Breeder made some nice updates - thanks!:

CHANGELOG:

11.9.2014 (by Breeder):

• support for 14bit lanes, pitch, aftertouch and program lanes (anything that's drawable)
• when in CC mode, user is still able to edit velocity by clicking it's lane
• ctrl+click target fader sets it to the middle
• preserve settings through REAPER or script restarts(mode, compressor weight and target, dialog dimensions)

[Viente]

Thanks!

[adaragray]

i was waiting for this thank you so much spk77

[beingmf]

wow - game changing!!! any chance to get an undo-compatible version soon??

[spk77]

Thanks. I couldn't get the "undo" working correctly - have to do more testing.

[gofer]

YAY! Congrats

There definitely needs to be such a thing for CC as well (probably on last clicked lane?? Wouldn't make too much sense to use all selected in different lanes).


Hopefully this doesn't take away from the devs drive to implement a transform frame thingie for CC, velocity and possibly automation envelope lanes.

[spk77]

Undo should work now - zip file updated. (had to use Undo_OnStateChange("descchange") to get it working)

[spk77]

Thanks gofer (maybe this will give some ideas to the devs. )

Zip file updated (in post#1):

• ctrl+drag to "apply exponential velocity curve"

[Anton9]

Man.., this along with your MIDI note selector running at the same time is quite the power combo. I really like the exponential adjustment too. Awesome job!!!

A couple of ideas for the velocity tool:

1)Perhaps a parameter that could be either click-dragged or mousewhell scrolled that would set all the selected velocities to the same value.

2)A button that could transpose/flip the edited velocities from left-right or right-left.

3)Maybe a reset button that would set velocities back to their pre-edited values.

[Ozymandias]

Great work, Spk77!

I really hope this gets incorporated into the MIDI Editor at some point. That would make REAPER's velocity handling on a par with Cubase's.

Thanks Anton ,

1) I've been thinking (how) to make a "smoothness control node" - it would move velocities towards the curve by 0-100 percent. Then another "node" which would adjust "smoothness/compress strength by note position".

2) That's possible to do, but I think it should flip the velocities "per channel" and "per pitch". Then it would work correctly, even when selected notes have different channels/pitches. Possible but not very easy .

3) Original velocities are deleted from memory when lmb is released, but undo should set velocities back to original.

Thanks, I'm sure they'll add the same behavior/logic to the MIDI editor at some point. Let's hope.

Update - "alt+drag" -> set curve and compress

A fast way to add fade-ins/fade-outs:

[Seventh]

Very cool but uh... how do I install it?

EDIT: Figured out that I need to load it up in the actions list. For some reason the New/Load button does nothing though... even though it works on a fresh install.

EDIT: Figured out the problem too. The "lastscript=" path in reaper.ini was a remnant from my laptop. Since that directory doesn't exist, the load window refused to open.

Unzip the file -> open the "Action list" -> load the file (ReaScript New/load...)
Then it should be in the action list (as an action).

[Seventh]

Ok got it working. Thanks for the script!

By the way, would it be possible to make it do compression/expansion of velocities (without ramp)? :P

Cheers!

Glad you got it working . Compress/expand -tool has been on my mind too.

[spk77]

Compress/expand velocities (compresses towards average velocity)

That's going to be very useful. Thanks!

[adaragray]

indeed very useful. thank you spk77

[Anton9]

Nice updates

[Seventh]

Wohoo thanks!

Now, imagine how cool it would be if you could permanently dock this in the MIDI editor screenset... along with other scripted tools with interfaces... maybe something for Reaper v5.

Oh and, can the script listen to keyboard input? I'd really like to be able to close the window with esc key after using. And it would be ideal for it to pass keyboard commands like Ctrl+z through to Reaper.

Cheers

[heda]

Great! Thank you very much!

I was testing it on a bigger project with a piano track with many many notes and, even if I selected only a few to modify with the script, I could hear a lot of cracking sounds when dragging the control if it is playing the track. Not a big deal. But maybe it can be optimized to run in lower priority or something? Maybe it is just the way EEL scripts work.

