample rates.
