I also own a Phonic Summit (AKA S16) which is unfortunately obsolete
although Phonic still promises at least one more firmware update for it
. It features moving faders and multitrack recording/playback to/from a PC/Mac via USB/FireWire
. The new model is the IS16 which features in addition - remote iPad support, external display and mouse support, and direct to USB drive multitrack recording. Here's the iPad app for it:

Anyways it's interesting to compare the features of those apps to MasterFader and MyFader
.
