Spacey arpeggios and echoes

The sound of science-fiction scores and 1970s space rock: arpeggiated chords bouncing through tempo-synced delays, huge detuned pads, gliding leads and sequencer runs through a sweeping filter.

  1. An arpeggiator

    In Modular mode, patch Keyboard → Arpeggiator → Oscillator (Note) and Envelope (Gate). Hold a chord: the arpeggiator plays its notes one by one at Rate. Try up-down over 2 octaves at 1/16, and switch on Latch so it keeps going after you let go.

  2. Echoes in time

    Add a Ping-pong delay after the amplifier with Sync at 1/8d (a dotted eighth). Each echo lands between the arpeggio's notes, so the pattern seems to multiply into a cascade. Feedback around 0.5 keeps it going without running away.

  3. A huge pad

    Set an oscillator's Unison to 7 and Spread to 25 cents: seven slightly detuned saws spread across the stereo field. Give the envelope a slow attack and a long release, let an LFO at 0.07 Hz move the filter, and end with a Shimmer.

  4. A gliding lead

    For a singing lead, use Voices 1 and turn up the oscillator's Glide to about 0.1 s: overlapping notes slide into each other. An LFO at 5.5 Hz into Pitch (Pitch amt 30–50 cents) adds vibrato; a Tape delay with some Wow makes it drift.

  5. The running sequence

    A Step sequencer into a saw with a resonant filter, whose cutoff a slow LFO (or an automation lane) sweeps up and down. Add a Flanger and an Auto-pan for the swirling, rushing quality.

  6. Put it together

    The demo "Starship bridge" layers all of this: pad, arpeggios, a sub drone, timpani-like toms and a slow melody, with a shimmer and an echo bus. "Running sequence" and "Kosmische" show the sequencer side.
