The MPX 1 has a full featured MIDI arpeggiator. It processes held notes received
from MIDI IN and transmits them as arpeggios through MIDI OUT. You can
process the output of the sound generator through the MPX 1, but this is not
necessary to hear the effect of the arpeggiator.
To use the arpeggiator, first make the MIDI connections:
• Connect a keyboard or other source of MIDI notes to the MPX 1 rear panel
MIDI IN.
• Connect the MPX 1 rear panel MIDI OUT to a MIDI sound generator.
• Make sure everything is on the same MIDI channel.
At this point you can load either of two presets that have the arpeggiator
connected (MIDI Arp 1, or MIDI 16th Arp), or you can set up the arpeggiator from
scratch.
To set up a basic arpeggiator:
• Press Edit to display the Edit Select menu and select Arp.
• Set the Arp parameters as follows:
Mode: Up-Dn
V Src: 0
Clock: Puls1
OnSrc: LGate
OnLvl: 64
• Press Edit to return to the Edit Select menu and select LFO 1.
• Set the LFO parameters as follows:
Mode: On
Rate Options: cycles : beat
Rate: 2:1
PW: 50%
Depth: 100%
Play two or more notes at once on the MIDI keyboard and you will hear them
arpeggiated on the sound generator. Press Tap twice to change the
arpeggiation rhythm. Change the Arp Mode parameter to hear different note
orderings. Change LFO1 PW to experiment with staccato and legato phrasing.
