In this application there are three keyboard groups on the screen. You can play many instruments (piano, guitar, violin, xylophone, drum, synth) using the keyboard groups. You can change the octaves of the groups independently so you can play pieces with many octaves.

You can change the attack and release times to have different effects. You can also display or hide the score names on the keys.

Program allows you to highlight the keys belongint to the key signatures. So you can play pieces with different sigantıures easily.

I'd appreciate your feedbacks to improve the program.

Enjoy playing!
