Pegboard is a free, powerful, and innovative synth app for Android. It has the same powerful sound engine as synths such as the ones in professional music studios.

You can use the keyboard to write music in any key and scale. Every chord is the same in every key. If you play chords, you can easily play with other instruments such as the ones in your band or the ones you use in your daily life.

It is designed to be played using the Android touch screen. If you prefer, you can also use the pro version of the app, which is available as an in-app purchase. It allows you to use the app as a MIDI controller.
