Firo4 Avis

Record up to 90 minutes of live session audio as you play — then output as both a stereo M4A file (clean output and vocal/mic input) and multi-channel MIDI file.

Firo4 is a cutting-edge musical instrument, drum kit, chord builder, and multi-channel looper; all seamlessly designed for maximum playability.

Quickly build complex harmonies with a single touch; push-button chords adjust to include triads, 6, 7, 9, sus2, sus4 and modulation chords while also informing the chorded zither/autoharp.

Output MIDI to control other iOS synthesizers or to desktop synths and workstations via WiFi / Bluetooth.

Share your audio recordings with other iOS apps and save files to your computer when you sync your device.

Choose any key in 7 diatonic modes and 7 secondary scales (Pentatonic, Blues, Whole-tone, etc.) to facilitate stylistic riffs and melodies.

Send realtime audio directly to other iOS apps via Audiobus and Inter-App Audio.

Five auto-expanding, synchronized loopers offer layering, contextual sizing, replay, and simple undo/redo via press-and-hold.

Firo4 is the latest version of Firo (short for Fiddlewax Pro, first released in 2014).

Create new music like never before with an instrument that's built to help you turn your song ideas into reality.

Visual pitch detection allows you to sing what's in your head and see which corresponding notes light up on the keyboard.

Intuitively learn relationships between notes and chords as you play.

Select from four drum modes with both analog and electronic samples.

Tempo control and beat quantization let you easily align looped sequences on the fly.
