This program lets you play piano using your computer's keyboard. Although its interface seems simple, the application has a lot of functions. Of course, the main one is the ability of playing piano notes. This is done using the MIDI capabilities of your computer's sound card. You can set the program to play different types of piano, such as, Acoustic Grand Piano, Honky Tonks, Electric, and more. Also, the program can emulate other instruments, such as electric guitar, bass, harpsicord, church organ, and even other non-musical sounds, for example, bird tweets, helicopter noises, applauses, and gunshots. This makes the program very versatile.
It is also possible to control different sound aspects of the instrument. For example, you can modify the chorus depth, tremolo, phaser, and other features, thus creating exactly the sound you look for.
You can also upload SoundFont files, which have pre-recorded music tunes with specific characteristics. For example, a SoundFont file may have a certain amount of flanger, distort, chorus and other effects to produce a very characteristic sound.
As I've said, the interface of the program seems simple, but you can customize it in several ways. It is possible to set your default language by choosing among ten different tongues, such as Spanish, German, French and others. Also, you can show or hide the notes of each key and even "paint" them in different colors.
In general, it is a good program that will help you play and compose music pieces. And the best part is that it's absolutely free.
