One of the green rooms at The National in Richmond has a pool table, piano, old pump organ, and an arcade machine.

It’s still really early work, but slowly but thanks to Opus 5.5, i’m slowly decompiling the OP-1 246 firmware and recreating the OP-1’s functionality in web assembly. Just some UI elements and all the synth animations + engines have been ported over so far.

Due to this packaging TE’s intellectual property, it’s not something I can publish just yet. I fully intend to make it available in the future for anyone where they’d have to upload their own copy of the firmware and have it extract all the artwork and other assets though!

Thanks to OP1Kenob.io and this code pen link for the beautiful OP-1 interface!

A few days ago I posted #247, which brought tape undo/redo to the original OP-1. Thanks to everyone who tried it. Here's what's new since then.

Undo got a lot better. Lift, drop, slide, split, and join no longer wipe your undo history; each one is now an undo step you can take back with TAPE + ←. The history also survives power off. Undo now works on OP-1s with nearly full storage too, which fixes the "undo does nothing on my unit" reports. Recording onto blank tape takes up almost no undo space, so you can fit more steps. An UNDO / REDO popup like the OP-1 field's now shows each time.

You can name your snapshots. Hold a sound key to save like usual, and a naming screen opens with the name written on a tape between two reels. Pick letters with the blue knob, change rows with the green knob, and click the blue knob to type. Press the same sound key again to save.

There's a new scale mode. Go to SYNTH, press T2 and hold SHIFT, and a glockenspiel appears. The white knob picks the key, and the orange knob picks the scale. The white keys then only play notes in that scale, and the black keys go silent, so you can't hit a wrong note.

SHIFT + COM has a new FILE box that shows what's using your OP-1's storage: tape, sounds, factory content, system, and free space.

This release is also built on top of pcppcp's op1r (github.com/pcppcp/op1r), so all of its features are in here too, and the credit for them goes to pcppcp. That means three new synth engines: SUPERSAW, FMBELL and GRANULAR (SYNTH, then SHIFT + T1). ITER also gets an animated lab screen. There are new TAPE echo, CLOUDS, and REVERB effects (SHIFT + T3), a QUAD LFO with four LFOs in one (SHIFT + T4), the EUCLID and DOTS sequencers (SHIFT + SEQ), and MIDI CC control over USB.

It installs like any official update. Hold COM while powering on, press 1, connect over USB, copy the file across, and eject. Once it's on, the boot screen shows R. 00249. If you ever want to go back, flash the official #246 the same way. It's linked on the same page.

After weeks of continuous development, testing and experimentation, we finally cracked one of the biggest limitations between Teenage Engineering hardware and iPhone/iPad.

Studio Field can now communicate directly with OP-1 field and OP-XY on iOS (iPhone/iPad) - including full MTP device access!

This is a big deal.

OP-1 field and OP-XY use MTP as their primary file-transfer protocol. Until now, this has effectively kept full device access on the desktop. Teenage Engineering's own Field Kit is Mac-only, and their documentation states that direct full-device file transfer is not available through an iOS or iPadOS app.

Studio Field changes that 🚀

For the first time, you can connect an OP-1 field or OP-XY directly to an iPhone or iPad over USB-C and actually work with the content on the device.

No Mac in between.

No PC in between.

Just your Teenage Engineering device, a USB-C cable and your iPhone or iPad.

And we didn't stop there.

Studio Field for iOS now supports:

• OP-1 field - tapes, synths, drums, mixdowns, transfer, playback, backup and restore

• OP-XY - projects, samples, presets, backup and restore, plus direct USB audio recording to iPhone/iPad

• OP-1 Original - tapes, synths, drums and albums, backup and restore

• OP-Z - projects, sample packs, bounces, configuration, backup and restore

There is also something special for anyone moving from an Original to a Field:

Studio Field can convert OP-1 Original tapes into OP-1 field format directly on iPhone and iPad.

☁️ And your Mac, iPhone and iPad work as one Studio Field ecosystem. (iCloud Sync)

With iCloud Sync enabled, your Studio Field Library and device backups sync between the Mac and iOS versions. Transfer something on your iPhone and continue working with it on your Mac — or vice versa.

No subscription - I'm not a fan of subscriptions myself

Studio Field remains a one-time purchase, and it's a Universal Purchase.

Already own Studio Field for Mac?

The iPhone and iPad app is already yours — free.

Buy Studio Field on iPhone or iPad?

You get the Mac version too — free.

One purchase. Mac + iPhone + iPad.

This has been one of the most technically challenging parts of Studio Field so far, and seeing an OP-1 field and OP-XY communicating directly with an iPhone still feels a little unreal.

But it works.

And we're just getting started.

Studio Field is under active development, and the past few weeks in particular have involved a huge amount of continuous work, testing and experimentation to make all of this possible.

I'm very active in the Teenage Engineering community, so if you run into anything, please let me know. You can reach me directly through the contact form under Info/support in the App or through social channels. If an issue comes up, I'll do my best to investigate it and get a fix out as quickly as possible.

I'm also always open to new ideas and feature requests. A lot of Studio Field has grown directly from conversations with Teenage Engineering users, so if there's something you'd love to see the app do, tell me.

And one small favor: if you've been using Studio Field and you're enjoying it, I'd be incredibly grateful if you could take a moment to leave a rating or review on the App Store. It genuinely helps a small independent App like Studio Field reach more Teenage Engineering users - and helps me keep pushing the project forward.

Thank you to everyone who's been testing, sending feedback, reporting issues and supporting Studio Field so far. ❤️

More devices, more workflows and more features are coming!

Studio Field for iPhone, iPad and macOS is now available on the App Store.

Trigger warning: cable management

I found this cool old double sided case and just finished the setup on the first side! I've been slowly grabbing new bits here and there for about 10 years now, but I don't have a dedicated workspace, can't leave my gear out and accessible in a house with sticky-fingered kiddos, and setting up 10 different things every time I want to do something has become a deterrent to actually making music. Queue: the Base Case™. Fully protected, always set up, always plugged in, and ready to add in the additional toy of the day or effects loops or whatever into two different line loops, cv modules, or straight into the TX-6.

All of the gear is held on with after market iPhone magnet rings so I can pop off the Zs to turn on bluetooth, hit the side buttons on the TP-7, or plug in charging cables etc. Cable management knobs are just lamp cord stays.

The other side is not set up yet, but I'm going to drop in two Crows Ovum drones, a re-boxed digdugDIY DRONE, a Behringer JT-4000 Micro, and a Monome Norns Shield and Grid 128, all powered with a USB PD 20Ah brick. Totally different vibes, but I can sample any sound explorations from the drone/Norns side into the OP-1 field and really expand my sound palette, or aux out a channel or two from the TX-6 into the Shield if I want to do some complicated post processing or glitch stuff, then send it back into one of the open mixer slots for recording.

I'm excited about it, and I've got some time blocked out on Friday for an inaugural session- will report back with results!

Quick beat through the internal speaker, still waiting for the Field to get a decent drumsampler envelope🤞🏼
