Jam Maestro Lite is a powerful music composition tool designed for musicians interested in creating guitar-centric music. With the Lite version, users have the ability to sequence 1x guitar and 1x drums in guitar tab/drum tab format, up to a maximum of 4 bars.

It also allows users to compose songs and includes Midi sequencing and the ability to play background apps using Midi and Inter-App Audio instrument types.

One of the standout features of Jam Maestro is its unique interface, which allows users to easily construct harmonies and visualize the relationship between notes. The app also offers the ability to share tab ideas with friends and bandmates via Dropbox, making collaboration seamless.

In the Full version, users have access to additional features such as 5 instrument types (guitar, bass, drums, Midi, Inter-App Audio), Inter-App Audio Host and Node support, and the ability to connect up to 4x Inter-App Audio Effects.
