MPL scripts thread

mpl · 02-23-2017, 05:59 AM

Hi.
Feel free to discuss here any script I wrote.
All scripts are easily downloadable with awesome ReaPack manager extension by Christian Fillion (cfillion). For any special needs you can take a look at source code.

There are a lot of stuff so here is very short overview of some:

Align takes - Aligning takes based on their level energy matching
Import Session Data - port of ProTools and StudioOne feature, parse RPP and allow to import some data without actual opening source project
InstrumentRack allow to quick access all instruments in current project
InteractiveToolbar an script displaing some information about different objects, also allow to edit them quickly without walking through menus and windows.
LearnEditor / Modulation editor - quick overview current parameter MIDI/OSC mappings and parameter modulation
Mapping Panel - advanced macro control beetween plugin parameters in project, support multiple linking, formulas and fixed auto learn macro controls to controller.
Peak Follower tools - utilities for creating envelopes based on audio signal
Quantize Tool - advanced groove quantisation of item positions, notes, stretch markers or envelope points to each other, also support SWS grooves
RS5k manager - handling ReaSamplomatic5000 instances on selected track
Sampling tool - dump played MIDI notes from some instrument to a RS5k sampler
SendFader - advanced sends control
Spectral editing tools - advanced spectral edits manipulation
StretchMarkerGuard - algorithm for transient protection peak-based stretch markers
Tempo detection - first available algorithm for tempo detection using pure lua + ReaScript API
VisualMixer - port of Izotope Neutron Visual Mixer
WiredChain - allow to route FX in a modular fashion

Some scripts with graphic user interface require ReaImGui extension to be installed (also available with ReaPack). Old and unsupported scripts are placed in additional repository.

Telegram channel for bug reports and issues related to scripts I wrote (actually the fastest way to report things, although you can use GitHub for pull requests and issue reports):

Re SendFader .

First of all, great idea centralizing your scripts thread.

Is this something that can be an option for writing envelopes perhaps?

@mpl
Nice to have a thread to promote your main ReaScript achievements !

You are one of the most generous and dedicated scripter out there,
Thank you for all your work... and for sharing !!

Be sure you work DO contribute to make REAPER, and its community, better

I hoep people will find ways to thank you back, you deserve it.

Cheers man !

J Reverb · 02-23-2017, 10:45 AM

broken
mpl_SendFader.lua:1421: attempt to index a nil value (field 'send_t')

sorry just got in

mpl · 02-23-2017, 11:20 AM

hmm check for send table...Added an additional check to this line, hopefully fixed the problem.

J Reverb · 02-23-2017, 11:59 AM

yup fixed ! can we go any faster ?

much better on writing thank you ..

sorry you said it was fixed to 30 .. devs increase ?

mpl · 02-23-2017, 12:09 PM

It is bad idea. It will increase CPU usage way much, especially for scripts with a lot of buffers, internal calculated graphics etc like mine. I tested in empty project, but I have performance meter always open to see thing go right. So higher update frequency can add potential problems with big projects.

musicbynumbers · 02-23-2017, 12:15 PM

Subscribing and your scripts are amazing!

thanks

J Reverb · 02-23-2017, 12:42 PM

can we do a write mode button maybe ? high resolution just for realtime ? is this possible? i know experimental...

and not stable hehe

sonicowl · 03-11-2017, 05:09 AM

mpl, FX window is not closing here after inserting FX. I run action, drag fx to track, and FX window remains open.

mpl · 03-11-2017, 05:36 AM

I just updated and hopefully fixed some strange behaviour (happened to me sometimes).

Yes, works now. But only for drag/drop. Doubleclick on FX reopens FX Browser and keeps it open for every next doubleclick on FX, until last FX is dragged - then it closes. Is that intended behavior?

mpl · 03-11-2017, 06:13 AM

Very strange. If put closing FX browser into exit function it opens FX browser again (wtf?). I placed FX browser closing before exit function, tested and seems fine both for dc and dragndrop.

Arthur McArthur · 03-13-2017, 05:58 PM

Hey mpl,

I'm using "delete bypassed and offline fx from selected tracks" and it's leaving the fx alone but deleting the items on the track

mpl · 03-13-2017, 08:12 PM

Can you attach simple project where it happens (before applying script)?

Arthur McArthur · 03-14-2017, 12:17 AM

Did some further testing and under normal conditions it works fine for me. It turns out the issue comes up when using lb0's "stripper" script. Attached is a project with plugins added by the stripper. Here's a link to the project: https://ufile.io/90ca6

Luster · 06-26-2017, 01:37 PM

Impressive scripts you developed! Thanks for the hard work.

