What erik37 does

  • You play a sampled concert grand with three velocity layers, key-by-key decay, dampers and their noise.
  • ALGORITHM picks the four voices: CONCERT, STUDIO, VINTAGE and JAZZ, each with its own colour.
  • Twenty notes of polyphony sound at once, with extra room for notes fading out.
  • REC toggles sustain, ENV gives sostenuto and SEL gives una corda, held or latched with a tap.
  • An eight-line reverb offers chamber, hall and church rooms with size, amount and width.
  • PRESETS steps through USER 1 to USER 12, recalling a sound as it lands on each one.
  • SAVE held a second stores the current sound into the preset PRESETS points at, kept through power-off.
  • The keys span F3 to G5 with velocity, and OCT shifts them by octaves while MASTER sets the volume.

Its modes
