KiraStudio is a lightweight, cross-platform music studio built for clarity, automation, and sound creation. Compose in a fully featured piano roll, build custom instruments by assembling "generators", and connect everything through flexible effect chains. Automation is at the core: shape nearly any parameter over time using ADSR envelopes, LFO-style curves, and step sequences with powerful editors. Create motion, dynamics, and evolving textures with precision. With support for SoundFonts (SF2/SF3), sampling, wavetable and FM synthesis, plus MIDI import/export and WAV/OGG export, KiraStudio scales from quick sketches to full projects. A focused interface keeps you in the creative flow on desktop and mobile. While KiraStudio is currently focused on video game music, its sound engine is built to grow into other genres in the near future.
