Only One Note heard?

On Play, you only hear the first note played but ARP looks like it’s still playing.

Is your instrument monophonic? Try setting Voice Mode to Mono or reducing the gate value to 1.

Notes keep playing after pressing stop?

This can occur (rarely) when multiple notes of the same pitch are sent to some instruments. Setting an arpeggiator to Mono Voice Mode may help. Pressing Stop 3 times should stop all notes. If all else fails, restart ARP and/or the instrument that’s in a twist.

No sound heard

  • Have you set Velocity to 0 (zero)?

  • Have you set a Binary Pattern for Velocity where all steps are off?

  • Do you have the correct MIDI Channel set for your Synthesizer/VST?

  • Are the outputted MIDI notes within the range of your Synthesizer or VST?

  • Check the Global Settings… Are MIDI Output Options set correctly?

  • Has the cable come out?

Steps Parameter has no effect

If your sequence length does not seem to correspond to the number of steps, check the following:

  • Are you in Classic Mode?

    • In SET Mode, go to Menu >> MIDI Input Arpeggiation Mode and set it to ARP Default

  • Do you have a FX or Modulation targeting Note Offset or Octave?

  • Is Pitch Filter set to a number, try setting it to Off?

Mounting Options

ARP has 100mm VESA mounting points on its underside that enable ARP to be attached to a bracket or stand.

IMPORTANT NOTE: Ensure to use M4 bolts that do not intrude into the case by more than 12mm. Exceeding this depth may damage internal components.
