2.3 5-8 button
The 5-8 button activates the knobs from 5 to 8.
2.4 Knobs
The DATA knob act as browsing control when used in specific software or can be used to send a generic
CC number programmable by the user. Refer to the dedicated section on this manual for complete editing
instructions.
This knob can have different behavior (Relative or Absolute):
When working in Absolute (ABS) mode the knob will send values from 0 to 127 on the selected CC (+1
increments per clockwise encoder steps and -1 decrements per counter-clockwise encoder steps).
Once values 0 or 127 are reached they will be continued to be sent if the knob is rotated in the same direction.
The starting value from which to send +1 or -1 values will always be the last one sent by the knob the last time it
was moved.
When working in Relative (REL) mode the knob will send custom values to the selected CC. This will allow the
host application to browse long lists of elements easily.
The Knobs 1 to 8 can be assigned to any Control change number. When the 5-8 function is active the knobs
from 5 to 8 are activated. Refer to the dedicated section on this manual for complete editing instructions.
2.5 Pitch bend - iRig Keys 2 and iRig Keys 2 Pro
Move this wheel up or down to send Pitch Bend messages. The wheel has a central rest position.
Moving the wheel up will increase the pitch; moving it down will decrease the pitch.
Note that the amount of pitch change depends on how the receiving virtual instrument is set.
2.6 Modulation wheel - iRig Keys 2 and iRig Keys 2 Pro
Move this wheel to send Modulation Wheel messages (MIDI CC#01). The lowest position sends a value of 0; the
highest position sends a value of 127.
Most instruments use this message to control the amount of vibrato or tremolo in the sound, but note that this
depends solely on how the receiving instrument itself is programmed and not on the iRig Keys 2 settings.
