Re: [LCtalk] Ableton Live controlling LanBox LCX

[Blair Willis]

Kurt,

Short answer: "Yes"

I have fiddled with a few different approaches to the Note On / Note Off 
issue.  One is the "Ignore Note Off" Controller 65 = 127 that Jon 
mentioned.  I've had issues with this, and it may just be a human 
error... but when I used the Ignore Note Off command it was causing the 
LanBox to behave strangely, switching around certain channels, 
eventually requiring a reset.

Another option: you can use MIDI sustain techniques depending on your 
triggering methods.

My current method is by "looping" clips in Ableton Live.  So I'm 
actually sending a Note On every loop and it remains until the clip is 
deactivated or another clip in the same track (= DMX address, in my 
setup) is launched.  The actual length or duration of the clips varies 
depending on how I'm using it.  I'll tend to use long (64 to 128 
measure) clips so that when multiple clips are running it doesn't 
overload the DMX throughput.  In this manner, I'll use a clip for a 
single function, like setting a DMX address to a specific value, eg 
turning LED's in a fixture to "100% Blue".  That's simple:  just a 
single MIDI note (the Blue LED channel) at held at full velocity for the 
duration of the clip.

However, more intricate clips can be built to create a sequence or 
"chase".  For example the clip can set an LED panel like this:  R-100% 

G-0% B-0%,  R-0% G-100% B-0%, R-0% G-0% B-100%, R-100% G-100% B-100%, 

each for one beat in a 4/4 measure.  This clip (loop) repeats so the 
visual result is: R, G, B, White, repeat....

I'm currently not using any intensity fades, or when I do, it's via a 

physical fader (MIDI velocity programmed).  I do plan on working on the 
type of approach you mentioned, mapping velocity to a CC to use curves.  
Actually, Ableton Live has lots of cool gadgets such as oscillators that 
I could apply to a channel to create some more dynamic effects.
