I don't have any of these synths! But I will probably get a K3 sometime, I like those. Xpander is cool but doubt if I'd go for the asking price these days. I have heard of them, of course, but the rest of these synths I don't know much about.
Kawai: K1, K3
Lexicon: PCM-70
Oberheim: Matrix 6/6r, Xpander/Matrix 12
Yamaha: (2x) DX21/TX81Z, FB-01
Yes! I had it on an old Mac I acquired years ago, but never spent the time to figure it out. Then that Mac needed a new drive and I never bought a proper copy of M until now. In the mid-80s this company Intelligent Music was started by Joel Chadabe in Albany NY. David Zicarelli (now Cycling 74) created M and Jam Factory, and the same team also made a rhythm editor called "Upbeat" which I would love to find. Supposedly, much of their MIDI code was contributed from David Oppenheim, of Opcode. After IM folded David went to Opcode and developed Max. One can definately see the lineage of M to Max, it and Jam factory look like sprawling, ancient Max patches. Even the documentation has the same terseness and typesetting as the Max/MSP/Jitter manuals. David even released a new version of M this year which ports it to Intel Macs and now uses coremidi. I saw posts from him in some blogs a while back where he said he is gradually porting the source for Jam Factory and Upbeat too - but they are not a real priority. Might get released eventually, might not. I certainly hope they do! If I like M I might well buy the current version, which they offer for $74US, I have been on the fence about it.
All disks. I don't have any MPU-104 to check them out with, but they are not too scarce.
Yes, I did dl the last versions of SVP. I was so psyched because I owned SVP before but my keydisk got ruined. I still would have liked to see Vision v1.0. SD I have on my Falcon but didn't use, but might now that I have a sampler (FZ1). SDI for Mac would have been cool too, just as part of the Plus project here. I have a fair amount of Mac software but the only 68k stuff I had is later FAT code for System 7 or so, so I have never really used my Plus before. It's great to have some software to play with on it!
As it turned out I had a crushing work week of 14-16 hour days, and a short weekend - so I am going to try to get some audio play time going on here!
