Thanks for the update. I've not done much recording in recent years and need to get up to speed with this stuff again.
Might be time to retire the FireWire interface and mLAN drivers...

If you are not dead set on having USB Midi..The Crimson and Command modules still have 5 pin midi...
(for the most part the modules are the same ..Price difference for the kits because of different hardware.)
If there is an update for the modules you could use something else to update them ..I say
if..because Alesis chose to release a Crimson II module with additional samples and kits..
for what amounts to $100.00 more.(the Crimson Kit II, you gain an additional 4 preset kits, 71 new sounds, and an additional 12-inch crash cymbal with a choke.)
If you are looking more towards just using for triggering a Vst or SSD(Kontakt version?) ...consider picking up a new/used DM10 kit..the module is both usb midi/5 pin midi and usb drivers have been available for OSX since.. 2010? when it was released)(OSX 10.7 Lion(64 BIT) was released in 2011..so you'd be good on the usb midi drivers)..
You can pickup a used kit for a good price..plenty of inputs..you can expand it with a TriggerIO...uses individual cables (the newer modules are leaning towards DB25 snakes)
Check Craigslist etc..Locally here DM10X mesh kits are going for 550-600.00...and you found the perfect forum to answer any and all the questions about it.
