Encoder speeds are assignable by the TWEAKER EDITOR’s “encspeedA” and “encspeedB” functions,
by sending a message to an encoder on the Settings Channel, or using the “Set Encoder Speeds”
SysEx Message.
MIDI Feedback
Encoders in Absolute Mode accept standard MIDI Feedback. If the TWEAKER receives a message
with the same mapping as an encoder, it will use the value of that message to set the current value
of the encoder.
For example, If the message “CC57, value 127, on Channel 1” is received by a TWEAKER with default
settings, it will update its stored value for the top-left encoder to 127. If Ring Local Control is enabled,
the LED Ring will update the display the current value of the encoder.
MIDI Feedback Loops
In order to eliminate feedback loops that could lock an encoder at a value, the TWEAKER will
ignore a MIDI message that is mapped to an encoder that is actively being turned by the user. This
is especially helpful for TRAKTOR’s feedback system, which will send a message right back to the
TWEAKER after receiving it in some cases. The TWEAKER can still accept messages that are mapped
to the LED Ring that accompanies that encoder during this period if Ring Local Control for encoders
in Absolute Mode is disabled.
3.2.2 Relative
The TWEAKER’s encoders can also operate in Relative Mode. This version of relative mode is known
as “2’s Compliment.” When in Relative Mode, an encoder outputs continuously in either direction.
Relative Mode is generally used to cycle through long lists, adjust track position, and other
incremental adjustments that require more than the traditional 0-127 output. By default, the large
navigation encoder is in Relative Mode.
The TWEAKER only outputs two messages in Relative Mode:
8 Clockwise: +1 ( velocity/ value 1 )
8 Counter-Clockwise: -1 ( velocity/ value 127 )
One message is output for each click of the encoder (increment or decrement). There are
approximately 30 increments in one full rotation of an encoder. If Ring Local Control in Relative
Mode is enabled, the LED Ring will update to show the direction of the encoder’s last turn.
Ring Local Control in Relative Mode can be controlled using the Local Control feature of the Settings
Channel.
