If you want to change to Mac OS X - and OMS will not be adapted to it by "someone", yes. >I mean,thats not the way >to protect your market . Believe this is not great for you. It's not our decision. There simply is no de-facto standard for multi-port MIDI interfaces on USB, so every manufacturer provided OMS or FreeMIDI drivers. In contrast to the MTP de-facto standard on the serial port, the low-level communication is different for every USB interface - and it is not documented. So even if we wanted to support third-party interfaces on USB, it would be a lot of work or even not possible. If you say we "protect our market" (because we support only our own interfaces directly), then you can also say that all other manufacturers simply don't want to sell their USB interfaces, as they only have OMS or FreeMIDI compatibility and no direct support at all. OMS has become the de-facto standard for USB interfaces on the Mac. There is a proposal from the USB committee, but it arrived too late, so there are already a number of interfaces which don't follow this proposal. USB interfaces on Mac OS X will require an OMS which is Mac OS X compatible - which is currently not the case.
