The RSE: realistic audio playback
The RSE (Realistic Sound Engine) technology includes the realistic studio recordings of instruments, as well as some effect modelisations that are the result of years of research.
You'll get access to over a hundred soundbanks, and over fifty effects pedals and amps. We provide many presets for all styles, and you can also configure your own effect chains. You can apply a mastering to the final result, with a compressor-limiter, a reverb, and a 10-track equalizer.
You can also listen to your scores in MIDI sound.
