(1) I am not familiar with delphi or MIDICOM3, so I can't help you 
there. Pre-Windows, I used to read midi data direct from I/O ports 
on midi cards. Windows changed all that around so that you need tons 
of overhead to program midi data directly. My hat goes off to you if 
you can master midi programming in today's computing environment.

(2) I am not sure you need to buy any MMA publications; there are a 
number of resources on-line.

(3) I searched for MIDICOM3 and one site reports it was designed for 
Windows 95. I saw your discussion at KVRAudio (Dec '06) and it looks 
like you've got a couple of people that are familiar with MIDICOM3.

(4) Your code reminds me of where I was with midi programming--I 
stuck my asm routines (reading midi I/O) in Borland Pascal. (Wasn't 
Delphi Borland's answer to Microsoft's "Visual XXX" programming?) 
Though I have't looked at the libraries in MIDICOM3, my guess is 
that there are clock structures of some type [pardon the pun]. I 
assume there are midi streaming functions as well. I am not sure 
that you have done so far, but I suggest (if you haven't done so 
already):

(a) Build a program that send out data at regular intervals--such as 
a midi metronome.

(b) Once succesful, convert the program to send out midi timing 
bytes (Is it F8?) on a regular basis.

(c) Program some keys to insert start and stop bytes into your 
midistream. Test by setting your drum machine to external clock.

(d) Once that's working, reverse the process to READ incoming clock 
data FROM the drum machine. To start I'd display status: START/STOP. 
Then I'd develop a routine to count clock bytes to display current 
tempo.

(e) I would thing that once you've done these things, you will have 
developed the basic code you need to integrate clock functions into 
your own software.

Hope this helps.
