For anyone interested... The way I do the inputing in Digital Performer. I use a Lemur and a MC Transport (control surface transport)
I made a macro in QuickKeys that is triggered by a programed buttons on a Euphonix MC Transport. (it can send Mac key strokes)
Button Push 1) opens the Step sequencing input window for my record-enabled MIDI track and selects and event length of 1/32 note
Button Push 2) I push a button on the Lemur that sends a controller message with x value to trigger articulation, and put the controller # and value in the step sequencer.
Button Push 3) Push button on Euphonix to execute one step, then close the window.
It has been very fast working this way, three buttons to enter an articulation at my cursor. and I love having a 7x12 lighted grid with the names of my 84 articulations on the buttons.
