Module Name:

|
|
|
LinksExtreme.cpp
|
|
|
|
Abstract:
|
|
|
|
This app cannot recognise the MIDI technology flags properly.
|
|
The app's internal logic cannot handle the last two technology
|
|
flags viz. MOD_WAVETABLE and MOD_SWSYNTH. If these flags are
|
|
returned by the call to MidiOutGetDevCapsA API, the app shows
|
|
a messagebox and restarts after playing for a while.(AV's).
|
|
|
|
Notes:
|
|
|
|
This is specific to this app.
