Synthogy is a Massachusetts-based audio software company founded by George Taylor and Joe Ierardi, both former engineers at Kurzweil Music Systems. Taylor was a principal architect of Kurzweil's KSP8 multi-effects system and developed Synthogy's audio engine and DSP, while Ierardi is a pianist and sound designer who produced piano modules for Kurzweil. The company specializes exclusively in virtual piano instruments.

Synthogy is best known for its Ivory line of sampled piano software, which has become a widely used standard for virtual acoustic pianos in studio production, film scoring, and live performance. The product range includes Ivory II Grand Pianos, Ivory II Italian Grand, Ivory II Studio Grands, Ivory II Upright Pianos, and the Ivory 3 series — including the Ivory 3 American Concert D, Ivory 3 German D, and Ivory 3 LE Uprights (Modern and Vintage). Ivory 3 introduced the proprietary RGB Engine, which combines deep multi-velocity sampling with harmonic modeling to expand tonal expression beyond what either approach alone provides.

Beyond the desktop plugins, Synthogy has licensed its piano sounds to hardware and mobile platforms, including instruments from Korg. The company's reputation centers on detailed sampling of specific concert and studio pianos — Steinway, Bösendorfer, Yamaha, and Fazioli among the source instruments referenced across the Ivory catalog — paired with engine features aimed at pedal noise, sympathetic string resonance, and per-note tuning behavior.

Synthogy has 4 products cataloged on Equipboard, including Virtual Instrument. Their gear is featured by 17 artists, with the strongest followings in Rock, Electronic, and Pop. Notable users include Mark Isham, Yasunori Mitsuda, and Mike Garson.
