Hi chawthorne,
You should be able to using the select tool.
You can export a select range of clips or loops by doing the following:
Click n drag the select range in the time ruler or using the select tool to highlight the desired clip/loop range.
CTRL+click the desired tracks. (including softsynth* outputs & midi tracks)
You may also need to set your musical time snap if things aren't on point.
Go to File>Export Audio and choose your export settings (entire mix or tracks etc.) select/deselect fx if necessary and export to the desired directory.
*If you're not using simple instrument tracks and using midi source tracks be sure to highlight the the VSTi's the midi tracks are routed too or they won't export the audio.
This simple procedure will also automatically convert your midi to audio during the export without the need to convert first.
