Qu-Bit Electronix - Octone


Eight step sequencer for melody and rhythm which offers a tempo generator, rests, variable sequence length, a quantizer with six scales to choose from and glide. Octone is also capable of ratcheting behavior with selectable number of gates and gate length per step.
Two modules can be cascaded together to create one duophonic 16-step sequencer.



Per step there is a potentiometer for setting the step CV (0 V to 5 V), a button for activating the gate for the according step and an individual gate output. The sum of all gate signals is available at the GATE OUT.
The RATE potentiometer determines either the speed of the internal clock generator or the gate pulse width at the GATE OUT when the module is synchronized to an external clock.
The RESET socket and the homonymous button are used to reset the sequence. An analog portamento with adjustable time value is available. The module can play in a forward, a pendulum or a random mode. The length of the sequence is determined by the LENGTH potentiometer. (One to eight steps.)

Octone offers three modes of operation:

  • Standard mode STD: The module acts as a regular 8-step sequencer
  • Ratchet: In this mode, gate repetitions per step are played. If two Octones are coupled it is possible to assign and play up to 16 ratchets.
  • Tune: It stops the sequencer and is used for tuning individual step CVs as well as to program number and length of gate repeats for the ratchet mode.

The sequence can be played non-quantized or it can be limited to the following scales via the internal quantizer: Chromatic, Major (ionic), Major Pentatonic, Minor Pentatonic, Minor Harmonic and Whole Tone.
