Powered by the robust FluidSynth audio engine, OctanaSynth ensures compatibility and high-quality performance.


KEY FEATURES:

šŸŽ¹ SoundFont Support (.sf2 & .sf3): Load your favorite timbres and expand your sound library. Use the included default SoundFont to start playing immediately.

šŸŽšļø Multi-Track System & Layering: Organize your instruments into customizable tracks. Layer multiple sounds to create rich textures or control them individually within a single preset.

šŸŽ¹ Note Range & Split Zones: Define specific note ranges for each instrument. Create keyboard splits (e.g., bass in the lower octave, piano in the upper) or intricate layered zones to perfect your performance setup.

⚔ Flux Driver (Pro Feature): Experience the ultimate low-latency performance. The highly optimized Flux Driver ensures an immediate response between your touch and the sound, perfect for
professional live playing.

šŸ”Š 6-Band Equalizer: Precisely adjust frequencies across 6 bands to shape your sound and ensure it cuts through the mix exactly how you want.

šŸŽ›ļø Integrated Effects: Add depth and dimension with fully adjustable Reverb and Chorus effects, featuring parameters like Room Size, Damping, Speed, and Depth.

šŸŽØ Streamlined Design: Navigate effortlessly with a newly simplified, modern interface designed for quick access and ease of use in any environment.

šŸ”— Comprehensive MIDI Mapping: Take full control of the app. Map your keyboard or MIDI controller's knobs and faders to trigger presets, adjust track volumes, control transpose, octaves, gain,
and much more.

šŸ“‚ Session Management: Save and load your complete stage setups into "Sessions." Each session stores your SoundFonts, full list of presets, MIDI mappings, and global settings.

šŸ”Œ Flexible Connectivity: Easily connect to MIDI devices via USB for a seamless playing experience.

šŸŽ¹ Intelligent Multi-Device: Connect multiple keyboards and controllers simultaneously. With automatic connection, new devices can be added during a performance without interrupting the sound.
