Arpeggiator/Beats Menu
Master Arpeggiator Parameters
Use the Key Range parameter to set the keyboard range for the arpeggiator. 
Notes inside the range will arpeggiate while notes outside the specified 
range will not arpeggiate. Use the Extensions parameters to exceed the 
upper boundary of the Key Range (see the information about Extensions 
beginning on page 249).
Move the cursor under the first key and use the data entry control to define 
the lowest key to be arpeggiated. Move the cursor under the second key 
value and use the data entry control to define the highest key to be arpeg-
giated.
Arp/Riff MIDI Out This screen allows you to set whether or not arpeggiator and/or riff data is 
transmitted out the MIDI ports for all channels with arps on. The options 
are: don’t transmit, transmit arps, transmit riff, or transmit both.
The arpeggiators are 
contained within the preset 
which is why a “dummy” preset 
must be used.
 
To Transmit Arpeggiator Data to another MIDI Device:
1. Set Arp/Riff MIDI Out (above) to Transmit Arps or Transmit Both.
2. Select an arp: preset.
3. If you don’t want the internal PX-7 preset to sound, create a “dummy” 
preset with no instruments selected and the arpeggiator turned on. 
Name and Save this preset.
4. Connect MIDI Out to MIDI In on your external MIDI synth. (Channels 
1A-16A go out the MIDI A port. Channels 1B-16B go out the MIDI B port.)
5. Go into the MIDI menu and turn “Rechannelize Input” Off. This 
prevents double notes from sounding on the sustained pads.
6. Name and Save the Multisetup if you want to keep the setup.
MIDI Song Start The arpeggiator, beats and the sequencer are all synchronized to the same 
clock (internal or MIDI) Although the arp or beats notes are synced to the 
clock, they may still be out of sync with the downbeat or first note of the 
sequence. This feature allows the arps, beats or both, to “resync” to the first 
beat of the sequence when the sequencer is started. This feature also works 
when receiving MIDI Song Start from an external source.
