Default Change output file name for the render command IDs?

I'm making great progress based on advice received here towards writing a script to automate rendering out all my piano midi files. Here's what I have so far:

RENDER = 40015

reaper.InsertMedia("C:/Users/derek/Dropbox/Music/midi/2009/2009 May 25 05.mid",8)

proj = reaper.EnumProjects(1)
reaper.Main_OnCommandEx(RENDER, 0, proj)

track = reaper.GetTrack(0, 0)
I'm experimenting with the render actions. RENDER_RECENT_SETTINGS_AND_CLOSE_DIALOG is the one I ultimately will use once I enumerate all the files I want to render. However, my current question is:

How do I parameterize the output file name for the render? Right now it is untitled.mp3. Although I suppose if I use wildcards there and use the same "use most recent settings" command, perhaps I can achieve the effect I'm looking for.

the relevant functions for render settings are:
GetSetProjectInfo / GetSetProjectInfo_String
for render filename: RENDER_PATTERN

Use my Ultraschall-API for that. There are many things easy to do in Reaper's own API but others hard or not doable at all without ugly hacking.
I already did that stuff for you, so you have rendering full-featured, including render-presets, all checkboxes and dropdownlists in the Render to File-dialog.
And you can customize the render-output-format completely, without having the hassle dealing with BASE64-strings(believe me, it's ugly).


If you have any questions in how to do it, feel free to ask. I made all that stuff for use-cases like yours
