The following table shows the waveform output driver messages (WODM_XXX).
| Programming element | Description |
|---|---|
| WODM_BREAKLOOP | This message is used to request a waveform output driver to break an output loop that was created with a WODM_WRITE message. |
| WODM_CLOSE | This message is used to request a waveform output driver to close a specified stream that was previously opened with a WODM_OPEN message. |
| WODM_GETDEVCAPS | This message is used to request a waveform output driver to return the capabilities of a specified device. |
| WODM_GETNUMDEVS | This message is used to request a waveform output driver to return the number of device instances that it supports. |
| WODM_GETPITCH | This message is used to request a waveform output driver to return the specified device's current pitch multiplier value. |
| WODM_GETPLAYBACKRATE | This message is to request a waveform output driver to return the current playback rate multiplier value for the specified device. |
| WODM_GETPOS | This message is used to return the current position within a stream. The position is relative to the beginning of the waveform. |
| WODM_GETPROP | This message is used to reqest the properties of a waveform ouput driver. |
| WODM_GETVOLUME | This message is used to request a waveform output driver to return the current volume level setting for the specified device or stream. |
| WODM_OPEN | This message is used to request a waveform output driver to open a stream on the specified device. |
| WODM_PAUSE | This message is used to request a waveform output driver to pause playback of a waveform. |
| WODM_PREPARE | This message is used to request a waveform output driver to prepare a system-exclusive data buffer for output. |
| WODM_RESET | This message is used to request a waveform output driver to stop sending output data and return all output buffers to the list. |
| WODM_RESTART | This message is used to request a waveform output driver to continue playback of a waveform after playback has been paused with WODM_PAUSE. |
| WODM_SETPITCH | This message is used to request a waveform output driver to set the specified device's pitch multiplier value. |
| WODM_SETPLAYBACKRATE | This message is used to request a waveform output driver to set the playback rate multiplier value for the specified device. |
| WODM_SETPROP | This message isused to request a waveform output driver to change properties. |
| WODM_SETVOLUME | This message is used to request a waveform output driver to set the playback rate multiplier value for the specified device. |
| WODM_UNPREPARE | This message is used to request a waveform output driver to remove the buffer preparation performed in response to WODM_PREPARE. |
| WODM_WRITE | This message is used to request a waveform output driver to write a waveform data block to the specified device. |
