D2 Standalone 4 Deck and Mixer Control
Description and Instructions
Since TP3.1 the Performance controls (buttons, faders, encoders) on the D2 and S8 allowed for Override Factor Map option.
This map is for using the D2 to control Decks A/B/C/D as well as mixer functions for A/B/C/D Channel Gain, Volume, 4-Band EQ, and Cue, but NOR Cue Volume, Master Volume, or Filter control like in my D2 2Deck map.
All controls are persistant regardless of Deck - Fader 1 always controls Channel 1 Volume - except for the 4-Band EQ which follows Deck Focus.
the trick was to get the Deck Focus to match the D2 Deck as there is a bug where the Deck Focus doesn't naturally do this.
one problem is the method can get out of sync where the D2 is on A but the Focus is on C. it's not that often and probably because i have been editing the map, but it may occur forcing a restart.
The idea of this map is you can use your computer audio out for sound and control it with the D2 Performance controls.
I actually use my Duet Firewire for Mains and my 2017 MBP headphone port for Monitor out.
