I've exchanged a few emails in the past, and found him very approachable - but do bear in mind English is not his native language! Also, he must be getting on a bit now ... at least in his thirties :P You might also like to chat with Alan Calvin (Cal) who is working on Yoshimi, a derivative of Zyn. and doing special work on improving the jack interface. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.
