Processing and mixing of all tracks was performed in real time on two iPads and others digital and analog devices. Very low latency time allows to use Master FX app together with any other devices (even analog) without audible delays of signal. And with using of external audio interface for iPad (I use Focusrite Scarlett 6i6) the quality of sound processing also is high.
Before and after demo of processing:
iPad used in this track not only for sound processing. One of part was created on a very interesting musical application Virtual ANS.
