Phybes is a free software synthesizer developed by xoxos. Available format(s): VST for Windows.
Phybes is a physically modeled VST instrument suited for emulation of vibraphone and similar mallet instruments. A mass-spring modeled mallet impulse is applied to a banded waveguide to produce continuous tonal variation in response to dynamic performance. A coupled waveguide creates resonator and modulation effects to provide a low resource emulation with pleasing dynamic timbrality suitable for many compositional applications.
