NEW FEATURE: You can now rotate Eurorack modules by 90° so they fit into a 1U row. This works for modules up to 6 HP wide. Use the Rotate button in the planner action menu. If you don’t see the button, make sure the feature is enabled in your user preferences — or use the keyboard shortcut F for flip.

Turbocharger

FIRMWARE v3.1 Turbocharger got dragged back to the shop. We rebuilt the core around something that should've shipped day one: 1v/oct tracking on the RPM CV Input. Pitch-track your switching speed to your sequencer. Patch CV into RPM CV. The chaos is now tonal. Also pushed faster, cleaner ADC reads on all CV inputs. Free at https://hakailabs.com/turbocharger for owners, and anyone with binary decompilation skills.

Pitchkeeper

What started as an idea to solve a real everyday patching problem became one of our best modules so far. We went through several iterations to get feel, and precision were we wanted it. Pitchkeeper is a precision utility for Eurorack built for accurate pitch CV offsetting, tuning and keeping patches under control. See you at Superbooth 2026 — Booth #Z018, circus tent.