If I may make one proposal for those:
mpl_Toggle show tracks if edit cursor crossing any of their items.lua
and
mpl_Toggle show tracks if time selection crossing any of their items.lua

Right now the scripts ignore the hidden state of tracks before running. When you have some backup (archived) or utility (e.g. video) tracks which you don't want to use or see - they get visible with those scripts. Even those without items in it when "backtoggling". I believe I could make a custom action with the me2beats "restore saved track selection" scripts but believe that this functionality is better integrated directly in the script - it feels more complete then IMHO.
What do you think?

mpl · 06-26-2017, 02:06 PM

This goes impossible since script doesn't know which tracks you hidden for different purposes and which were hidden by this script (it can be remembered, but I don't think it is a good idea for such a simple script). So from script side I can add excluding tracks via manipulating with track name. For example I can prevent script to show/hide tracks, started from "*" symbol in their names.

Luster · 06-26-2017, 02:45 PM

Well, I believe it is possible.

I will try in Cycle action editor then - something like this:
1. Select all tracks (which are visible)
2. Save track selection

3. your script

4. Hide all tracks
5. Recall track selection and make visible

Maybe we misunderstood a little.

Edit: Hmm, still the script would unhide those hidden not necessary tracks. Maybe the simple point is that script should just hide tracks.

Edit2: Got it working somehow with the Cycle Action Editor but still it unhides unnecessary tracks. When looking through all those script code lines I try to understand but no chance. This isn't my territory.

Gianfini · 06-28-2017, 01:40 AM

Great idea to start this thread about your top scripts... do you have any plan to update/adjust the Quantize tool so that it can use the "snap offset" to align items instead than using only the beginning of the item?

It would be greatly beneficial, because at the moment I cannot use it without this feature

thanks in advance

Hi Mpl

"Script: mpl_Delete bypassed and offline fx from selected tracks.lua"

This script is working only for bypassed fx here. Nothing happens for offline fx.

mpl · 07-05-2017, 03:00 PM

I recoded "delete bypass/offline fx" completely, should works safe and faster now (used direct SWS APIs).

mehmethan · 07-05-2017, 06:01 PM

..._Delete bypassed and offline fx from selected tracks.lua:24: attempt to call a nil value (global 'msg')

I'm having this error now.

Reaper 5.50 x64 SWS 2.9.4 win 10 - 64 bit

note : I have 8 fx on the selected channel. first fx is active, the othe 7 are offline

mpl · 07-05-2017, 08:20 PM

It is version issue, I fixed it yesterday, but seems Github didn't refreshed yet (the code on Github is right). The final version is 1.12, I think it will go away after next update.

Don Solaris · 07-06-2017, 11:45 AM

Mihail, any chance of adding / modifying the 'List next sample in directory for RS5k' script for the OSX Mavericks?

I have this project with hundreds and hundreds of drums, and as you probably know, RS5k on OSX doesn't let you move cursor keys for the previous / next sample. Instead you have to use mouse and click manually which for near thousand samples would mean clicking it thousand times. Yikes!

I was happy to see your script and thought i found the solution to the problem. But for some unfortunate reason, the script doesn't move to the next sample. I have the latest Reaper 5.40 64bit running on OSX Mavericks. I have Reapack up and running. No issues there.

Hey, I'd be glad to toss in some cash for the beers if you can make that script work on Mavericks (FTW!).

Cheers!!!

mpl · 07-07-2017, 11:35 AM

Don Solaris,
didn`t heard about any issues with this script (it almost doesnt touch any possible win/osx differences, I`m on windows) and about mentioned issues with listing samples in RS5K.

Maybe I didn`t named it properly (as usual, unfortunately my English is still bad). "List next/previous sample in directory for RS5k" was designed to list samples for RS5k instance on selected track (like you play and hear arrange and list samples without actual opening track FX chain and selecting RS5k instance). In case you want to replace native function seems you need different script. You can test this piece of code below. If it works for you, I can make version for ReaPack for assigning with shortcut or mousewheel (but bug report to Justin or Schwa of course better).

(test_List next sample for focused RS5k)

Code:

  function main()
    local ret, tracknumberOut, _, fxnumberOut = reaper.GetFocusedFX()
    local track = reaper.CSurf_TrackFromID( tracknumberOut, false )
    if not track then return end
    ret, fn = reaper.TrackFX_GetNamedConfigParm(track, fxnumberOut, "FILE0")
    if not ret then return end
    fn = fn:gsub('\\', '/')
    
    path = fn:reverse():match('[%/]+.*'):reverse():sub(0,-2)
    cur_file =     fn:reverse():match('.-[%/]'):reverse():sub(2)
    -- get files list
      local files = {}
      local i = 0
      repeat
      local file = reaper.EnumerateFiles( path, i )
      if file then
        files[#files+1] = file
      end
      i = i+1
      until file == nil
      
    -- search file list
      local trig_file
      if #files < 2 then return end
      for i = 2, #files do
        if files[i-1] == cur_file then trig_file = path..'/'..files[i] break end
      end
      
      if trig_file then 
        reaper.TrackFX_SetNamedConfigParm(track, fxnumberOut, "FILE0", trig_file)
        reaper.TrackFX_SetNamedConfigParm(track, fxnumberOut, "DONE", "")
      end
  end


  reaper.Undo_BeginBlock()
  main(track)
  reaper.Undo_EndBlock('test_Next focused RS5k smpl', 1)

Don Solaris · 07-09-2017, 01:24 AM

That works perfectly!

And i've sent you 30 notes for some beers.

Can you just tell me which line to modify to have 'list previous sample' option as well? So that i can add that to the other script.

Cheers!

mpl · 07-09-2017, 02:21 AM

Big thanks for donation!

Check ReaPack for:
- mpl_List next sample in directory for focused RS5k
- mpl_List previous sample in directory for focused RS5k
- mpl_List samples in directory for focused RS5k (MIDI, OSC, Mousewheel)

These scripts are also use wrapping indexes (so they getting last sample in directory if you trigger 'list previous sample' for the first sample in directory). The only thing is for some reason script for mousewheel binding works only if you have opened RS5k but common focus on arrange. MIDI/OSC binding works ok for me:

EvilDragon · 07-09-2017, 04:23 AM

Don, finally awesome workflow for you. Enjoy!

Don Solaris · 07-09-2017, 07:52 AM

Yes! And for all the others who have suffered with RS5k on OSX.

RS5k is an excellent sampler, particularly for drums - due to simplicity and fast workflow!

And thanks to Mihail!

Gavinchan · 07-09-2017, 09:02 AM

Hi, big fan of your work!

I'm having trouble with the "mpl_Select tracks with SWS Notes" script available in the ReaPack repository. It doesn't seem to work at all.

The trouble appears to be in actually finding and matching the track_guid string in the project file.

I've done some crude debugging with my very limited lua coding knowledge and it seems that it only works if you limit the track_guid to the first 11 characters of the string, then it finds it and selects the correct tracks. I can't for the life of me figure out why it isn't comparing strings correctly. Any help?

mpl · 07-10-2017, 06:55 AM

fixed in Github, reapack index comes later today. String matching pattern issue (or I guess, catching '-' sigh in track GUID as magic character)

mpl · 07-30-2017, 03:59 AM

Added Parameter Modulation Viewer (instead of obsolete Store source for further modulation from last touched parameter and Create modulation link on same track from stored buffer). This allow to quick overview paramter modulation inside selected track.

Also added light MacroControl panel (works for regular FX parameters, track volume, track pan, track width and send volume).

very nice! I did't try it, by what it seems i can see two versions of this: a per track based and a global one. This seems global, per track is like cubase does with quick controls, same 8 knobs holding different parameters per and from the selected track. Sorry if i am saying non sense , i still didn't try , i am excited and i am at 0.01% on reaper knowledge!

Ivannn Bennnettt · 08-01-2017, 05:09 AM

Thank you that you still do this stuff

What about "List Parameters Modulation Viewer" as for whole project as for selected track and item? (and in advance if it possible to do legacy of colour track/item to one)

Quote:

Would be not bad to see param name and value of it under (or above) knob. And I'd found quite handier if "learn" also will work as just touch.

Anyway keep it up!

Anton9 · 08-01-2017, 10:00 PM

MPL,

Thank you for MPL Modulation Viewer, it ROCKS!
Could you please add what NextLevel suggested in that thread?
1. Un-link last touched parameter.
2. Un-link all parameters of current track.

What would be super cool. Is for the script to list all modulation links for current track with a check box next to each that could be used to just bypass certain links.

Thank you!

mpl · 08-02-2017, 08:56 AM

"Remove PM from last touched parameter" added. Versions for focused FX and selected tracks will come later.

Anton9 · 08-02-2017, 10:07 AM

Awesome! Thank you.

Anton9 · 08-02-2017, 10:35 AM

Was hoping that the remove parameter modulation function would be in the MPL Modulation Viewer as a separate button or maybe as right-click on the link button.
Would be nice to have option to not show the delete confirm dialog message.

Thank you

mpl · 08-03-2017, 10:45 AM

Added 'remove PM' for focused fx, selected tracks, removed confirm dialog from last touched fx. Adding to PM viewer seems bad for me to get all stuff up-to-date. Feel free to modify code if you need (buttons, functions, etc).
