Default Adjust time to fit MIDI: Piano Roll

Is there a way to stretch/squish the underlying timelines of a MIDI Piano Roll to better fit the recorded notes?

I don't want the rate or playback qualities of the recorded MIDI notes to change, at all, simply to fit the timelines to it.

It is WAY off. The recording was made without any references to time, a click or other form of metronomic consideration.

First, you must ensure that the MIDI doesn't follow the timeline while you are editing it. Set the MIDI item's timebase to time, and set the MIDI inside to "Ignore project tempo". (Use the SWS action [[SWS/BR: Enable "Ignore project tempo" for selected MIDI items preserving time position]].)

Then, you can adjust the tempo to nicely fit the MIDI, using standard tempo mapping functions.

* Check out Youtube videos on tempo mapping, particularly Kenny Goia / REAPER Mania's ones (the most recent ones, since REAPER added several new tempo functions in recent versions),

* Also check out the amazing tempo mapping features that Breeder coded for SWS, which Kenny unfortunately does not cover: Tempo mapping and manipulation with SWS.

Afterwards, change the MIDI items' timebase back to beats, and disable "Ignore project tempo", while preserving positions, using the SWS action.

Apologies. I'm new to Reaper, and much of this is too dense for me.

What is SWS and what is an SWS Action?

What's a BR?

There are two essential extensions that every REAPER user should install:
* SWS, as dangguidan linked to above, and
* ReaPack, which allows you to easily discover and install ReaScripts, JS effects, extensions, themes, etc.

"BR" refers to Breeder, a user who coded some phenomenal features for SWS, including various tempo-mapping functions. The names of most user-coded actions and scripts start with the user's initials.

BTW, Kenny Gioia has just released a new series of Youtube videos for REAPER 6, which will be very helpful for new users. As far as I can tell, the series does not yet cover the SWS extension and other user-coded features, but you can easily find more information about those on the forum.

Thank you very much for these introductions to "ESSENTIALS".

Have been battling with Reaper, heavily.

Using a Yamaha MODX with it. And just about everything is infuriating.

Slightly less so than the alternatives (Cubase, Cakewalk, Logic etc).

The MODX is a 16 channels-at-once monster MIDI thing. Great in theory, horribly riddled with problems in reality, even only trying to use a few of those channels begin building a performance, things go awry really fast.

Hung notes, hanging sustains, runaway changes to the "SuperKnob" and other disasters mean nothing productive has yet occurred.

Still trying to find a setup that permits composition and experimentation.

So far only recording works somewhat consistently, so at least ideas aren't getting lost.
