About this app

Pegboard is a mobile synth designed to make playing music more intuitive. The app is a full-featured mobile subtractive synthesizer with a virtual analog filter. Use it as a melody writing app, music scale finder, or just as a MIDI keyboard controller. How you use it is completely up to you.

The keyboard is arranged in a harmonic table layout. Scales you choose are highlighted for easy improvisation. Each chord has a simple shape that is the same in every key. This layout greatly simplifies playing chords, borrowing chords, and modulating between keys.

Music theory apps tend to impose constraints and can be uninspiring. Pegboard will give you an intuitive feel for harmony and allow you to come up with your own amazing riffs all through improvisation. Most of the app features are free. The synth is fully playable and programmable in the free version.

Included in the free version:
• Over 400 unique scales.
• 70 factory presets.
• 16-voice polyphony.
• 4 oscillators.
• 7 effect modules.
• 16-row modulation matrix.
• Unlimited use, no ads.

Included in the pro version:
• Unlimited saved presets.
• MIDI over USB.

The pro version is available as an in-app purchase. It will allow you to use the app as a MIDI controller. You can then connect the app to your DAW or another synthesizer.

Honestly so easy to lay the melody in my head out with this app, because of the scales provided, theres no incident where i cant figure out what note or combination of notes is next in my progression, with Pegboard, its a simple matter, the only critique i have is that the synths are only available in full versions, and although i like sound design, everything i make sounds pretty terrible, no sine waveform in the oscillators, which isn't asking much.. Overall, I give 4/5 Will Smith Slaps

My mind blown from how much is coded in this app! So many tunings and sound customization and presets, but the interface is still somehow very simple, clean and intuitive. I've only been using it for the first time, but I'm super impressed. I'm starting to learn about microtonal music and Arabic music theory so this is so fun to play with and sounds beautiful. I was gonna code my own, but this app is nice for my uses.
