DSP Optimization for this Modular Mixer v2 module

Channel S4 has been optimized and verified (Rec Channels etc). 

You can follow and download beta version of optimized Mod Mixer v2 modules on this thread.

The optimization concern internal circuitry and allows to save 1 Xite-1 DSP (almost 6000 cycles) when building a modular mixer.
