After posting the previous article proclaiming that the MIDI tools are availible via APDA, I have received mail saying that you cannot in fact get them from APDA. They are claiming that it's still in development and that they don't yet have the masters. I really got the impression from the Apple guy I talked with that they were availible, so maybe APDA just haven't geared up. In any event, I think that if they're not availible right now, they will be very shortly. I hope I haven't inconvenienced too many people. -- Frank Owen (fjo@ttrdf) 312-982-2182 AT&T Bell Laboratories 5555 Touhy Ave., Skokie, IL 60077 PATH: ...!att!ttrdf!fjo

In lieu of actually getting the MIDI tools, I wonder if somebody with the information might want to give us some idea to what the details of using the package are like, for a programmers point of view. In particular, what kind of calls do you make to do the MIDI I/O? Is it easy to convert an existing MIDI application that uses a raw SCC interface to the new package?

Well, I just called APDA and they said "it IS availible and IS SHIPPING"!! So, you can get it. Now, are there any APDA members out there who'd be willing to buy a copy for/with me? -- Frank Owen (fjo@ttrdf) 312-982-2182 AT&T Bell Laboratories 5555 Touhy Ave., Skokie, IL 60077 PATH: ...!att!ttrdf!fjo

> Now, are there any APDA members out there who'd be willing > to buy a copy for/with me? This brings a question. Why do I have to pay APDA so that I can pay to buy things from them. For instance, all I want to buy is the commtoolbox and the MIDImanager stuff. I bought Lightspeed at the University Computer Shop, and get most other things at cost from a guy I know who runs a Computer Store. Now if I go into my University Computer shop and say, I want the commtoolbox and MIDImanager by Apple, I think I'll get a blank stare. (I got enough of a blank stare when I asked for Lightspeed C, which seems to have undergone too many name changes, so I'll refer to it as that C compiler which isn't MPW) If I join that other Mac Programming Association can I buy the MIDImanager and commtoolbox? What is the name of that other one anyways, TechAlliance? Am I going to get anything else besides the priviledge of buying from APDA by joining APDA? The magazine they put out sounds like a bunch of promotional drivel, which I get enough of as it is. David.. --- * Origin: Future Vision: Progressive & Innovative (1:250/428)

I've just converted an application that was using the MacTutor (Kirk Austin) MIDI drivers to run under the MidiManager. The hardest part for me was that the MidiManager really wants to run at interrupt time, and all my code assumed that I was going to be polling the driver from my main event loop. This means that I had to play games to find my globals and that I couldn't move memory, etc. This is all standard driver/interrupt stuff, but I had never done it before. Basically the calls to the MidiManager are pretty simple. A call to Initialize, a call to "SignIn" your application, calls to add and subtract virtual ports, calls to find out about other applications ports and connect and connect to them, a call to write a packet, etc. Data comes and goes in MIDIPackets: MIDIPacket = packed record flags: BYTE; { what type of packet } len: BYTE; { length of packet including 6 byte header } tStamp: LONGINT; { in local time } data: packed array[0..250] of BYTE; end; MIDIPacketPtr = ^MIDIPacket; When you add an input port you pass the address of a "readHook", which is called at interrupt level when midi packets arrive. The MidiManager only reports completed packets. It also "completes" any packets sent with running status. You may write data to output ports at interrupt time or from the main event loop. The MidiManager comes with source for a few simple applications, some in Pascal, some in C. I'd be glad to answer any questions, if I can. -- _______________________________________________________________________________ Chris Muir | "There is no language in our lungs {hplabs,pacbell,ucbvax,apple} | to tell the world just how we feel" !well!cbm | - A.

Queston: Can I run MOTUs Performer 3.0 under Multifinder concurrently with an application that uses the MIDI manager routines without a) crashing b) causing really bizzarre music? Does Performer 3.0 use the MIDI manager if present? Thanks! ____________________________________________________________________ Have a day. :^| Murat N.
