  1. 9:21Internal BPM against host sync, plus the half, normal and double multiplier
  2. 10:32The divisions and beats notation read out of the built-in help
  3. 13:30Width, regen and the two limiters, one in the feedback path and one at the output
  4. 15:49Mod adding stereo modulation to the repeats, collapsing with width
  5. 19:19The conversion table for quarter, eighth and sixteenth note delays
  6. 38:42On a live vocal, where the polyrhythm reads as ambience

What it does

A two-line stereo delay whose times are set as divisions over beats rather than note values, so 3 over 2 divides the time of two beats by three. Each line has its own setting, and a multiplier halves or doubles both at once. Tempo comes from an internal BPM or the host. Width, regen, a stereo modulation amount and a low pass filter shape the repeats, with separate dry and wet levels and limiters in the feedback path and at the output.

In the demo

Jade runs it on a Helium-driven piano part, on drums where it builds rhythms out of a plain beat, on acoustic guitar, on a no-input mixer drone and on live vocals. She reads the built-in help and its note-length conversion table on screen.

Worth knowing

The divisions and beats notation takes a moment if you think in dotted eighths, though the help lists equivalents. High regen pushes the limiters audibly, so an extra limiter after it helps.
