you can comment the MB and GetUserInputs line out and set the value to "txt"

-- reaper.MB(Info, "Get Tempo Map", 0)

-- retval_split,input_choose  = reaper.GetUserInputs("Choose File Type", 1, "txt or csv", "csv")
input_choose = "txt"

try changing current function use \\ or / in path:

function read_lines(filepath)

  lines = {}

  --local f = io.input(filepath)
  f = "C:\\Temp\\Files\\mysong.txt"
  repeat

    s = f:read ("*l") -- read one line

    if s then  -- if not end of file (EOF)
      table.insert(lines, ParseCSVLine (s,sep))
    end

  until not s  -- until end of file
         

  f:close()

end

Comment out the lines/actions -- you don't need at the bottom of the script after
set_bar_one_start()


You have the self contained script

that will get the tempo from a media item in the track.

Hello!

I'm currently using the ReaTrak sonic visualiser import bars or beats.lua script which is working great with the export txt file from Sonic Visualiser.

Now, I would like to skip a few in the script steps such as:
- the selection between csv or txt file extension (I will only use txt extension)
- remember the last directory of the imported file or choose a specific directory instead of the default Reaper directory each time the import txt file window appears.
- end the script after the markers have been imported to the timeline/ruler(I don't need the rest of the actions)

As I'm not familiar with coding, are these requests easy to do so maybe I can do them?

Anyway, you did a good job with this helpful script

I did the modifications and test it:

I also removed this line
if not retval_split then goto finish end

with this:
--if not retval_split then goto finish end

and I have an error on the line 163 which is :

s = f:read ("*l") -- read one line


The custom directory doesn't work (it keeps showing the Reaper folder by default).


The following error
...ReaTrak sonic visualiser import bars or beats - Copy.lua:280: bad argument #5 to 'AddProjectMarker2' (string expected, got nil)


is displayed but the markers are imported from the txt.

I mean it's almost working despite the final error box and the customised directory issue

Change to your file:
filetxt = "C:\\Temp\\tempo-map.txt"

ReaTrak sonic visualiser import bars or beats - mod.lua

I've edit the line and the issue still occur.

this is what I have for the moment

function read_lines(filepath)

  lines = {}

  local f = io.input(filepath)
  --f = "c:\\bpm.txt"
  filetxt = "c:\\bpm.txt"
  repeat

  s = f:read ("*l") -- read one line

    if s then  -- if not end of file (EOF)
      table.insert(lines, ParseCSVLine (s,sep))
    end

  until not s  -- until end of file
         

  f:close()

end

Sorry but I can't download your lua file. your link must be broken.

Oh, I forgot to mention that I use the portable version of Reaper if it helps.

Try that
ReaTrak sonic visualiser import bars or beats - mod.lua

The link is working, thank you!

Wow thanks MusoBob, it works marvellously !

Thank you so much, this script is gonna help me saving time!

Let's make some music now!

Thanks guys, this is really useful.

Added bonus - no stems coming down from the tempo markers!

Hi there, maybe this has been answered already, but is there a way to map MIDI notes to markers in audio, so that when the MIDI notes are quantised, the audio will shrink and stretch accordingly keeping the markesrs aligned with the notes ?
