Organ Woes

So for the last few months I have been playing the organ in our ward. The first few weeks were pretty bad as I relearned how to play. I took lessons for a year in high school and then I took a class, but since that ended more than a year ago I didn't even touch an organ until I got called to play. So, needless to say, the first few weeks were not so good. So eventually I got the basics figured out all over again and I decided to get a little fancier- like maybe change the registration in between verses and use the pedals a lot more. For the uninitiated, a basic organ has two rows of keys and pedals that work basically like a piano. But, unlike the piano, for each level you can pull different stops, each of which has a different sound. This is registration. To simplify the process you can preset registrations so you can completely change it just by pushing a button instead of by pulling a bunch of new stops. So I went to do all of this as normal, but when you push the buttons it makes a very loud noise for a few seconds (as if I was playing one of the keys), and it doesn't seem to change the stops. So there went that. So then I was just sticking with the basics, however that didn't end up working too well either. Apparently one of the pedals has a short, so if I have any of the pedal stops pulled it sounds constantly. So now I have just been playing the organ as if it were a piano, but it is just incomplete sounding. All I have to say is that that organ is unlike any organ I have ever played or that I have learned about at all. It is a lot cooler though because it is a pipe organ. And I do like playing the organ, but it's way better when I know how to do what I want and when I can play how I want.
