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.

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.

Recently I stumbled across an archive of a late night Keston and Westdal jam session buried in a dark, moldy and neglected sub-folder. I looped two bars and put a fade at the end, but otherwise left it untouched. It consists of bass guitar (Nils Westdal), a breakbeat, and myself on Wurlitzer Electric Piano. More specifically a Wurlitzer Electric Piano packaged by Musitronic for use as a student model. I picked this one up in the mid-90’s for a couple hundred dollars. I don’t use it that much since I prefer the sound of the Rhodes, but I think this particular recording is a nice example of the Wurly sound.

One of the things I do frequently, either for the sake of experimentation or for inspiration, is to apply multiple levels of processing with the intent of significantly manipulating an otherwise mundane sound. With a myriad of audio effects available to us this is also a good exercise in learning how certain kinds of processing impacts audio.

I started with a loop of hand drums going through Fragulator (Pluggo). Fragulator fragments the input signal into chunks, similar to grain-table synthesis. The chunks are looped at varying speeds to create a broad variety of effects. It was already drastically different from the original, so I chose to add only one more device. Harmonic Filter (Pluggo again) controls twenty-five filters with a cellular automata algorithm. I used its filter sweep mechanism to spread the stereo spectrum and provide tonal variety over the 1:25 minute recording.

Here’s a snippet from a track I started working on today. I began by using the same techniques I described in Robot Music and in Robot Conspiracy, only I was more deliberate about the patch changes so that they lock in with the tempo a little bit more nicely.

Another technique I used was to cut up individual slices of my recordings and load the samples into Ableton’s virtual drum machine, Impulse, so I could program patterns of the samples into a variety of MIDI clips. I also used a couple of very short sections of AM Radio Static diffused with a healthy amount of reverb.
