About this app

Tradlessons delivers the absolute best sounding Accordion apps for Android!

Hohner announces the introduction of a revolutionary new app for Android:
The Hohner-B/C Double-Ray Black-Dot Button Accordion.

Modeled on the layout of Hohner's iconic B/C Double-Ray Black-Dot diatonic
accordion, this intuitive virtual instrument features a super responsive,
two-row fingerboard that plays and sounds like the traditional instrument.

Reviewers, please read the HARDWARE LIMITATIONS below before posting.

The app is optimized for devices with a screen size of 7" or higher but is still quite playable on smaller screens. Your playing experience may vary on each device, especially concerning multitouch functionality and speed. Please take advantage of the Google Play Store 15-minute trial period to see if the app performs well on your specific device: : http://support.google.com/googleplay/bin/answer.py?hl=en&answer=134336.

The Hohner-B/C Double-Ray Black-Dot app allows musicians to practice scales and
tunes on-the-go. 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.

Touch anywhere above the button board in the bellows or grill to toggle between push and pull of the bellows.

To help with learning the scales, players may show the note names on the large
white pearloid buttons.

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.

B/C is one of the two popular tunings used for Traditional Irish Music.

Download all five key combinations: Hohner-B/C, Hohner-C#/D, Hohner-D/G,
Hohner-G/C, and Hohner-C/F.


Please read before purchase of this app if you have a Samsung Galaxy S2 or S3 phone.

Due to the touchscreen hardware capabilities on some Android phones, specifically, but not limited to the Samsung Galaxy S2 and S3, it is not possible to touch two buttons directly next to each other at the same time along a row or between rows and have them both make sound at the same time.

Because the touchscreen hardware does not send us the touch events for adjacent buttons on the phones, this is not something we can fix in the software.

There is no problem on the phones for playing single note melody lines or chords not on directly adjacent buttons.

This limitation is not present for 7" or larger screen tablets.

I like the app well enough but the description says this is a B/C system and in actuality the note markers are for C#/D. Thats not helpful at all if youre looking to use this as a reference tool. Its quite frustrating. Please fix this.

Another useless app. It's just nothing. A few buttons without (another side) bass. Don't waste your money.

This app is perfect for box players who want to practice in peace or can't take their "real" instrument with them. Hook up a headphone to your tablet and have at it. If you want to know if this app works -- watch TexMex players with their tabelts using Michael's apps. It's great stuff! This is a great addition to a musician's resources.
