Open the Samplitude project file.
Select the MIDI track data you wish to convert to a wave file.
Choose the "Range" menu at the top of the program. Select the "Edit Range" sub-menu within it.
Click on the last option in this menu, "Range Over All Selected Objects."
Select the "Tools" menu at the top of the program. Click the "Track Bouncing" command at the top of this menu. A new pop-up window will appear with the audio conversion settings.
Find the "Generating Options" section in the lower left of this window. Choose the second option, "New Separate Object in Current VIP."
Locate the "Source" section in the upper right of the window. Select the first option, "Only Marked Range."
Press the "OK" button. A new pop-up window will appear as the settings window closes.
Type in the desired file name and location for the wave file that will be created from the MIDI track. Press the "OK" button. The MIDI data will immediately be converted to a wave file. For convenience, this wave file is subsequently imported back into the Samplitude project so that the original MIDI data may be removed or muted.
