Probably really a 3.5

Im glad to see a harmonium app, and Ill agree with the previous reviewer about hoping for a slightly more authentic tone. Im am however pleasantly pleased with the developers prompt response to a question I had about the unfortunately buggy nature of the app I downloaded. So techinically I guess Im giving 4 stars for the developers apparent interest in making this app better in the hope that there are some decent improvements with future updates. One thing I would like to see, unless Im confusing a harmonium with a different instrument (such as a pump organ) is some way to control the bellows. If I am mistaken about the way a real harmonium works, then just ignore that last sentance- Id prefer to not be one of those reviewers that for example suggest an app marketed as being for organ sounds include stringed instrument sounds, rather Id just like to see this app turn out as decent as possible.
