Descriptions of Parameters
Setup Editor Parameters
Pressure
All arpeggiated notes play with attack velocities matching the current value of mono pressure
(aftertouch).
Ctrl 117
All arpeggiated notes play with attack velocities matching the current value of MIDI 117, either
from a front-panel controller on the PC2R or received at the MIDI In port.
Fixed Velocity (Fixed Vel)
When the value of Vel Mode is Fixed, sets the attack-velocity level for all arpeggiated notes.
Note Shift
The value of this parameter determines how much transposition, if any, gets applies to latched
notes each time the cycle of latched notes repeats. The transposition is cumulative, and
continues until it reaches the amount specified by the value for the Shift Limit parameter.
Shift Limit
Sets the maximum number of semitones that arpeggiated notes can be transposed up or down.
This parameter is relevant only when Note Shift has a non-zero value. When the transposition
reaches the shift limit, it changes direction according to the value for the Limit Opt parameter.
Limit Option (Limit Opt)
Determines what the arpeggiator does when it has shifted the currently latched notes up (or
down) to the shift limit. There are seven possible values:
Stop
Causes the Arpeggiator to stop the arpeggiation when it reaches the shift limit.
Reset
Causes the Arpeggiator to return to its original pitch and repeat the latched cycle of notes,
transposing each cycle according to the settings for Note Shift and Shift Limit. If the limit allows
the notes to go out of MIDI range (for example, if you set Shift to 12, set the limit to 80, and play
C 4), then those "ghost" notes don't sound, but they take up rhythmic space: the arpeggiator
waits for the cycle to play itself out before starting over.
Unipolar
After transposing to the shift limit, the arpeggiator begins shifting notes in the opposite
direction, until it reaches the original pitch, where it reverses again. To determine the next note
when it reaches the shift limit, the arpeggiator calculates the interval between the shift limit and
what the next note would be if the shift limit weren't there. It then plays the note that is the
calculated interval lower (if reversing from upward transposition) than the last note before the
shift limit. The same thing happens in reverse when the arpeggiated notes get back to the
original pitch. The following table makes this easier to visualize by showing the result of
arpeggiating one note (C 4) in Unipolar mode, with Note Shift set to 3 ST and various values for
Shift Limit.
