4 more days, until you can finally:

RENDER YOUR PROJECTS:

Code:
-- Ultraschall-API demoscript by Meo Mespotine 29.10.2018
-- 
-- render a project to numerous audio-file-formats(in this example: flac, opus, mp3, wav)
-- see Functions-Reference for more details on the parameter-settings, given to the functions,
-- as well as other formats
--
-- opens file-dialog to select project-file. after selection, it will show an input-box, where you enter
-- the render-filename with path. file-extensions will be given by Reaper's rendering-process automatically

dofile(reaper.GetResourcePath().."/UserPlugins/ultraschall_api.lua")

-- Select Input and Output-files
retval, projectfilename_with_path=reaper.GetUserFileNameForRead("", "Select Project-File", "*.rpp")
if retval==true then
  retval2, renderfilename_with_path=reaper.GetUserInputs("Please give filename+path of the target-render-file.", 1, "", "")
  else
  reaper.MB("No projectfile selected. Quitting now.", "No projectfile Selected", 0)
  return
end

if retval2==true then
  -- Create Renderstrings first, for Flac, Opus, MP3(Maxquality) and Wav
  render_cfg_string_Flac = ultraschall.CreateRenderCFG_FLAC(0, 5)
  render_cfg_string_Opus = ultraschall.CreateRenderCFG_Opus2(2, 128, 10, false, false)
  render_cfg_string_MP3_maxquality = ultraschall.CreateRenderCFG_MP3MaxQuality()
  render_cfg_string_Wav = ultraschall.CreateRenderCFG_WAV(1, 0, 0, 0, false)
  
  -- Render the files. Will automatically increment filenames(if already existing) and close the rendering-window after render.
  retval, renderfilecount, MediaItemStateChunkArray, Filearray = ultraschall.RenderProject_RenderCFG(projectfilename_with_path, renderfilename_with_path, -2, -2, false, true, true, render_cfg_string_Flac)
  renderfile1=Filearray[1]
  retval, renderfilecount, MediaItemStateChunkArray, Filearray = ultraschall.RenderProject_RenderCFG(projectfilename_with_path, renderfilename_with_path, -2, -2, false, true, true, render_cfg_string_Opus)
  renderfile2=Filearray[1]
  retval, renderfilecount, MediaItemStateChunkArray, Filearray = ultraschall.RenderProject_RenderCFG(projectfilename_with_path, renderfilename_with_path, -2, -2, false, true, true, render_cfg_string_MP3_maxquality)
  renderfile3=Filearray[1]
  retval, renderfilecount, MediaItemStateChunkArray, Filearray = ultraschall.RenderProject_RenderCFG(projectfilename_with_path, renderfilename_with_path, -2, -2, false, true, true, render_cfg_string_Wav)
  renderfile4=Filearray[1]
  
  -- show the filenames of the rendered files
  reaper.MB("The rendered files are:\n\n1: "..renderfile1.."\n2: "..renderfile2.."\n3: "..renderfile3.."\n4: "..renderfile4, "Rendered Files",0) 
else
  reaper.MB("No outputfile Chosen. Quitting now.", "No outputfile Selected", 0)
end

--ultraschall.ShowLastErrorMessage()


even the current active project(needs to be saved first):

Code:
-- Ultraschall-API demoscript by Meo Mespotine 30.11.2018
-- 
-- render the current project either from time-selection or as a whole to numerous audio-file-formats(in this example: flac, opus, mp3, wav)
-- see Functions-Reference for more details on the parameter-settings, given to the functions,
-- as well as other formats
--
-- checks, if the project needs to be saved first(as an unsaved project can't be rendered using my approach due API-limitations). 
-- After that, it will show an input-box, where you enter the render-filename with path. file-extensions will be given by Reaper's rendering-process automatically

dofile(reaper.GetResourcePath().."/UserPlugins/ultraschall_api.lua")

-- Check if file needs to be saved, otherwise give script Output-filename with path
if reaper.IsProjectDirty(0)==0 then
  retval2, renderfilename_with_path=reaper.GetUserInputs("Please give filename+path of the target-render-file.", 1, ",extrawidth=200","")
  else
  reaper.MB("Project must be save first. Quitting now.", "Project not saved", 0)
  return
end

if retval2==true then
  -- Create Renderstrings first, for Flac, Opus, MP3(Maxquality) and Wav
  render_cfg_string_Flac = ultraschall.CreateRenderCFG_FLAC(0, 5)
  render_cfg_string_Opus = ultraschall.CreateRenderCFG_Opus2(2, 128, 10, false, false)
  render_cfg_string_MP3_maxquality = ultraschall.CreateRenderCFG_MP3MaxQuality()
  render_cfg_string_Wav = ultraschall.CreateRenderCFG_WAV(1, 0, 0, 0, false)
  
  loopstart, loopend = reaper.GetSet_LoopTimeRange(false, false, 0, 0, false)
  if loopend==0 then loopend=reaper.GetProjectLength() end
  
  -- Render the files. Will automatically increment filenames(if already existing) and close the rendering-window after render.
  retval, renderfilecount, MediaItemStateChunkArray, Filearray = ultraschall.RenderProject_RenderCFG(projectfilename_with_path, renderfilename_with_path, loopstart, loopend, false, true, true, render_cfg_string_Flac)
  renderfile1=Filearray[1]
  retval, renderfilecount, MediaItemStateChunkArray, Filearray = ultraschall.RenderProject_RenderCFG(projectfilename_with_path, renderfilename_with_path, loopstart, loopend, false, true, true, render_cfg_string_Opus)
  renderfile2=Filearray[1]
  retval, renderfilecount, MediaItemStateChunkArray, Filearray = ultraschall.RenderProject_RenderCFG(projectfilename_with_path, renderfilename_with_path, loopstart, loopend, false, true, true, render_cfg_string_MP3_maxquality)
  renderfile3=Filearray[1]
  retval, renderfilecount, MediaItemStateChunkArray, Filearray = ultraschall.RenderProject_RenderCFG(projectfilename_with_path, renderfilename_with_path, loopstart, loopend, false, true, true, render_cfg_string_Wav)
  renderfile4=Filearray[1]
  
  -- show the filenames of the rendered files
  reaper.MB("The rendered files are:\n\n1: "..renderfile1.."\n2: "..renderfile2.."\n3: "..renderfile3.."\n4: "..renderfile4, "Rendered Files",0)
else
  reaper.MB("No outputfile Chosen. Quitting now.", "No outputfile Selected", 0)
end

ultraschall.ShowLastErrorMessage()



and yes, you saw right: the render-functions return the filenames of the rendered files!