How can I have the script window on top of the midi editor window? When I go and select other notes, the window disappears behind the midi editor window. It needs the little pin button

[spk77]

Thank you all,

In the next update, ctrl+z will be "undo" and esc-key will be "exit script".

Hmm..this script will take "relatively lot" of cpu resources when there are a lot of selected notes, don't know how to optimize it.

It's not possible, unfortunately. Maybe it will be possible in the future (if/when EEL is updated) .

Hi,

thank you very much spk77..a really usefull tool! You are very skilled and generous..thanks!
I use a docked midi editor and the scripts gui does stay on top.

Awesome ^_^

[FnA]

Thanks, spk77. I'm sure it will get much usage.

[cyrilfb]

This will improve my workflow tremendously. I am terrible at drawing the changes with a mouse.

Thanks

[spk77]

Thanks again

I'm probably updating it this weekend (checking if there are serious bugs).

Here's another idea - "Pitch bend tool" (diving deep into the horrors of decaying sine um..curves).
(adjusting velocities in this gif)


I'm running out of axis:
1) lmb down+move mouse in y-coord: set wave height
2) lmb down+move mouse in x-coord: set decay
3) lmb down+move mouse in z-coord (towards floor/roof): do something
4) ? keeping lmb firmly down while pushing mouse through time: set wave length (number of sine waves)

Excellent stuff, spk77!

While I think some tools to aid pitch bend editing would be awesome, the idea of varying sine curves doesn't interest me much. Instead, I'd suggest to focus on ways to vary the shape of a (single) curve.

Consider that most targets for pitch bend (typically, synths) can already achieve tremolo/vibrato effects simply by using a (synced) LFO modulating oscillator pitch, where one simply has to draw a ramp of modulation values to indicate the depth of the sine waves. For that (typical) case, it is quite a convoluted workflow. Also, while it may be attractive to see the curve shape 'exactly' on screen, for a variety of reasons the result of modulation by an internal LFO typically produces much smoother results. (Of course, on the other hand, this would very useful when this approach is not possible.)

Btw, while pitch bend data is 14 bits, most targets respond only to a lower (e.g. 8 bit) resolution. You may want to account for that by doing some 'magic' during processing, so one may avoid having redundant MIDI data.

[Anton9]

spk77,

I would absolutely love to see something like the decaying sine curve for sending OSC messages to FX parameters. Do you know if it would be possible to do something like that and have the sine function plotted in an eel gfx window?

Yeah, I'm just experimenting what's possible with EEL. (and I'm still using the MS wavetable synth ).

I think it's possible, but I don't know how accurate (time wise) it would be.

Hi Spk77!

Above all, thank you very, very, very, much for this great tool!! It was one of the few things I really missed in Reaper´s midi toolbox. In the image of your first post you seem to apply the tool, besides the velocities, to a bunch of CCs, but I must be wrong since it seems to work only for velocities. Have you thought, as another poster asked, to do a CC version of it? I see you are planning a pitch version, so if you could complete the set with a CC version, it would be absolutely killer for all of us midi users! Excuse me if I ended up asking for something besides giving you thanks, but I couldn´t resist the temptation...

What you did is really helpful...

Hi,
Yes, I'm adjusting velocities in the first post. I'll try to make a CC version also - I think I just convert this "velocity version" to work with selected CC events (for now).

Awesome! -fantastic! - incredible!...(and the list goes on).

Thanks so much in advance!

[spk77]

zip file (post#1) is updated: "Apply curves to CCs":

NOTE: This doesn't work correctly (yet) when CCs from different lanes are selected. (curve is applied to all selected cc events). Also, not tested much.



Edit: range == 1 to 127 in "Velocity" mode and 0 to 127 in "CC" mode.

[FnA]

spk77, do you think it could be applied to position and length? Accel/decell and staccato/legato?

[spk77]

Yes, I think. At least it's possible to change pos/length with MIDI_SetNote().
