Today I decided to record my electric drill. It was on a list of “things i need to record”. Power tools make some great sounds with all sorts of textures and frequencies. I captured the sound of the drill in stereo at a variety of speeds. I also got the sound of switching the drill from forward to reverse. Afterward I chopped it up into a percussive loop and ran it through beat repeat to get a nice mechanical loop going.
Beat repeat has pitch decay setting that incrementally lowers the pitch of repeated slices, which you can hear in the piece. I also maximized the chance settings to increase the likelihood of repeats happening and the variation setting to vary the length of the slices used in the repetition.
Power Tool Percussion
I created this piece today by starting with a few percussive micro samples from a recent field recording and using them as percussion. After programming a simple pattern I ran it through Pluggo’s Harmonic Filter and resampled the results to get two musical loops; one with a low frequency hit that forms the bass in the piece and another with a simple descending melody. 
I programmed a couple of parameters in a VST synth to a controller, set a single note (C1) to play for three minutes and eleven seconds, then recorded the automation. The parameters I was manipulating in real time were the shape of the waveform and the frequency. After recording the automation I added a bit of compression, a nice slow chorus to give it a left to right sweep, and a short delay with a lot of feedback for some added atmosphere. The image is just a snapshot from my photos and has nothing to do with the sound, but you’ve gotta love stick figure warning messages. 
To create this sound I took the bubbles sound from yesterday and programmed it into a simple sampling VST. I built a pattern of chords in a MIDI clip that covered a wide range of frequencies for the sample simultaneously. This created a sort of spectrum of pitches. The next step was to spread that spectrum of pitches by resampling the output in a processor called Fragulator that effectively chops up the sample into fragments that can then be automatically looped at different frequencies. 
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
