While looking here* is there any command for reaper which can render only the first bar of the project?
Example use case: Assuming you just created some 1 bar loop, for playing around or experimenting something, some technique and having lots of such projects on your harddisk, it could be an interesting way quickly getting their .wav representations, you could listen to them later, also without having to start reaper, plus stuff you might have forgotten. For sample pack or beat creators this could be interesting as well. In case of beat creators, replace 1 bar with 4 bars. You could export each stem separately, plus the master mix.
Most flexible would be this command if you could say:
start rendering from bar x, for duration of y bars.
My example above would have: x=1, y=1
For beats: x=1, y=4
