Chromaphone 3: Acoustic Object Synthesizer by Applied Acoustics Systems Free Download

The core of Chromaphone 3 is its set of eight physically modelled acoustic resonators. You can combine strings, plates, drumheads, membranes, beams, bars and tubes to imitate familiar instruments or build sounds that do not correspond to any real one.

The developer notes that Chromaphone was the first synthesizer to account for coupling between resonators. The model captures the two-way flow of energy between resonators, which is intended to reproduce the interaction seen in acoustic instruments.

Chromaphone 3 is two-voice multitimbral, so you can layer two timbres or split them across the keyboard. Each layer has four performance macros that can be assigned to modulation, timbre, envelope and effect morphing and played in real time.

The Home view puts the macros in one place for quick tweaking, and the browser can be filtered by Packs, Sounds, Categories and Creators. The multi-effects module includes reverb, equalizer, compressor, tremolo and guitar amplifier processors, and its five slots can be reordered.

For sound design work, the library is a starting point: 420 new factory sounds by a team of named sound designers, plus a remastered set of 676 sounds from Chromaphone 2.
