[PD] [OT] advice about low budget multichannel hardware configs

[Greg Pond]

 I agree with you that 25 is extremely hardware ineffective. I have
created an aggregate device in OS X before but only with two of the
same type of external device but this also seems the best option for a
single cpu.

thanks for the input
