5.4.3.5. Using the Main Encoders
In Drum mode, the five main encoders can be used to edit the parameters of the current
Drum track.
Gate
The Gate time parameter is used to adjust the length of notes. Possible values are from 1/
64th of a step (short) to 64 steps (long). These values can be set independently for each step
in a Pattern.
By default, the Gate time is set to half a step length for each event.
Velocity
If a Drum event (trigger) in the current Pattern is too loud or quiet, you can edit its
velocity using this encoder. First select the drum track/sound in question by pressing the
corresponding key of the keyboard, then press the step button for that step in the Pattern.
Turning the encoder will choose a new value in the range 1-127.
The default velocity is 100.

♪ : Drum velocity values are transmitted via MIDI (Out 1, Out 2, USB) but are not sent to the Drum
Gate outputs; they only transmit gates.
Time Shift
The Time Shift encoder can be used to shift the timing of Drum events (triggers) backward
or forward in relation to the beat grid. This can help to add a 'humanised' feel to your drum
patterns. The range is -49 to +50, or half of the current Time Division value.
Randomness
Use the Randomness encoder to randomly mute Drum events in your sequence. Turning this
encoder counterclockwise reduces the probability that an event in a step will cause a trigger
to be generated. In the fully clockwise position, all events will always cause triggers.
