RHYTHM
In the Rhythm mode, you set counters, or select outputs of the shift
register as sources to generate a binary number that then selects one of
four possible rhythmic states.
Soft key 1 and 2 sources generate a 2-bit binary number to select one of
four rhythmic states. Possible states include note-off (rest), note-on with
50% duration, note-on with 100% duration, sustain, and 32
nd
notes
depending on the Gate Type selected.
Soft key 3 value ranges from 0 – 255. This value determines the possible
density of the rhythm.
With a density value of 0, no matter what state sources 1 and 2 are, a
note-off (rest) will always occur. In contrast, with a value of 255, a
note-on will always occur. As this value is varied, it changes the
likelihood whether notes will play or not, and will include variations of the
four possible states occurring.
