About Buttr FX
Buttr FX is a Vaughan, Ontario developer that launched in 2025 with a single mission: replace programmed guitar parts with the real thing. Their flagship plugin, buttr, is built from thousands of studio-recorded chord voicings played by session guitarists across all twelve keys. You get major, minor, diminished, and dominant 7 qualities ready to drop into a MIDI track. No modelling, no synthesis. Just sampled performances that sit in a mix the way a live guitarist would. The company was founded by Kevin Ekofo, who produces as Kofo and holds Grammy and Juno nominations, including a 2025 Best R&B Album win for his work on Chris Brown's 11:11 deluxe edition. That production pedigree shows in the workflow: buttr is designed for fast chord progressions, not forensic guitar programming.
buttr Plugin
The buttr plugin ships as VST3, AU, and AAX. It contains over 9,000 recorded chords spanning all keys and the four core qualities. You drag MIDI chords onto your timeline and buttr plays back the matching studio recording. The sound is consistent because every voicing was captured in the same session environment, then mapped to MIDI triggers. Artist expansion packs add more voicings and playing styles; the Utopia pack is one example. The plugin suits producers who need guitar chords that sound tracked, not sequenced, and who want to move faster than hiring a session player for every demo. It works in R&B, pop, and hip-hop sessions where the guitar is a texture layer, not the lead instrument.
