Arpeggiator The MPX 1 arpeggiator requires a MIDI note source (keyboard, sequencer, etc.)
to be connected to the MIDI IN connector. Once connected it will arpeggiate keys
that are held down. You can use the arpeggiator as a source to control MPX 1
parameters (like SweepFilter fc , for example), but the real fun starts when you
connect a MIDI sound source to the MPX 1 MIDI OUT connector. The
arpeggiator will “play” the sound source. Parameters are provided to allow you
to turn the arpeggiator on and off, connect a clock source to set the arpeggiation
speed, set the order that the notes are played, and control their loudness.

order
Up-Dn: Notes play in ascending,
then descending order

The V Src parameter allows you to
set the MIDI Velocity value for the
arpeggiated notes. The range of this
parameter is 0–127. When set to 0,
the arpeggiated notes will have the
same velocity values that were
played on the MIDI source. This al-
lows you to control the dynamics of
the notes in the arpeggio by how
quickly you strike the keys.
The arpeggiated notes will all have
the same dynamics when V Src is
set to values between 1 and 127 (1 is
extremely soft, 127 is very loud). Try
patching MIDI Mod wheel to V Src.
Move the Mod Wheel to its minimum
position and the arpeggiator will
track your playing dynamics —
move it beyond minimum and it be-
comes a volume control for the
arppeggios.
