Keyboard Instrument Simulator is a free app available for iPhone and iPad that transforms your device into a professional keyboard musical instrument. With a wide range of high-quality instrument sounds like piano, accordion, trumpet, and saxophone, this app offers an immersive musical experience.

One of the standout features of Keyboard Instrument Simulator is the variety of style loops available, catering to different genres of music from rock to Arabic, Turkish, Persian, and Kurdish. With three octaves and the ability to transpose the keys, users have complete control over their musical compositions. The app also includes a pitch bend feature, emulating the experience of playing a real keyboard.

In addition to the extensive sound library, Keyboard Instrument Simulator offers major and minor chords, pad sounds, and STS buttons for quick instrument and chord changes while playing. The app also provides a quarter flat tune setting for oriental or Middle Eastern music enthusiasts.

With an audio mixer to adjust the levels of style, instrument, chords, and pads, users can customize their sound to perfection. The app even includes a high-quality stereo sound recorder, capturing the essence of real instruments in a studio environment.

It's important to note that the app requires a subscription to access all features. There are two subscription plans available: a monthly plan and a yearly plan. The monthly plan provides access to all app features for one month, while the yearly plan offers a discounted price for a 12-month access period. Subscriptions automatically renew unless cancelled at least 24 hours before the next period's start date. Users can manage their subscriptions and cancel anytime through their iTunes Account Settings.
