About OctanaSynth: MIDI Synthesizer
Transform your Android device into a versatile, low-latency MIDI synthesizer with OctanaSynth.
Designed for musicians, producers, and enthusiasts, this app provides the necessary tools to create, experiment, and perform anywhere.
Powered by the robust FluidSynth audio engine, OctanaSynth ensures compatibility and high-quality performance.
KEY FEATURES:
🎹 SoundFont Support (.sf2 & .sf3): Load your favorite timbres and expand your sound library. Use the included default SoundFont to start playing immediately.
💾 Powerful Preset System: Create and save your own custom sounds. Each preset stores your instrument layers, mixing levels, and effect settings for instant recall during your performance.
🎚️ 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.
🎹 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.
🔊 6-Band Equalizer: Precisely adjust frequencies across 6 bands to shape your sound and ensure it cuts through the mix exactly how you want.
🎛️ Integrated Effects: Add depth and dimension with fully adjustable Reverb and Chorus effects, featuring parameters like Room Size, Damping, Speed, and Depth.
🎨 Streamlined Design: Navigate effortlessly with a newly simplified, modern interface designed for quick access and ease of use in any environment.
🔗 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.
📂 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.
🔌 Flexible Connectivity: Easily connect to MIDI devices via USB for a seamless playing experience.
🎹 Intelligent Multi-Device: Connect multiple keyboards and controllers simultaneously. With automatic connection, new devices can be added during a performance without interrupting the sound.
OTHER FEATURES:
- Global control of Gain, Transpose, and Octave.
- Playback modes per instrument (all notes, highest note, lowest note - allowing it to function, for example, as an organ pedalboard).
- Velocity sensitivity adjustment per instrument.
- Support for Oboe audio driver.
- Option to keep audio active in the background.
