This FM synthesizer features four sets of 2-operator FM synthesis engines, allowing up to eight oscillators per note for rich and complex sound creation. It supports up to 64 voices of polyphony and offers extensive multi-channel capabilities with 16 independent channels, enabling the simultaneous playback of 16 distinct sounds within a single instrument. Up to four parts can be layered per note, with velocity and key window control, providing dynamic and expressive sound shaping.

The instrument includes six output busses, comprising two stereo and four mono outputs, assuming the host supports multiple outputs. Users can assign different output busses to each channel or individual sound parts, while polyphony limits can be set independently per channel. The synthesizer offers detailed MIDI controller support with sample-precise responsiveness for volume, expression, pan, pitch bend, sustain pedal, and modulation and feedback levels, ensuring precise control over performance nuances.

Performance optimization is a key feature, with options to disable unused MIDI channels and selectively turn off program change, pitch bend, and controller reception to reduce CPU load. The synthesizer supports all sample rates and maintains true 32-bit floating-point signal processing on a per-sample basis without downscaling. It also maintains compatibility with presets and banks from its predecessor, making it a powerful and efficient tool for sound designers and musicians alike.
