AUX Sends and USB Audio builds
firmwaregithub.com
AUX Sends and USB Audio builds are experimental firmware builds for the Synthstrom Deluge that add two routing features for outboard gear and computers. AUX Sends turns the Deluge's two CV sockets into an auxiliary send bus: any clip can be sent to the sockets at its own level, independently of the main mix, as two mono sends or one stereo pair, with a master send level, automation, MIDI learn and gold-knob control on synth tracks. It works only on Deluge units with the 7-segment display, because the CV converter shares its connection with the OLED screen, and the CV sockets carry a narrower frequency range than the main outputs. The USB Audio build makes the Deluge a class-compliant USB audio interface alongside USB MIDI, with eight channels out and four in. Each synth, audio or kit track can be sent to its own mono channel or stereo pair and optionally removed from the Deluge's own outputs. Returning audio can be mixed into the song before its effects or used as an audio track's input and recorded like a line input, and a delay-compensation setting holds back the Deluge's own sound so tracks sent through external effects come back in time. While connected as an audio device, the Deluge cannot host a USB MIDI controller.
