Hi Annie, Check out Mark Fontana's Pianocorder Forum at
http://www.voy.com/33099/ . Scan the listings for the ones offering
tapes. There are not that many listings, you can get through the
postings in short order. I would guess the respondents are all located
in the USA. However, you might also try MasterTouch Piano Rolls in
Sydney. They were an outlet for Pianocorder tapes at one time.
I know there are other sources of Pianocorder materials in Australia
too, so maybe you should place a posting on the Pianocorder site for
contacts in Australia.
