Grantophone a Windows Phone app for the musically inclined


Grantophone is one of those Windows Phone apps that may not appeal to everyone but could prove interesting for those who are musically inclined. It is a feature rich musical instrument that is full of expression and creative potential.

Grantophone has been updated several times since we last looked at the music app and after receiving several tips to revisit the app, we are shining the spotlight on it once again.


When you first launch Grantophone, you will be greeted with a page that offers some direction for the app as well as the developer’s contact information.  Just tap “Play the Grantophone” to get things started.


The keyboard stretches the entire screen with a four-octave range that stretches up the keyboard.  An edit button rests in the upper right corner of the keyboard to adjust everything from waveform to slide rates.  Tilting your Windows Phone will control the vibrato.  Tilt your Windows Phone towards you to increase the range of the vibrato, tilt the phone to the left to increase the speed and to the right to decrease the speed of the vibrato. There are twelve slots to store presets with the ability to have multiple presets active at the same time.


Personally, I don’t have a musical bone in my body and in my hands, Grantophone is nothing more than a noise maker.  I will defer to the developer’s demo video below to demonstrate Grantophone’s capabilities as a musical instrument.

Grantophone has been around the Windows Phone Store for years and remains one of the more creative musical instrument apps available.  It is a free app available for both Windows Phone 7.x and 8 devices.  You can pick up your copy of Grantophone here in the Windows Phone Store.

Cool app. Now I sorta have a synthesizer in my pockets...

Really awesome, but I hope very much by the arrival of a DAW app, I recently found the Zquence Studio 2 in beta, also it would be nice to see the FL Studio mobile on Windpws Phone Store.

I don't care what you think!

Echo, echo, echo, echo.......

I played with it a few minutes and all I can say is (excuse my French here): Holy Sh**t!!!!

This app does pretty much what my 800$ Synth does and it does it well. I can't believe that I would ever say that, but I just fell in love with an app.... Once I have my 1520 and can take advantage of the larger screen (larger keys) I will hook that baby up in my studio...

This app put a big smile on my face lol. I am with you on the 1520, I can't to see how it looks and sounds.

Wow I didnt know that my Lumia 720 supporter multi point touch

Nice app indeed

dalydose says:

This is pretty cool. I'll have to see if I can do anything with it.

My favorite thing is the comments on YouTube are currently all Android users asking for their version.

musarator says:

drained my battery so many times on my 920 with this app..

I downloaded this app long ago, it was amazing, then it got a bit complicated for a musical noob like myself, but it's still definitely very cool.

kotsoft says:

I would encourage you to give it another try. I myself agree that v1.9 was a little poorly laid out and the lack of presets was a bummer. The new version comes with a few presets so you don't have to spend a lot of time tweaking parameters to start playing around. I also have some other videos that explain the new interface a little more in depth.

Interesting stuff... btw, what's with the huge ass phone adaptor cable on the devs phone?
