I had a major in piano,
And a minor in organ, in university, and have worked as an app. tech with two small organ builders. I did at one time do some commerce in pipe organ, and built an organ into my home, after removing it from a church in central Florida, and re-voicing it. I have played many years for several churches.
HOWEVER, I found the additional time spent on organ technique, seemed to limit my ability with piano technique a bit, as they are, of course quite different..In addition you have the added problems with the taking of practice time for two (or more, as I also was a vocalist..) instruments, thereby limiting your time on each one...
I have always felt that the attention to organ was perhaps not wise in that respect, as I always felt piano was my first instrument, and as a choral director for many years, the piano served as a major instrument perferred for me as my voice was never very attractive even in it's best days...
I do believe I would have been a better pianist if I had maintained my attention to just the piano, and not actually "studied" organ.
Any others have any thoughts or historical evidence on this idea?
