One developer working alone in Italy just put out a full groove-production toolkit for house music, for free, with a license that keeps it that way.
Fabio 'Pitch' Serra, who publishes as FaseGroove, released four separate MIDI plugins in beta this week: Piano, Drums, Guitar and Arranger. They cover the exact workflow a house producer needs to build a track from scratch, chords and groove from Piano, swing-heavy rhythm from Drums, strummed accompaniment from Guitar, and a way to pull all three into one arrangement with Arranger. All four run as VST3 on Windows, macOS and Linux, with AU and standalone builds on Mac and standalone on Windows and Linux too.
What does each plugin actually do?
FaseGroove Piano is pitched as a source of "funky piano grooves for soulful, deep and jackin' house, ready to drag into your DAW": it generates alternative chord voicings and phrases while holding onto whatever stylistic direction the producer picked. FaseGroove Drums does the same job for rhythm, with a workflow built around choosing a groove, shaping its feel with swing and humanize controls, then layering in fills and variations before dragging the result into the DAW as a MIDI clip. Crucially, both engines are built to connect genre, rhythm and variation deliberately rather than spitting out random MIDI, so the output stays recognizably house.
Guitar adds strummed and rhythmic patterns to sit under the piano and drum parts, and Arranger is the one meant to tie the whole thing together: pick from 13 genre presets, build a multitrack session using the Piano, Drums and Guitar engines, edit the generated notes by hand, assign sounds per track, and export either a finished mix or separated stems.
Why does the license matter as much as the price?
Free groove-generation plugins exist, but most live inside a subscription or a company's roadmap that can change overnight. FaseGroove is released under the AGPL-3.0, a copyleft license that forces anyone who modifies the code, even to run it as a hosted service, to publish those changes as open source too. That is a deliberate choice for a one-person project with no company behind it: it is a way of making sure the tools cannot quietly get bought, closed off and repackaged as a paid product later. KVR Audio framed the release as something that "democratizes DAW access for producers in underserved regions without commercial software barriers," and that is the real pitch here: no license server, no subscription, no region lock, just four plugins and the right to keep using and modifying them forever.

What's still rough around the edges?
This is beta software from one developer, and it shows. Noizefield's review flagged the lack of a unified interface across the four separate tools as its main complaint, even though Arranger's whole purpose is to bring Piano, Drums and Guitar together into one session. Serra's four GitHub repos, fasegroovepiano, fasegroovedrums, fasegroovearranger and fasegrooveguitar, have picked up 20, 14, 14 and 9 stars respectively since launch: a small but real following for a solo build, and the kind of attention that keeps a project like this alive.
