Ryan Terrell (aka Eskimo Spy) recently wrote this article to share on AudioCookbook.org regarding MIDI delay and sequencing in Ableton Live, and I agree that it is something that will interest many ACB readers. Ryan writes:

I’ve always wanted a MIDI delay and sequencer built into Ableton. Recently, Max for Live programmers have been coming up with some slick patches to do just that. For those of us who haven’t got the cash for Max yet, there’s an alternative.

While tinkering with the “Note Length” MIDI plugin I stumbled upon an interesting find. The “Note Length” plugin has two modes: Note On and Note Off. Note On simply allows the note to pass through changing only the length of the outgoing note. However, “Note Off” waits for the “Note Off” MIDI message (sent from most synthesizers after the key is released) before triggering a *new* note.

I found that in stacking more than one of these plugins end on end I was able to successfully create a MIDI effect rack built on quantized step increments. Each “Note Length” plugin is waiting for a note to finish before triggering their note. By stacking more than one, and setting the plugins to “Sync” mode, you can delay it by quantized increments.

For added versatility there is a Pitch and Velocity plugin at the end of each parallel rack. The velocity plugin is set to “Fixed” mode, so when the velocity macro for each chain are set at 0, the note doesn’t sound at all, effectively silencing that step.

Finally, there’s are global “Random Velocity” and “Gate” length macros. This will give you global control over all the steps’ lengths, and random deviation by degrees from each step’s programmed velocities.

The implementations of this are two-fold. You can create a type of “MIDI Delay” if you remove any pitch variant, and map a macro (with some tinkering) to the velocity of each step, thereby allowing it to “Decay” over time in velocity. You can also use this as a step sequencer, with 4, 8, 16, 24… etc. steps. The rack I used to make these are built on 16 steps, but it’s entirely modular. Also, with the myriad of “Velocity to ____” (fill in the blank) parameters on every synth in Live, this is a massive breakthrough for my own music. Such is the beauty of racks.
