How Does Os X Handle Midi Applications?, What midi drivers does OS X use? Options

[danml69]

I was surfing around on the web last night and discovered a driver for OSX by Griffin software http://www.griffintechnology.com/software/...are_serial.html for there gport serial adapter....Of course, my Opcode Studio 4 still needs OMS to operate but it looks like developers are starting to look for serial solutions for OSX

are you sure your studio 4 needs oms?
i used a studio 4 for many years with logic, i can assure you oms was definitely not necassary.
i also use an imate. griffin are extremely reliable, they always release new drivers incredibly quickly, you don't need to worry about them.
as for x, it uses core midi to deal with midi of course. it's going to be a question of the manufacturer of your interface(opcode) providing support(forget it), or core midi providing support(way likely, the guy responsible for core midi just happens to be the same person that wrote oms!), oms always featured built in support for known devices!
obviously, it's not necassary to be worrying TOO much about this at the moment, none of the bl**#y sequencers even work in classic yet!
so, i just purchased 10.2,
very smooth,
faster,
am impressed,
yes, a configurable midi system preference.
not even motu are actually shipping a x.2 app yet...

oh yeah, sorry, but the audiowerk was always a piece of c^*p.

The reason I think the Studio4 needs OMS is that the only way I could get it to work with Logic was to use a Logic/OMS studio set-up. Using the Logic midi engine alone, I couldn't get any midi signals to my rack. The only other sequencer program I used the Studio4 with was Vision, and it required OMS as well. How did you have your Studio4 set-up in Logic?
Oh yeah, the audiowerk2 isn't the best card out there by any means. It was the best I could afford at the time, and I knew would work well with Logic. It was way better than using the built-in audio on my old 7600 power mac.

to use a studio 4 in logic without oms, remove all oms system components, uncheck it in logic, go to the environments' midi layer, create multi instruments for all your midi modules and keyboards.
when you create a new multi instrument you'll notice that the midi channel boxes 1 to 16 are crossed, uncross them to turn the midi channels on.
you can name each instrument and in the part box at the bottom left of logic you can define the port number for the instrument, eg, modem 1 or printer 2, or usb 16!
midi performance without oms is MUCH better. if you need any more help just let me know...
