- Power up. From the App Menu (long-press right encoder if not there) twist the left encoder to Quadrants, press to enter.
- Double-click A. Twist the right encoder to 'Scale Duet' (or 'Quantizer'), press to load it into the NW slot.
- Double-click B. Twist to 'Turing Machine', press to load into NE.
- Double-click X. Twist to 'Clock Div', press to load into SW.
- Double-click Y. Twist to 'EnvFollow', press to load into SE.
- Patch a master clock into TRIG IN 1; the Turing and Clock Div applets advance on its rising edges.
- Patch CV OUT 1 (NW Quantizer) into a VCO 1V/oct, CV OUT 3 (SW Clock Div) into an envelope trigger, and CV OUT 4 (SE EnvFollow) into a VCA CV.
- Press Z to start the internal clock, or send your own clock to TRIG IN 1.
10HP Teensy 4.1 remake of Ornament and Crime with 8 CV in, 8 CV out and stereo audio I/O. Runs Phazerville Suite — original O_C apps plus Hemispheres applets, with Quadrants hosting four applets at once.

- Long-press the right encoder to reach the App Menu. Twist left encoder to 'Quantermain', press to load.
- Twist the right encoder to highlight channel 1, press, then twist to choose a scale (e.g. 'ionian').
- Repeat for channels 2-4: press to enter, set each to the same scale (or a different one for layered keys).
- Patch four free-running CV sources (random, LFO, sequencer) into CV IN 1-4.
- Take CV OUT 1-4 to the 1V/oct inputs of four VCOs.
- Send a master clock into TRIG IN 1 — Quantermain only emits a new note on a trigger (sample-and-hold style), so each VCO advances cleanly in sync.

- From the App Menu twist to the audio DSP host (the audio slot screen on Quadrants — accessed by entering the audio panel from the Quadrants overview).
- Pick DSP slot 1 and load a Reverb effect; pick slot 2 and load a Delay.
- Patch your stereo source (DAW return, drum machine) into AUDIO IN L and AUDIO IN R.
- Patch AUDIO OUT L/R into your monitor or mixer.
- Patch a slow LFO into CV IN 5; in the Delay slot, assign CV IN 5 to 'time' for moving delay-time modulation.
- Press Z if you want internal clock to lock the delay to BPM.

- App Menu → twist to 'Piqued', press to load.
- Highlight envelope 1: press right encoder, set type to 'AD' and dial attack/decay with the right encoder.
- Repeat for envelopes 2-4 — try AHD with longer decay on env 4 for a slow swell.
- Patch four trigger sources into TRIG IN 1-4 (or remap via the I/O menu).
- Take CV OUT 1-4 to four VCAs / filter CVs / pitch mod inputs.
- Optional: patch a CV into CV IN 1 and assign it to envelope 1 'level' for accented hits.

Behaviors
Quadrants is the Teensy 4.1 front-end for Hemispheres applets, hosting four applets simultaneously (NW/NE/SW/SE) instead of the Hemispheres pair. A/B/X/Y bring each quadrant into focus; double-click for full-screen view, help and to swap which applet is loaded.
Up to 5 DSP slots per audio channel run in parallel with the four CV applets. Optional PSRAM (8 MB or 16 MB) on the Teensy 4.1 enables longer reverbs, delays and granular effects.
Phazerville keeps the classic full-screen apps: Quantermain (4× quantizer), CopierMaschine (4× sample-and-hold), Harrington 1200 (Neo-Riemannian chords), Automatonnetz (Tonnetz + cellular automaton), Meta-Q (meta-quantizer), Quadraturia (quadrature LFOs), Low-rents (Lorenz/Rössler chaos), Piqued (4× envelopes), Sequins (4× step sequencers), Dialectic Ping Pong (byte-beat), Acid Curds (chord progression) and Viznutcracker sweet! (byte-beat sequencer).
Phazerville stores complete applet configurations as Hemisphere Presets, auto-saved on change and selectable via MIDI Program Change or the on-module menu.
Any physical CV input or trigger input can be remapped to any applet input, and any applet output can be sent to any physical CV/trigger output — no fixed channel assignment.
Press the LEFT encoder to start the calibration routine (DAC scaling, ADC offset, display centering, screensaver). Rotate LEFT to enter Reflash mode. Press RIGHT to reset all settings to defaults (with confirm). Long-press RIGHT to return to the App Menu. UP+DOWN dual-press toggles screen flip / I/O reverse.
On the final page of the calibration routine the UP/DOWN buttons select encoder reversal: L only, R only, both (LR), or normal — useful for builders who mounted the encoders upside-down.
Z starts/stops/arms the internal clock; A+B opens Clock Setup (BPM, swing, multiplier, external source). External clock can come from any TRIG input or MIDI clock via the expansion port.
Controls
| Global | Left Encoder | Rotate to scroll the app/applet list, switch pages and make coarse parameter edits. Press to select an entry or enter the calibration routine from the Setup/About screen. rotate = page / coarse · press = select / enter calibration |
| Global | Right Encoder | Moves the on-screen cursor and makes fine edits. Long-press to return to the App Menu from any applet; on Setup/About a press resets calibration to defaults (with confirm). rotate = cursor / fine · press = confirm · long-press = App Menu |
| Quadrants | A button (NW) | Brings the north-west applet into focus in split view. Double-click to open that applet full-screen for help/config or to swap the loaded applet. press = focus NW · double-click = full-screen / change applet |
| Quadrants | B button (NE) | Brings the north-east applet into focus. Double-click for full-screen view and applet swap. press = focus NE · double-click = full-screen / change applet |
| Quadrants | X button (SW) | Brings the south-west applet into focus. Double-click for full-screen view and applet swap. press = focus SW · double-click = full-screen / change applet |
| Quadrants | Y button (SE) | Brings the south-east applet into focus. Double-click for full-screen view and applet swap. press = focus SE · double-click = full-screen / change applet |
| Global | Z button | Start / Stop / Arm the internal clock from anywhere in Quadrants. press = clock transport |
| Quadrants | A+B chord | Opens Clock Setup (BPM, swing, divisions, source). hold A+B together |
| Quadrants | A+Y or X+B chord | Opens the Overview screen showing all four applets at a glance. hold A+Y or X+B together |
