The Guitoctatrack: Playing the Octatrack with a Line 6 POD HD500X
The Octatrack and the Pod HD500X make a potent combination. The Octatrack can play backing tracks, allow the user to build beats on the fly, and has a powerful integrated looper (the Pickup Machine.) The POD HD500X is a relatively inexpensive amp sim and pedalboard that plays very nicely with the Octatrack and allows for hands-free controls of certain Pickup Machine parameters.
Note: I can’t say whether any of this works for the fancier and much more expensive Helix pedalboards. I blew all my money on the Octatrack.
I’ve seen a couple questions about this combination on a various message boards, but I rarely see any follow ups with answers or details. I’ll add to this post in the future as more things become apparent.

Controlling the Octatrack Pickup Machines via the HD500X
Relevant MIDI information for the POD starts on page B5 of manual.
Relevent MIDI information on the Octatrack and foot controllers starts on page 105 of the manual.
The HD500X (hereafter referred to as the “POD”) can be set up so that each footswitch will send a MIDI message of almost any type: MIDI CC, Program Change - but the one we want is “Note On”. The Octatrack’s (OT) pickup machine “looper” can be controlled by external MIDI messages, allowing us to keep playing guitar while operating the pickup machine with the POD footswitches.
- Set the POD to “pedalboard mode”, this gives us access to all the footswtiches.
- Hold down the “Move” button to get to MIDI assign mode.
- If you have the OT on a specific MIDI channel, change that first.
- Press the footswitch you want to assign.
- Use the rotary knobs to change to “Note On” and use the following for as many of the controls you want. I mapped mine to be the same layout as the POD’s looper.
- Initiate recording: MIDI note 60 = C4 on the POD
- Play / Stop: MIDI note 64 = E4 on the POD
These are the bare minimum you need, the rest can be mapped per the Octatrack manual. Here’s a handy chart for MIDI notes and numbers.
MIDI Clock
The OT can send MIDI clock to the POD, under Project -> MIDI -> Synce, check “Clock Send”.
The POD will pick up that clock which is great for syncing delays. Under the delay time settings, go all the way past the highest value of time settings to get to quarter note, half note, etc. These will follow the tempo sent by the OT.
Cables
The POD has two sets of outputs, balanced XLR outputs and 1/4" unbalanced. The balanced connections are at MIC level and not very good for use with the OT. Use the unbalanced connectors to send audio to the OT, and make sure the toggle switch next to the foot pedal is set to “line level”.
