I'm massively interested in the FXCore chip and am trying to actively make some designs. I just wish more people knew about this. It's 24bit/96kHz capable as well.

FXCore can store up to 16 programs and their associated register preset values in its internal FLASH memory so no external program storage is required. By storing preset values in the program header the designer does not need to use instructions just to set initial values.
With 6 potentiometer inputs and 5 switch inputs programs may have real time variable parameters and options such as chorus depth or number of stages in a phasor.
Integrated digital LFOs, ramps and noise generator allows designers to easily program phasors, flangers, chorus and other effects.
