MIDI Arpeggiation in Ableton Live

I recenty had the opportunity to take a good long look at Ableton Live’s Arpeggiator MIDI effect. I have used it here and there in the past, but recently discovered how flexible it is. There are many more algorithms (labeled as styles) than I have seen on other arpeggiators (a total of eighteen styles) for a broad variety of patterns. This example uses the “Thumb UpDown” style. Imagine playing a sequence of notes on your right hand starting with your thumb, then index finger, back to thumb, then middle, etc. and that’s kind of what this particular style does to the notes fed into it. Other capabilities of the arpeggiator include a velocity ramp to manipulate the dynamics of the patterns, and typical parameters like retriggering, gate, and groove.

Cover Your Eyes

A lack of galactic space time has forced me to go backwards for the One Sound Every Day project, but I hope you’ll enjoy this track from Keston and Westdal’s latest release, One Day to Save All Life. Cover Your Eyes started out as a loop of sustained Rhodes notes that I had dropped into Ableton Live during a rehearsal for a show. If I remember correctly, we ended up performing the piece the same night that we created it. I love the samples Nils added that are destroyed with processing creating some complex and swirling textures throughout the piece.

Tracker Stop Effect

I have been busy today working on four or five separate mixes and managed to finalize two of them, maybe. We’ll see how my ears respond after some rest. Anyway, during the last bit of work I was doing I noticed that one of the processor chains was causing insteresting random sounds whenever I pressed stop in Ableton Live. I decided to capture some of these sounds and see if they might be useful in the track.

Live has a great “resample” feature, but it was no use it this case because the only way to create the sound was by pressing stop and when you do that it stops recording. So I opened up Audacity and attempted to route the output from Live into it. After about five minutes I realized this wasn’t working and turned to the web for an answer. I quickly came across Soundflower (Cycling ’74), a “Free Inter-application Audio Routing Utility for Mac OS X”. This allowed me to route the audio to Audacity as I performed starting and stopping in Live. Here’s an edited version of the results. Warning: I normalized the render and it starts out extremely loud.

Forgotten Complex

Now that I have a title for the piece in my last entry, I may as well post a segment from a different layer. This is the main melody. It’s a section of Rhodes Electric Piano that I recorded back in 2005 while testing a live looping technique in Ableton. Today my plan was to find a random clip and run it through some complicated filtering delay and then post the results. Later that same day I completed Forgotten Complex. Currently I have about fourteen different pieces in various states of completion, all as a side effect of my contributions to the One Sound Every Day project.

Percussion Track

This segment of percussion is from a new piece I started on today. To get this sound I used a similar filtering technique that I described in Hummingbird Morse Code on a percussion loop that I had pitched up about two octaves. When pitching up that far on a warped clip in Ableton Live the audio takes on a ratchet like tone. Adding the filtering after that created some low resonant sweeps that add some bass frequencies to the track. I haven’t named the piece yet, so this segment is simply titled Percussion Track, although unlike any percussion I have heard.
