Default 'smart' cut of midi items possible?

Hi,

Is it possible to read out the positon of the cursor in an item and the length of Midi notes left and right from the cursor in a script? I asked myself if it is possible to write a 'smart' cut function for midi items, deleting the small chunks left and right of the cursor (see attached pict)?

yes it is possible. You can get midi content of midi item independant of the contect (arrange view, midi editor etc)

Thanks for your answer!

So it would be possible to write a script which compares the length right and left of the cursor and delete the side which is shorter. Or delete one side if it falls under a certain length threshold or a certain percentage.
I'am willing to give a little bounty if someone is interested in writing such a script..

edit:
Before someone start working on that, in the german-speaking part of the forum solger delivered a script which does what I'am looking for
https://forum.cockos.com/showthread.php?t=225694 (in combination with other scripts)

The first version of the Smart split MIDI item script bundle is now up on ReaPack.

After install the following scripts will be available in the [Main] sections of the Action List:
  • Script: solger_Smart split MIDI item (trim left note parts at cursor).lua
  • Script: solger_Smart split MIDI item (trim right note parts at cursor).lua
  • Script: solger_Smart split MIDI item (trim shorter note parts at cursor).lua

The threshold length value determining which (of the left, right or shorter) note parts will be trimmed can be adjusted inside the scripts via the noteLength und noteMultiplier parameters - by default all notes are trimmed.

Very nice Solger!!

I'm wondering if you could make it so that it doesn't open the MIDI Editor? The functionality is great but when splitting items in the arrange window, I don't want to be forced into the MIDI Editor. Is that possible?

Currently it's necessary for the script to work (correctly).
Not sure if it's possible otherwise, but I haven't had time yet to dig into this deeper since I wanted to get version 1.0 ready for release first

I totally get it may be necessary to have it open in order to call ME script commands, but maybe there's a way to (at the end of the script) : Get Active MIDI Focus and Close Active Window or similar or simply use the "Script: Archie_MidiEditor; Close Midi Editor.lua" .

Just brainstorming.

Thanks.

Cheers,

Thanks for the hint. I'll check out the 'close midi editor' script.

I will have a look at this... but a REALLY smart splitter would move the end of the left item to the right of the red-outlined notes-offs, and the beginning of the right item to the left of the red note-ons. That way the performance would be UNCHANGED by the split.

You would need some sort of preference to set just how far before or after the split-point to move things, of course (based on how far on top of the beat you like to play...)

Just to clarify to what you're referring to: can you please post screenshots showing a before-after (split) example.

Here you go. I did some more thinking about this, and concluded that, while notes ever so slightly before the beat should be included in the right item, any notes begun before the split, no matter how long, need to be included in the left item.

I think the correct amount to include notes before the split in the post-splitpoint item is 1/2 of the current quantize value... i.e., if you were to quantize them, they would move to the split point.

Screenshot below....

One more thing:

I think all other control events in the overlap zone could just go in the post-split item. (All bets off with MPE--That would be a much gnarlier script.)

I'm trying to decide if a sus-off (cc#64) should be treated as a note-off... i.e. if the sus pedal is down before the split, should the pedal release event be included in the left item??

Well, it's probably not crucial.... I imagine there are reasons to do it either way.

Thanks for the screenshot and info.

At the moment I'm mainly busy with work. So I don't know yet when I have time to take a closer look at this.
I'll post here as soon as I have any info or updates.
