The Hohner MIDI Melodeon is a Button Accordion / Melodeon CoreMIDI control surface for the iPad.
The app doesn't produce any sound on it own, it is designed for playing hardware and software VST-style MIDI synthesizers via a CoreMIDI compatible interface connected to the dock connector or virtual MIDI instruments like Roland Sound Canvas for iOS, IK Multimedia SampleTank®, or Sonosaurus ThumbJam running on your iPad.
The button layout is based on the iconic Hohner Erica diatonic accordion, and the built-in note guide will help you quickly learn your way around the buttons.
The app has essentially the same button spacing as the real instrument.
Touch the buttons with the fingers on your right hand to play. Buttons light up in green when touched.
This style of accordion plays different notes depending on whether you are pushing or pulling on the bellows.
Touch the anywhere in the bellows image at the top of the screen for PUSH notes, lift your finger for PULL notes.
The PUSH/PULL indicator shows the current bellows direction. Also, the sides of the bellows light up tracking the bellows motion
You may slide your fingers between the buttons.
Touch the MIDI connector icon at the upper left corner to show the MIDI controls.
Using the controls, you may set the overall instrument MIDI volume, MIDI modulation, MIDI channel (1-8), key attack velocity playing style (fixed or variable), velocity min/max, and transposition (+/- 12 semitones).
Both fixed and variable velocity modes are provided to allow for expressive playback. In the variable velocity modes, the X or Y touch position within the bellows sets the velocity for the notes being played. The range for the velocity is set using the Min and Max Velocity sliders.
For fixed velocity, the Max Velocity slider value is used.
You may also set the Max Velocity to less than the Min Velocity to reverse the direction for velocity mapping in the bellows touch areas.
Select between B/C or D/G based layout. Other common tunings can be achieved by setting the transposition control.
For example, for C#/D tuning, select the B/C layout and set a +2 transposition.
Use the "Transmit MIDI Port" switch to choose between "Omni" sending MIDI data to all CoreMIDI apps (matches previous versions of MIDIFlute) or "Virtual Port" sending to a named CoreMIDI virtual output port. When the "Virtual Port option is selected, MIDIFlute will show up as an input option in apps that support virtual ports like Sonosaurus ThumbJam and MidiBridge. "Omni" mode is selected by default.
Touch the '?' icon to show the base layout note names for each button (without transposition).
Touch the '!' icon at the top center to send an "All Notes Off" message to silence any "stuck" notes should they ever occur.
Touch the 'i' icon to show the instructions page.
All settings are saved when the app exits.
Settings for use with other MIDI synthesizer apps:
- In "Preferences", under "Options", enabled "Background Audio".
If using the "Virtual Port" transmit port option, enable the input port under Preferences / MIDI Control / MIDI Input Connections.
IK Multimedia SampleTank:
- In Settings (touch the gear icon), enable "Background Audio".
IK Multimedia iRig MIDI Hardware MIDI Interface:
- For simple direct connection, in MIDI Melodeon, set the "Transmit MIDI Port" option to "Omni" .
- If using a MIDI filtering app like MidiBridge to modify the data stream, in MIDI Melodeon, set the "Transmit MIDI Port" option to "Virtual Port".
Other CoreMIDI compatible synth apps will have similar settings.

New rotated note name graphics that are easier to read from the players point-of-view.
B/C layout now uses the "Black Dot" graphics.
Now re-sends the MIDI volume messages to the treble and bass channels when the app is made active.
Ratings and Reviews

Developer Response ,
Apparently you didn't read the description of the app before buying it, where it says specifically that the app is a MIDI controller and doesn't make sound, and bought this app instead of the Hohner Melodeon Pro app, which is probably the one you actually wanted. Unfortunately, that app requires iOS 10, so it will not run on your iPad. I suggest you request a refund from Apple and next time try reading the description of the apps you purchase before buying them, then posting negative reviews.
Please read the description before buying - it's a MIDI controller for other synth apps
Please read the description before buying - it's a MIDI controller for other synth apps - I keep seeing negative reviews that say "The app makes no sound" or "No hace ningun sonida". That's absolute right. This version of the Melodeon app family is a MIDI controller. It doesn't make any sound on its own. It says so right in the app description. This app is used for controlling other CoreMIDI-compliant MIDI synthesizer apps like ThumbJam and Sample Tank, those apps make the sound, this app is for playing them. It's exactly like using an external MIDI keyboard controller to play a synth program running on the iPad, except in this case, the controller is virtual, running on the iPad itself. The app just sends control signals to whatever synth app you run on the iPad along with this app. If you want an app that makes accordion sounds on its own, you should be buying one of the other Hohner Melodeon apps, not this one. Please take the time to read the description before buying.
I downloaded this, but the sound does not work, I checked setting and theres nothing I can do :(
With Family Sharing set up, up to six family members can use this app.
