This means there are essentially no differences between the units - 
apart from the waveforms available. 

This is really good news - it means that conversion should be >really< 
easy - no perl required. We can fix this in a text editor!!

For the audity extreme however, there will be a little fuss involved - 
we'll need to convert one number to another, though it's just 
subtraction. It's still a great deal simpler than I imagined.

The document on the site, while invaluable, takes us only halfway - 
it's designed for implementing an editor program rather than explaining 
the format of a patch sysex dump from the emu. No problem though. Now 
we know what to look for, we look at the sysex and work out where the 
important numbers in each layer are kept. This should be pretty trivial 
to find in an individual patch dump, though how it looks in a mass dump 
may be different from that.

Pity - it looks like the planet phatt will be a lot more complicated to 
convert. One step at a time, I suppose. (There's also the orbit, though 
at that point, we will be drowning in patches :>) It should not be too 
painful especially after the extreme is converted, and I have a planet 
phatt I can get the patches from.

Guys, this pdf is of interest to anyone using a software sequencer to 
control their units. In logic audio, at least, you could build 
environments that do as ultra cool stuff as turning of soloing in 
layers (way cool), switching samples on the fly, and altering the 
effects <sigh>. I miss logic...

We can find the audity ROM ids from the patches themselves, when we can 
find them. We already have the xl-7 rom ids.

I have enough experience with perl to know what it can do, but not 
enough to actually write the script. I >do< have a number of friends I 
can hit up, especially for something as ridiculously simple as finding 
a number, and subtracting 287 from it, in hex. 

All we will need now are the Audity Presets. I've just joined the A2k 
and audity 2000 mailing lists. Hopefully, someone will be kind enough 
to help me out. If anyone here can rustle them up, send them to me, at 
biz at groovetronica.com, I'll do my part for the 'cause' :>

p.s. Sean, Aaron - thanks guys for the awesome upgrade! I can't wait to 
get home tonight...
