rpm 2012 post-mortem, track 1: periapsis

periĀ·apsis, noun: the apsis nearest the center of attraction : the low point in an orbit

The aim with this track was to make an ambient techno track, along the lines of Aphex Twin’s work on one of my favourite albums, Selected Ambient Works 85-92. I started this on day 8, and worked straight through on it, finishing on day 11. The pad sound on the Blofeld came first, and once I decided on the chord progression to use, I sequenced it in seq24 and added simple drum patterns, using a 909 kit in Hydrogen (but sequenced from seq24 instead of Hydrogen’s pattern editor).

seq24 was a good sketch tool, but I didn’t want to use it for the final track, so I imported the seq24 MIDI file in to Ardour 3, and to my delight it split it in to its separate patterns, adding a new track for each. I added a bass part, using TAL NoiseMaker, and started arranging things; eventually I added a lead part, too, also using TAL NoiseMaker, and added some cutoff automation on each part to add some variety.

Importing patterns from seq24 in to Ardour 3 works surprisingly well

I’d already added TAP TubeWarmth on the bass and lead parts to add some mild distortion, but the overall track still didn’t have quite the lo-fi sound I was after, so I added a TAP TubeWarmth plugin to the master track, too, along with a TAP Vibrato plugin, with quite conservative settings (a rate of about 0.8Hz, and a depth of about 0.7%), to give just a bit of the effect of a warbling tape recording. Another characteristic of tape is its limited high-frequency response; the synths already made good use of their low-pass filters, but the drums benefited from a gentle high EQ cut.

I love the sound of this track; the plugins on the master bus do give it that retro vibe, and while the 909 kit was originally meant as a placeholder, it actually suits that retro vibe quite well. I do think it’s a little bit too repetitive, though — given the time constraints, I stretched it a bit longer and put in less drum variation than I should have.
