Xen-Arts has released XenFont, a two oscillator, hybrid SF2 SoundFont & Subtractive Synthesis VSTi for Windows. It features full-controller MIDI pitch microtuning using the MTS (MIDI Tuning Standard) format, where any MIDI Note Number can be freely microtuned to any desired pitch across the MIDI range, enabling computer musicians and composers to explore the possibilities of composing music with alternative intonation systems.
XenFont is a microtonal sound-designer's SF2 sample-based synthesizer, with a carefully designed ergonomic workflow for creating powerful sounding and musical useful timbres. The instrument enables users to load their own SF2 SoundFont files and thereby any special timbres required of the music at hand, from classical acoustic instruments, to synthesized ones. Routing the SF2 SoundFont Oscillators through the internal synthesis functions of the VSTi, provides a way to radically transform the original sounds and create new synthesized timbres.
In addition XenFont is designed to be an educational tool for learning about computer music sound-design, sampling and subtractive sound synthesis, as well as musical instrument intonation (aka microtuning and xenharmonics).
XenFont embodies a design philosophy of simplicity for microtonal music sound-design:
- Enables computer musicians and composers to freely load their own SF2 SoundFonts into a fully microtonal, hybrid sampling & subtractive synthesis based VSTi.
- A 'knob-less' design featuring slider controls only, which enables intuitive direct control with a computer mouse.
- A dedicated control signal system mapped to the most important synthesis functions.
- Settings are made by typing values into fields, dropdown lists, left-and-right arrows, switches and sliders.
- Enables musicians to specify precise microtonal pitch-bend settings.
- Features arbitrary microtonal oscillator transposition settings.
- Velocity modulation of harmonics enables dynamically playing harmonics of the fundamental pitch.
- Envelope generators with per-stage ADSR keyboard tracking.
- Two Soundfont Oscillators that enable users to load their own SF2 files.
- Microtonal, Harmonic Series and Subharmonic Series Oscillator Transposition.
