OP-1 Field: how do you disable local keyboard while keeping MIDI out? (Local Off equivalent)

Hi everyone,

I'm using my OP-1 Field as part of a custom MIDI chord setup and I can't figure out how to disable the local keyboard sound while still sending MIDI out.

What I'm building: I have a Monome Norns running a custom Lua script that emulates a chord. The signal flow is:

  1. I press a key on the OP-1 Field
  2. The OP-1 sends the note via USB-MIDI to the Norns
  3. The Norns builds a full chord (e.g., I press C → it generates C major, or Cm7, or whatever extensions I've selected)
  4. The Norns sends the chord back via MIDI to the OP-1
  5. The OP-1 plays the chord through its own synth engine

The problem: the OP-1 plays both the originally pressed note (from local keyboard) AND the chord notes from MIDI in. I only want to hear the chord. I need the OP-1's synth engine to play (so I can't just unplug), but I want the local keyboard NOT to trigger sound, only the MIDI input should.

On most synths this is called Local Off. I've dug through the menus and the only MIDI-related thing I can find is the CTRL submenu, but I can't tweak my synth when I'm in this control mode.

What I've tried from the Norns side:

  • Sending a note_off back to the OP-1 right after receiving the note_on → kills the local sound, but also kills the OP-1's key tracking, so when I release the key no note_off is sent and the chord rings forever
  • Sending CC 120 (All Sound Off) right after the note_on → no audible effect at all, which suggests the OP-1's local audio engine isn't reachable via MIDI CCs (separate voice pool from MIDI-in)

So I'm convinced this has to be done on the OP-1 side. Does anyone know:

  1. Is there a hidden Local Off setting on the OP-1 Field? Maybe in a sub-menu I'm missing?
  2. If not, is there a SysEx command or some other trick that achieves the same thing?
  3. Has anyone built a similar setup and worked around this?

Any pointers would be hugely appreciated. Happy to share the Norns script when it's done it's a fun way to use the OP-1 as an Orchid-style chord instrument.

Thanks!

Which Swatch x Audemars Piguet Royal Pop is your favorite?

Now that the Swatch x AP “Royal Pop” collection has officially been revealed, I’m curious which model people here actually prefer.

Not talking resale value or hype, just pure design/vibes.

Best place to buy a used Playdate in Europe?

Hey everyone,

I’m kinda struggling to find a Playdate in Europe, especially in France. I’ve been checking Vinted and Leboncoin (basically France’s Craigslist) for weeks and there’s almost nothing available.

I’d really like to avoid paying ~80€ extra for shipping + taxes by ordering directly, so I’m mainly looking for a second hand one.

Does anyone know good places to look in Europe? Maybe some local marketplaces, Discord servers, forums, or communities where people resell them?

Thanks a lot 🙏

I absolutely loved Persona 5 Royal and got really attached to the characters and overall story. Now I’m considering playing Persona 5 Strikers, but I’m a bit on the fence.

Is it actually worth it from a story and lore perspective? Does it meaningfully continue the Phantom Thieves’ journey and develop the characters, or is it mostly focused on gameplay with a lighter narrative?

I’ve heard that Kasumi isn’t in it, which is already a bit disappointing since I really liked her in Royal.

Also, I’ve looked a bit at Persona 5 Tactica but honestly the art style kind of puts me off, it feels a bit too cartoonish compared to the tone I loved in P5R.

Curious to hear your thoughts, especially if you went into Strikers right after Royal.
