  • Beat+baseline editor is used to make sound loops. This editor uses both instruments plugins and sample sounds to create sound loops. Similar to song editor, just add required plugin or sound sample by dropping to its interface. Compact piano roll is also present with each added sample sound and plugin. Click on the different keys of a piano roll and press play button to listen to the created sound loop.

A full-fledged piano roll and FX-Mixer are two more handy features of this software. Full-fledged piano roll is a virtual piano that you can access by double-clicking on the keys of a compact piano roll. This piano helps you to further fine tune the sound of each key of compact pianos. However, FX-Mixer lets you mix various sound effects with each other to make a new unique sound.
