What Vector37 does

  • Four corners each hold two overtone generators, a blend and a filter, and a moon circling a sun decides how much of each you hear.
  • Thirty-two factory sounds cover pads, strings, choir, organ, keys, basses, sequences, brass, leads, wind and drums, each one a whole scene.
  • ALGORITHM picks a planet, and the four knobs across two pages shape its generators, tuning, blend, modulation, cutoff, resonance and level.
  • Hold EDIT and the lowest sixteen keys to select corners, step their modulation and filter types, and mute them.
  • Play the twenty-seven keys, with REC latching notes, SEQ freezing the orbit, GLO focusing and SAVE randomizing the selected planets.
  • Vector37 keeps no store of its own on the FM-1, so another firmware's projects and settings stay as they were.

Its modes

PAGE 1: KNOBS 1-4
KNOB 1 to 4 hold the first four jobs of whatever is in play: a planet's GEN 1, GEN 2, TUNE 2 and BLEND, or the orbit's WARP, WARP Y, ROTATE and CONTRAST.
PAGE 2: KNOBS 5-8
The same four knobs give the second row: MODE, CUTOFF, RESO and LEVEL for a planet, or MOON DIST, SPIN, WIDTH and MOON SPEED for the orbit.
PAGE 3: the PATH
KNOB 1 to 4 set the path's FAMILY, SIZE, SPEED and MORPH.
PAGE 4: the WAVE set
KNOB 1 to 4 set WT POS 1, WT ORBIT 1, WT POS 2 and WT ORBIT 2 for the selected planet's wavetables.
VOICE
ENV opens attack, decay, sustain, release, detune, glide, the voice mode and stereo.
MIXER
FX opens reverb, delay, chorus, drive, reverb size, delay time, feedback and volume.
MORE
LFO opens tune 1, key tracking, filter type, drive colour, chorus depth and speed, reverb colour and audition.
ARP
ARP opens the arpeggiator's mode, BPM, the orbit envelope and the bend range.
