What TRIBE does

  • Ten tracks each play any engine: two kicks, the 909 and 808 drum voices, ACID, LEAD, FM4 and NOISE.
  • Every track holds sixty-four clips in four banks, each keeping its pattern, engine, sound, LFO and sequencer settings.
  • Each clip runs 16, 32 or 64 steps with six rates including triplets, four directions and swing.
  • ARP gives the keyboard to the track with arpeggios and transposition, while REC quantises what you play into its steps.
  • Holding keys during playback fires scatter effects: loops, reverse, gate, crush, distortion, ring and filters, on one track or the mix.
  • Two master effects fed by each track's sends offer reverb, delay, drive, crusher, chorus, flanger, phaser, tremolo and comb.
  • SAVE writes changed clips and global settings to the FM-1's flash, and a USB cable with Chrome or Edge installs the firmware.
