I'll reply just so you're not lonely, but I don't have much to add. :-)
I actually got to beta test Samplitude before it's release. Since I was big on Amiga/midi/Studio16 back when Samplitude was brand new I offered to do some testing. It wasn't 100% complete and I only had a minimul text doc and questions to the author to guide me. Memory is faint, but I think I recall it didn't have some things implemented yet that I really needed, but I thought it had lots of potential. I haven't used it since the beta and it was shortly before I decided to move more stuff to PC, so I'm no help at all. But I hope you enjoyed the "way back machine." :-)
