Firo4 is a cutting-edge musical instrument, drum kit, chord builder, and multi-channel looper; all seamlessly designed for maximum playability. Create new music like never before with an instrument that's built to help you turn your song ideas into reality.
• Music first •
Designed from the ground up to help you focus on what you’re creating. Reinvented piano layout extends your expressive potential. Supports 10-finger multitouch and seamless use; keep playing even while adjusting parameters.
• Play your heart out •
Choose from 12 instruments, all optimized for high quality playback. Select from four drum modes with both analog and electronic samples. Add filter and reverb effects to shape your sound.
• Informed by theory •
Choose any key in 7 diatonic modes and 7 secondary scales (Pentatonic, Blues, Whole-tone, etc.) to facilitate stylistic riffs and melodies. Intuitively learn relationships between notes and chords as you play.
• Chords with context •
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.
• Intuitive looping •
Five auto-expanding, synchronized loopers offer layering, contextual sizing, replay, and simple undo/redo via press-and-hold. Tempo control and beat quantization let you easily align looped sequences on the fly.
• See what you sing •
Visual pitch detection allows you to sing what's in your head and see which corresponding notes light up on the keyboard.
• Record your session •
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.
• Share with the world •
Share your audio recordings with other iOS apps and save files to your computer when you sync your device.
• Connect with other apps •
Send realtime audio directly to other iOS apps via Audiobus and Inter-App Audio. Output MIDI to control other iOS synthesizers or to desktop synths and workstations via WiFi / Bluetooth.

Updated Review after Developer Response!
After Developer responded that Firo4 will always be full-featured and never have ads. I had to rewrite my review. I want to thank the developer for making such a cool, free to use (Killer) app!
I’m amazed that such a cool app is totally free, if you haven’t downloaded this app, then take my advice and go ahead, it will be at the top of your favorite “Free” apps, or favorite app period.
There are too many features to list in a review, but some things that surprised me... it has an area to load SF2 files and GET THIS, add your own samples, you can record them right from this app, sample then hit save and use samples right away ... I know sounds way to good to be true!
Killer sounding drums (rock, pop, hip/hop) Piano, Brass, Banjo, Guitar, Strings, Synths, Electric Guitar (saw and square) ect. Quick record /playback feature.
The coolest thing that I find the MOST useful is: the quick chords and keyboard layout (a lot of app charging for just the lay-out) but this thing has quick/useful layout for INSPIRATION without hassle!
Play/Write/Record and everything is on ONE EASY TO USE PAGE!
This app is a GEM! Thanks again Dev. ~Thirdnail

No need to worry - Firo4 will always be full-featured and never have ads. :)
Glad to eee the app back in the store; missed it when it was away. Really useful for getting down ideas.
My wish list:
* save as AIFF
* load samples from Audioshare or Files
* iCloud Drive support between iPhone and iPad versions
* Support for auv3 apps
Thanks for bringing it back!
