In this video tutorial, we are going to make a rolling, syncopated bass patterns for techno in a fun, fast, semi-random, and spontaneous way. We will deliberately ignore traditional theory in a creative way for useful and fun results; being spontaneous to get started or get unstuck by creating order out of chaos.
1. Set up a very simple bass sound in Operator. Use a single sine wave. Adjust envelope, saturation, EQ, compressor, etc.
2. Play and record about a minute of semi-random notes to MIDI clip, played around bass note range. Literally move your fingers on the keys in a sloppy, fast, non-rhythmic, nearly thoughtless manner. Move up and down occasionally so there is some contrast between notes.
3. Edit MIDI notes – duplicate clip, quantize one clip to 16th notes, and leave the other as recorded. For both clips, turn loop on, set to 1/2 bar duration at first. Play clip with kick/beat and move loop through, adjust start point, and listen for different groove variations that work with the beat. Duplicate and move on, find more. Edit/move notes to change and improve as necessary. Listen with Operator set to monophonic or polyphonic. Try with glide on. Use MIDI note length effect to change durations or vary the feel. Transpose some notes high to create semi-melodic patterns. Maybe do small tweak to Operator sound to suite groove… whatever fits in a couple of minutes.
