Hohner announces the introduction of a series of revolutionary new apps for the iPad: The Hohner Xtreme II SqueezeBox. Mimicking the layout of Hohner's iconic Corona II Xtreme 34-button diatonic accordion, these intuitive virtual accordion apps feature a super responsive, three-row fingerboard that plays and sounds like the traditional instrument. The Hohner SqueezeBox apps allow musicians to practice chord combinations, scales, and songs on-the-go in five different key combinations and colors. Headphones can be used for private practice, or the audio output of the virtual accordion can be amplified by plugging into computer speakers, or other sound enhancing devices. Players may select to have the note names displayed on the large white pearloid buttons. With the touch of a button, the tonality can be changed from "wet tuning" giving an animated sound, to "dry tuning". This app is ideal for the beginning student or professional musician who needs a simple carry-on companion to compliment his or her actual accordion. While not meant to be a replacement for a real accordion, the app is a convenient and easy tool for practicing, learning, or teaching. GCF is commonly used for Tex-Mex, Conjunto, Norteño, Zydeco, Cajun, Vallenato, and French Canadian.
