Custom Build v1.14 for T32

[djphazer]

(Updated August 30, 2026 - breaks saved preset data from v1.13 and earlier!)

Fresh thread for the PSv1.14 update!

Build Your Own Firmware!

...for Teensy 3.2-based O_C modules! GitHub is kind enough to offer free services that compile everything for you, and you can retrieve the Custom Firmware Artifacts. In fact, you can download someone else's, if it looks good!

New Applet Groups

Don't panic! There are new flags used to select separate groups of Applets from the ever-growing library. No, you cannot fit them all at once anymore. *sad trombone*

By default, you get the Hemispheres host app with 4 preset slots, plus the Scale and Waveform editors. If you don't want Hemispheres, use keyword NOHEMI to exclude it entirely, leaving more EEPROM space for other Apps that need it.

To initiate a request, leave a comment starting with /buildthis followed by a list of the Apps and features you want. Use spaces or commas as delimiters. (Anything that doesn't look like a valid keyword is ignored.)

Below is a list of the valid flags... If you're too greedy, the build will fail!

Try to keep things focused by picking only a few apps or applet categories, and you'll be fine! It's like a 3-module challenge, but with firmware Apps. Good luck!

Bug reports for T32 and Custom Builds go in #254, please.

Bot Syntax

Include the command /buildthis in your comment, followed by:

Feature keywords:

• VOR - for Plum Audio units
• Grids2 - alternate patterns for DrumMap
• NLM or Northern - hardware support for Northern Light Modular units
  • NLM_HOC - for hOC module
  • NLM_2OC_L - for 2OC left side
  • NLM_CARDOC - for the cOC Easel card
• TINRS - special encoder handling for This Is Not Rocket Science O_C modules
• MOAR_PRESETS - 8 Presets in Hemisphere (uses 522 out of 1024 bytes)
  • (consumes half of EEPROM - limits room for other apps!)

Applet keywords:

Choose one:

• PEWPEWPEW - Phazer's Choice selection, plus easter eggs

...or Choose Multiple:

• APPLET_SEQ - all sequencers
• APPLET_QUANT - all quantizers
• APPLET_MOD - modulators, LFOs, etc.
• APPLET_UTIL - logic and utilities (includes MIDI)
• APPLET_WEIRD - audio-rate stuff and some others
• APPLET_CRAZY - unnecessarily large or CPU-hungry stuff

...or choose none, and receive only a Ponglet demo applet. :)

Categories are organized in the hemisphere_config.h file on the T32 branch. You can edit this file yourself, right in the browser and commit your changes to a fork. No need to add or delete anything, just reorder the DeclareApplet lines inside the PEWPEWPEW section. Find your repo Settings and enable GitHub Actions workflows, and future edits will trigger the same robot to do the same work for you, in your own repository (on the Actions tab)!

App keywords:

• NO_HEM or NOHEMI - Exclude Hemisphere and all applets, which frees up about 50% of total Flash storage
• Calibr8or
• Scenery
• MIDI aka Captain
• Pong
• Enigma
  • (will not save TM library if Acid Curds is included, see Acid Curds chord storage vs. Enigma TM storage #75)
• Darkest Timeline
• Neural Net
• CopierMaschine
• Harrington 1200
• Automatonnetz
• Quantermain
• Meta-Q
• Quadraturia
• LORENZ aka Low-rents
• Piqued
• Sequins
• BBGEN aka Dialectic
• BYTE aka Viznutcracker
• Acid Curds
  • (overrides Enigma TM storage)
• Passencore
• References aka REFS

After a minute, check the status here:
Look for the entry with your name on it. If successful, you can download the Artifact containing a .hex file. (Use a browser, not the GitHub mobile app!)

Enjoy, and Please Buy Me a Ko-Fi! ☕⚡

/buildthis with Acid

(this will probably fail)

[djphazer]

/buildthis VOR APPLET_WEIRD

[Ddkin9]

Just curious, with the Applet Keywords, does that mean that full Hemispheres is no longer an option?

Sorry, I just clarified the description. I've split the applets into smaller groups, yes.

[djphazer]

/buildthis PEWPEWPEW APPLET_WEIRD Calibr8or Scenes Piqued

I think this will yield duplicate instances of some applets... but does it fit?

My apologies - Captain MIDI was broken for a silly thing. Just pushed a fix...

Is there a list of applets that show which category each falls into?

[djphazer]

yezzir, the file is called hemisphere_config.h and it's linked in the release notes.

What’s the applet keyword stuff about?

[djphazer]

compromises and tradeoffs. creative limitations.

Nvm I needed to read the release notes. I wish I knew even a small fraction about coding. I basically like your PewPewPew selection but wish there was a couple more weird ones like BitBeat, RungleBook and Lorenz. Any tips on how I’d customize pew pew pew and make it work with the build not thingy? Andrew Nancarrow www.AndrewNancarrow.com<http://www.AndrewNancarrow.com>
