Oms Recognition Problems, OMS recognition problems Options

[chet]

Dear Mac-music readers-

I am currently setting up Pro Tools LE version 5.1.1 on a Mac G4 dual 1ghz. I installed the Pro Tools software and was attempting to configure OMS when I ran into a snag. I have my midi devises set up in a chain as follows: Digi 001 out to Yamaha DX7II in, DX7II out to Emu Orbit in, Orbit thru to Kurzweil MicroPiano in, MicroPiano thru to Alesis NanoBass in, Nanobass out/thru to Digi 001 in. When I go through the steps to configure my studio in OMS, it recognizes my Digi 001 and the first devise in my chain, my controller, a Yamaha DX7II, but nothing beyond that. If I use the “customize” feature in OMS and manually enter the other devises, and then try the “test studio” feature in OMS, I get no midi response from the devises. Is the chain that I have stated non-functional or is there some setting on one of the devises that I need to change? I will eventually be using Emagic’s Logic Platinum 5 as my sequencer, but I first need to get my midi devises to communicate. Any input you could provide would be greatly appreciated. Thank you for your time.

Sincerely,

Chet

You're chaining way too many MIDI devices on one port only. Try with 3 at most for the others you'll need a second port.

The MIDI standard works ok up to 3 devices or less on the same port (even if all channels are not used). After 3 devices roblems arise, timing goes bonkers…

Note that the DX7 as an early MIDI device can be a bit a bit uncooperative. (not transmiting data etc).

Hope it'll help
