Microsynth is a polyphonic multi-timbral SoundFont synthesizer designed for microtonal music creation. It supports a wide range of tuning files, allowing users to explore unlimited tunings and assign individual tunings per track. With compatibility for seven types of tuning formats and real-time retuning capabilities, musicians can experiment with any key and pitch combination, offering extensive control over musical expression.

This synthesizer supports up to 16 tracks and integrates seamlessly with standard MIDI hardware controllers and sequencing software such as Sibelius and Finale. It features real-time scale transposition, remapping, and responds to MIDI tuning standard (MTS) Sysex messages. Users can customize MIDI control changes extensively, while the built-in reverb and GM/GS Soundset enhance sound quality. Microsynth also loads and saves scenes for efficient workflow management.

Microsynth functions as a stand-alone application with unlimited MIDI connections and supports audio recording in WAV format. The Mac version offers one virtual MIDI input and output, while Windows users can utilize MIDI-OX for MIDI routing. A mono-timbral version called microsynth-mini is available, sharing the same tuning features. The software includes multiple undo steps and provides responsive support, making it a powerful tool for composers and producers exploring microtonal music.
