Using Benisphere as a starting point, this branch takes the Hemisphere Suite in new directions, with several new applets and enhancements to existing ones. I wanted to collect all the bleeding-edge features from other clever developers, with the goal of cramming as much functionality and flexibility into the nifty dual-applet design as possible!

I've also included all of the stock O&C firmware apps, but they don't all fit in one .hex. As a courtesy, I provide 3 different build choices with various combinations of Apps in my Releases. I think of it like the boxed set of a movie trilogy or whatever. The O&C Saga. 4 different hardware format options. Free and Open Source, baby!

You can also customize the platformio.ini file to mix & match for yourself ;-)

• 4 Presets in the new Hemisphere Config
• Modal-editing style cursor navigation (and other usability tweaks)
• Expanded internal Clock Setup
• New Apps: Scenes and Calibr8or
• DualTM - two 32-bit shift registers. Assignable I/O.
• EbbAndLfo (via qiemem) - mini implementation of MI Tides, with v/oct tracking
• EuclidX - AnnularFusion got a makeover, now includes padding, configurable CV input modulation - (credit to qiemem and adegani)
• LoFi Tape has been transformed into LoFi Echo - a crazy bitcrushing digital delay line - (credit to armandvedel for the initial idea)
• Sequence5 -> SequenceX (8 steps max) (from logarhythm)

Plus lots of other small tweaks + experimental applets.

Check the Releases section for a .hex file (to be used with the Teensy loader app), or clone the repository and build it yourself! I think the beauty of this module is the fact that it's relatively easy to modify and build the source code to reprogram it. You are free to customize the firmware, similar to how you've no doubt already selected a custom set of physical modules.

This firmware fork is built using Platform IO, a Python-based build toolchain, available as either a standalone CLI or a full-featured IDE, as well as a plugin for VSCode and other existing IDEs.

The project lives within the software/o_c_REV directory. From there, you can Build the desired configuration and Upload via USB to your module:

pio run -e oc_stock2_flipped -t upload

Have a look inside platformio.ini for alternative build environment configurations - VOR, Buchla, flipped screen, etc. To build all the defaults consecutively, simply use pio run

Pro-tip: If you decide to fork the project, and enable GitHub Actions on your own repo, GitHub will build the files for you... ;)

Many minds before me have made this project possible. Attribution is present in the git commit log and within individual files. Shoutouts:

• Logarhythm1 for the incredible TB-3PO sequencer, as well as Stairs.
• herrkami and Ben Rosenbach for their work on BugCrack.
• benirose also gets massive props for DrumMap and the ProbDiv / ProbMelo applets.
• qiemem (Bryan Head) for the Ebb&LFO applet and its tideslite backend, among other things.

And, of course, thank you to Chysn for the clever applet framework from which we've all drawn inspiration.

This is a fork of Benisphere Suite which is a fork of Hemisphere Suite by Jason Justian (aka chysn).

ornaments & crimes is a collaborative project by Patrick Dowling (aka pld), mxmxmx and Tim Churches (aka bennelong.bicyclist) (though mostly by pld and bennelong.bicyclist). it (considerably) extends the original firmware for the o_C / ASR eurorack module, designed by mxmxmx.
