Overview
RatSound is a multi-instrument built from physical modeling instead of samples. That means the sounds are generated by synthesis — bowed strings, reeds, brass, mallets, plucks, and vocal-style models — instead of pulling from a huge library. You get seven instrument families and 31 variants, from grand piano, Rhodes and organ to violin, cello, trumpet, tuba, clarinet, sax, flute, nylon guitar, harp, marimba and four voices, a simple Family → Variant → Parameters layout, and shared controls for ADSR, tuning, velocity, reverb send, and stereo width. Full MPE support gives per-voice pitch bend, pressure, and timbre across 16 voices, so expressive controllers can actually do something interesting.

BrassKnuckles is a sampled horn section instrument — trumpet, trombone, french horn, and tuba — with an ensemble engine, falls and rises, a sub layer, and an FX chain built for horn material.$14.50$29VIEW →Hybrid Bell Instrument · InstrumentRatBells
RatBells plays seven sampled bell families — tubular bells, orchestral bells, crotales, hand chimes, vibraphone, temple gongs and deep tubes — and fuses a modal bell synthesizer and an FM bell into the same voice, with a belfry engine that stacks up to six bells per note.$14.50$29VIEW →Mystical Flute Instrument · InstrumentRatFlute
RatFlute plays the epic-film desert flute: a real recorded ney, duduk and kaval and recorded alto, bass and concert flutes, blended with a modelled ney, kawala, arghul and mizmar, a maqam quantiser with real quarter tones, scoops, maqam ornaments and a vibrato that blooms, over a drone that never breathes in.$14.50$29VIEW →Hybrid Tube Instrument · InstrumentRatTubes
RatTubes is a digital waveguide tube instrument. Tube Length, Girth, Bends, Angle, Material and End Caps shape the resonator; four exciters (Blow, Hit, Whirl and the Rat) drive it; six sampled pipe families (recorder, ocarina, didgeridoo, organ pipe, flute, whistle) sit under it; a Wormhole feeds the tube back through a pitch shifter and three Warp LFOs bend the tube to the beat.$14.50$29VIEW →
