Have been working on this synthesis/processing environment for a private client.

it emulates a dial-up modem from the 1990s, which serialises and transmits audio data but instead of sending data to another modem it sends the data to the local DAC. You feed it audio loops and it spits out modem gurgles. It creates some interesting "ethnic" like loops and uses the Monome grid and arc together with a MIDI cc controller for live performance. You can see the desktop editor and sound quality here:
