MIDI ReaScript ideas using new REAPERv4.60 API

[spk77]

Hi gofer,
EELed version of your "Smooth CC values" seems to be working great :

Very cool spk77!
It's exactly as expected
Thank you gofer and spk77!

Thanks a lot, I'm going to look into the code, of course, too see what you did there . It seems to be working really good so far . Too bad, it can't go back to original moving the slider back left. But it does proper undo, I figure, with naming in both undo list and menu bar! I never got that to work, so there's another thing I'll have a close look at.

I think you could just allow 14bit, even if the script doesn't touch the LSB messages for these. It won't be 14bit smooth, but at least does the job as good as for 7bit values for the time being.

I do have a vague idea how to do proper 14bit (the problem is that I think it needs to be reliable even if there isn't exactly one LSB with each MSB), maybe if I can find some time.

[Soli Deo Gloria]

Thanks so much, Gofer and Spk77!!!

This thread is becoming a source of midi jewels!

Thanks everybody.

I'll clean/optimize the code (there is some unnecessary code there) and get rid of the arrays - it will be faster that way. I have to study how to "combine" 14bit values. Btw, I'm using Undo_OnStateChange("Smoothen CCs") to add undo points (it adds an undo point when the lmb is released).

Which one is better (in the gif below)?

• old version - get average values from selected CCs only
• new version - get average values from selected CCs + first unselected CC (or last unselected CCs before the selection)

(same behavior in both versions when all CCs are selected in the "last clicked lane")

Well, for me it depends on the need of the moment. Is it difficult/annoying to add an option?

It's difficult/annoying, but I'll add it as an option

Just shift MSB a bit (no pun intented) to make room for LSB and then OR it to add them

MSB << 7 | LSB

Thanks Breeder (I'll poke them with mouse cursor and see if they umm..."combine" )

If I had to choose I'd vote for the old behavior any time. Although the new version definitely has something to it, I find it can stray away from the original "curves" too much.
I have yet another useful behavior to ponder: I made one that leaves the first and last selected event untouched (but uses them to calculate the neighbor value, of course).


As of 14bit, keep in mind that although Reaper's drawn 14bit always come nicely in MSB/LSB pairs on the same timestamp, this is most likely, but not guaranteed to be the case. There could potentially be multiple LSB between two MSB and there could also be MSB without accompaining LSB for whatever reason. So you'll need to check each LSB and calculate it based on the latest MSB in all cases.

You can practice the basic math with pitchbend (shameless plug to add support for pitch messages ). The basic math is the same, but the handling is lots easier, as both MSB and LSB come in a single event. My clumsy take on it is in the pitch section of my "smooth" example script.

Ok, I uploaded a new version (download link is in the post #41):

• not using arrays anymore
• keeps the original curve better (more expected behavior)

Edit: This didn't work correctly when different CC types were selected -> back to the (optimized) original version. Zip file updated.

[spk77]

I hope this works. (Smooth 14-bit CCs - Please test first )

Hard to tell whether 14bit smoothing works mathematically correct, but it looks damn cool . Good work!

Maybe the readout should be a bit different? Instead of "CC 260, Foot Pedal MSB(14-bit) I think something like "CC 4/36, Foot Pedal MSB/LSB(14-bit) would be better (I don't think Reaper calls it CC260 anywhere but the API).

Can't tell you how much I appreciate your work on this.

Thanks gofer,
I had to do some bug fixes (MSB/LSB -pair related), it wasn't working at all at certain conditions. The file is updated again (post#41) - I'll modify the "CC info" part later.

[Stroudy]

I'm really struggling to get this to work.

I'm new to reaper and scripts. I've made a text file, saved it as and .eel and put it in the scipt folder and loaded it in my actions list, but I get a Syntax error - seems to be on the first line.

A lot of the other scripts here seem to be working - and they're amazing! so thanks

Those are Python scripts - save as "scriptname.py".
(You have to install Python if you don't have it installed.)

Ah, I see. Thanks.

Wow, these are great. I thought these were gonna be functions I'd miss from Logic, but no, instead they're better.

Cheers

[gofer]

Thanks
Ah yeah, Python vs Eel example was really sometimes not clear enough without actually reading the code. I edited my posts to make it more obvious which is .py and which is .eel. Alas, most of mine are still not "eelized", I just don't get around to it enough to make real progress.

Anecdote: the "select notes of the same pitch class" script is born directly out of the wish to have Logic's "select similar event" function in Reaper . Initially I planned to do the CC part of it as well, but found I only ever used it with notes, so I didn't...

As of the "select hi/low note in chord" scripts, I probably should also do some to select second highest (second lowest) notes. And versions which unselect the specific notes instead and leave the other notes selected.

If they work - I'm happy wether they're python, eel, newt, reptile or amphibian.

I forgot how much I used "select similar event". I used it to select notes in a played harp gliss using the white keys when making gliss chords or non-maj-min scale stuff.

Selecting other voices in a chord could be good. I got pretty quick in eliminating notes using what Logic had, but "select 2nd, 3rd, 4th voice" would be useful in a tool bar.

