MIDIIO Sample Application ------------------------- *** Application Features *** View MIDI input messages in raw form or with text descriptions. Send MIDI messages using the mouse or from dialog controls. Select MIDI input and output devices from the application. Run multiple instances to demonstrate MIDI device sharing between applications. *** Notes *** Source demonstrates implementation of MIDI device selection and sharing techniques, and simple data input and output. Wrapper functions encapsulate low-level MIDI API's, handle errors and simplify application code. Macros provided for building MIDI messages. Manifest constants describe MIDI message protocol. Easy to build and run since no DLL callback required. The MIDI data viewer filters out MIDI Timing Clocks, Active Sensing, and System Exclusive data. The received data is not time-stamped. Due to the performance limitations of window message callbacks, the method employed by this sample of receiving data may result in loss of data under certain conditions. For an example of how to implement the more reliable method using a DLL callback, see the MIDIMON sample included with the Windows 3.1 SDK. The Sound Blaster 1.0 driver doesn't allow simultaneous MIDI input and output, so if the input is already in use, you won't be able to select the output, and vice versa. Some MIDI drivers such as the driver for the Advanced Gravis Ultrasound may perform long operations when being opened or closed. In such a case, select the Always Keep Open menu items in the Inputs and Outputs menus so that MidiIO will not release the input and output devices when it loses activation. The result of sending MIDI All Notes Off depends on the implementation of the MIDI driver being used. For example, the MediaVision Pro Audio Spectrum 16 driver sends All Notes Off and Reset All Controllers on all 16 channels. The low-level MIDI API's used in MIDI.C are documented in the Windows 3.1 SDK Multimedia Programmer's Reference and Programmer's Guide. The information is also available in WIN31MWH.HLP, a Windows help file provided with the SDK.
