Wow Need some optimization on echo/reverb, because voice gets distorted when a key is hold for long time. Other then that, great app.

Ben Berlin

Opus 1 Very nice app only thing I would change would be adding a song feature so you could play along.

Nazmi Nazmi

Im a pipe organ lover and then i found this~ loved it so much

Travis Tomlinson

Horrible sound quality

Inspector Javert

Awesome This is the best organ app

Gino Contonelli

So far, very good. Just downloaded it, but it looks very promising.

Chip Altman

Flat! I loved this app until I realized all the pitches are a little flat.


Polyphonic capacity is unexpected Ability to play multi note chords is impressive.

Jonathon Binnekamp

Very good Very very good, same with the pitea app, the main thing it needs is some realistic (and editable) reverb because although the sound files are of sufficient quality for a mobile device, the lack of reverb is a real bummer. Not sure how difficult this is to implement, but I hope you give it a try! Thanks very much anyways, fantastic job :)

Chukwunonso Offiah

Cool It's really good n functioning

Martin Stacey

Fantastic and fun! A real suprise and lot of fun, very well made. The baroque sound is pure magic and even the hint of a mild temperament makes it irresistable!

Tom Phillpotts

Beautiful. The closest thing to a real church organ in your pocket! Great peice of software, well made, beautiful sound samples.

Kim Smith

Surprisingly Great. I'm sure many have tried piano or keyboard apps but this will open up a brand new experience. Very Educational!

Simple Does what it says

Pipe Organ in a Pocket! Great app, tons of potential. Great for when you are "on the go" and need to pound out a melody line for someone. Even better for use with a MIDI keyboard. It isn't "Hauptwerk," but you can't get much better for what it is!

Paula Wynn

Err....0 stars Foreign only. Blehh! Force closes when I use translator. What the heck?

A Google User

Low Latency Sure would be nice to try the low latency feature on other devices with Jelly Bean. The Galaxy Nexus isn't the only device with 4.1.

A Google User

pretty good I like the way the instrument of the pipe organ plays, however even with my samsung s 2 it's hard to maneuver the keyboard. I like the option of having more keys but unfortunately it makes the keys smaller. and I wish it had an option to automatically put the bass pedals, on to your keys while playing. all in all a good app but unfortunately, my hands are too big to play any decent music.

A Google User

Very good app! I'm going to install on my tablet.

A Google User

Can't hear sound! What is the problem?

A Google User

Great app The app is great, but i would give 5 stars if there were different types of organs. Also more registrations would be nice. 32' please :D

A Google User