I've added email notifications for this thread so I hope to see it on here one day

thanks again

[gofer]

I tried to do "select second lowest" last weekend but ran against some tough walls. I thought it would be as easy as change a value or two, but naah...

But I need to crack it at some point, can't be that hard, it's prolly just that my braincell is so easily confused .
I'm a really bad keyboardist when it comes to chords, so the stuff I play in is mostly close voicings. I long for a function to select all the "second lowest" (the second highest) and transpose them all 1 octave down (up) to widen my voicings fast and easy (or copy them for the extra fat).

This note selector tool (which I use all the time, thank you !) works fine in R4 with pooled items.

Seems this functionality is broken in R5
Still works fine with unpooled MIDI items but when I try to use it on pooled items, nothing happens.

Any chance this could get fixed for R5 please ?

Tested in pre29

I think it works here (v5.0pre29, Win8.1):

(These items are pooled)

Thanks for checking spk77.

I did some more testing now and I noticed it seems to depend on which item is selected (active / editable).

When first item is selected it works, but not when the second one is selected.
When both are selected it also works.

gofer

Thanks for scripts ! Cool!
But in Reaper 5 (pre31,sws 2.7.1) "Select highest note..." and some stopped worked (((.In 4.78 all OK.It's normally? No chance? :-)

[gofer]

Yep. You're getting a message about "positional argument missing", right?

MIDI_SetNote has changed a bit in v5. There has been an argument added (noSortInOptional) to the function. I'm not sure whether it's a bug that Reaper complains about it, as it has "Optional" in the name.
I don't think it would be a good idea to fix the codes here in the thread, because then it won't work in v4.x anymore. Also, Cockos might/should fix the error message coming up on their end (by really making that argument optional). Normally, they don't tend to introduce backward incompatibility.


The fix is easy, though, and you can do it yourself:

For each of the scripts that throws the "MIDI_SetNote misses an argument" error, open it in the script editor (action list -> ReaScript: -> Edit...) and look for lines with "RPR_MIDI_SetNote( yadda, ladda, bla ...)" and simply add in a ", 0" (comma space zero without the "") at the end of the function's arguments, inside the round brackets. You may forget the space, but comma and zero are mandatory. Do this for all "RPR_MIDI_SetNote()", but only for those. Do not change anything else, unless you know what you're doing.

I can't give you a line to copy/paste, as each looks a tad different. But here's an example of how the last SetNote line of "select highest of selected chords" has to look. It's at the very end of the line, so you may need to scroll this code box (I colored the change in red):

RPR_MIDI_SetNote(take, chordProp[k][2], 0, chordProp[k][4], chordProp[k][5], chordProp[k][6], chordProp[k][7], chordProp[k][8], chordProp[k][9], 0)

As said, don't copy paste from here, just place your cursor and type in ", 0" at the appropriate spots. Then hit ctrl+s to save.
If you still get the message, you forgot one. As soon as you did this change to all MIDI_SetNote function calls, the error message is history.

[mezzo]

You're Wizard! :-) Worked!
Great Thanks!

[gofer]

YAY! I (think I) have finally cracked porting "select high(low)est note.." scripts to EEL .

On the way I found out that the above error (number of arguments for MIDI_SetNote) is not an issue in EEL, not sure about LUA, but sure is in Python.

Now the last one of the bunch in this thread that's still not completely eeled is the smooth CC thing. But there's spk77's beautiful slider version of it to be had .
Think I bundle the finished eel versions and put them onto stash. Later today, though. First I'll have to endure some RL duties.


I tried to come up with one that unselects only the lowest note, but am trapped by my own approach as of now. A pity, because "Unselect only lowest" + "Select only lowest" would effectively be "Select only second lowest". Which I was trying to do as well.

[gofer]

Get the bunch of eels from the stash while they're fresh! basket full of fish

Missing is "Smooth values of selected events on last touched CC lane", but spk77 made an awesomized slider version you can find in post #41 of this very thread.


It's a huge pleasure for me to see how some fantastic scripts have spawned during the course of this thread .
Make sure you have a look at spk's hugely enhanced slider version of "Unselect every second event:post #26.
And the magical "MIDI Velocity tool", which actually is able to create ramps not only on velocities, but on CC as well. Get it here.

If I have missed to link some, please shout.

[amagalma]

Is it possible to do a modified version of this script that would work on the currently selected notes and not on a defined pitch, as it currently stands?

+1. I have a need for this type of functionality as well.

...for MIDI notes in time selection. If the time selection isn't set -> range == item start to item end (thanks gofer ).

Updates:

• 5-Sep-2015
  • Now it shows note numbers and note names

Instructions:

• Use mouse wheel to adjust values
• Ctrl+lmb resets the values
• "Pitch" (filter) changes the active note row in MIDI editor.
• Two modes: select or unselect every nth note" (left click to change the mode)

Great! Thanks!
Does the script also work if I have different pitches, like a melody where I want to modify every other note (or is it possible to modify the script in that sense..)?

ole

edit: Or even better would be if a pitch range could be set e.g. '60-72'
edit2: just saw that this functionalty is already requested..
