Attached is the Delphi version of the AWAPI library, Build 7. The only
difference from Build 6 is that all PChar parameters have been changed
to const PChar parameters. I tested this Build 7 library earlier today,
using a version of Sample 2 that was written for Build 6. (Sample 2
makes a lot of use of string parameters.) It seemed to work fine.

Sample 2 uses an infinite loop, with aw_wait providing the time interval for the
callbacks to aw_query and the CellBegin and CellObject events. The Delphi sample
program leaves it open how to break out of the loop. The best method is to make
Button2 a 'Stop' button. But Button2 doesn't work in the usual way, giving you the
false impression that the Aw.dll is preventing the window from regaining control,
because as soon as you wait for the callback events to occur, the Sample 2 window no
longer responds to your mouse and keyboard. Enabling the Form's Boolean Stop field,
and placing a 'break' test inside the loop isn't enough. You must also put
'Application.ProcessMessages' in the loop ahead of the 'if Stop then break' test. Now
pressing the Stop button stops the endless replaying of the 10 midi files.
