What Golana does

  • Golana plays one analog-style synth with two oscillators, a sub, noise and five filters including MS20, a driven low-pass whose resonance screams.
  • A 16-step sequencer with ties, accents and slides saves with the program, and PLAY starts and stops it.
  • The arpeggiator offers ten types over one to four octaves with latch, swing, gate and steps switched on or off.
  • SCALE LOCK keeps every key in one of sixteen scales, and CHORD plays a whole chord from a single key.
  • Four voices run poly, mono, legato or unison with eight detuned oscillators spread across the stereo field.
  • Four patch routes send the envelopes, LFOs, velocity, keyboard, aftertouch or the mod wheel to pitch, cutoff, amp and more.
  • MOD FX gives chorus, flanger, ensemble, phaser and METAL distortion into delay and reverb, in three orders.
  • SAVE writes any of the 32 programs with its own name, and the clock follows internal, USB or TRS.
