Setting Reaper recorded MIDI base to Time is still affected by tempo, changing Source Properties to ignore project tempo doesn't seem work correctly either.

I recorded from my MIDI keyboard directly into Reaper. In the past I've set MIDI items to Time base and then used tap tempo, the MIDI is now still affected by changing tempo despite being set to time.

In the past I've used the time base this way and it worked but now no matter what the MIDI base is it changes with tempo.

I also tried going into the Source settings and selecting 'ignore project tempo'. The problem with this is that as soon as I turn that off the MIDI stretches with the project tempo again, even when its base is time!

I want the MIDI to temporarily change tempo so I can quantize. Then I want it to follow the project tempo so I can automate tempo changes. Using 'detect tempo' does not come close to the correct tempo in this case so I can't use that.

Not sure if this belongs here or in a separate thread - but the action - 'SWS/FNG: Quantize item positions and MIDI note positions to grid' is not quantizing midi notes correctly when swing grid is enabled.

Since it's about functionality provided by SWS extension it's best reported on the SWS issue tracker.

DUCKETT · 11-24-2019, 09:30 AM

Looked at the list of bugs, didn't find this particular issue:
intermittency of successful MIDI signal propagation to new instrument channel.

Just to get this out of the way: REAPER is 5.9.8.2, system is Win 7 (x64) SP1 Home, MIDI controller is an Axiom 61, audio interface is a Saffire Pro 14.

Sometimes, it's a particular VSTi; the track shows the little red line indicating MIDI signal, but the VSTi sometimes won't "wake up" until pressing a key on its virtual keyboard (if it has one), which for whatever obscure reason works.

Other times, there's not even the MIDI indicator signal; if a VSTi has a keyboard or sequencer, those will work- but no amount of resetting all MIDI devices, unplugging/replugging the Axiom's USB connector and refreshing, closing/re-opening the project, or deleting the track and creating a new one, is likely to work.

I've also made sure REAPER's got plenty of memory and HD space to work with, so that's not a factor.

I've tried also switching the MIDI driver from the Axiom to MIDI4ALL, the Saffire MIDI, and even tried LoopBe to see if it would help.

What's got me posting is not that it's a constant issue, but one that's impossible (for me, at least) to predict or pin down and eliminate.

If the very fine folks at Cockos really want to guarantee more converts to REAPER, they might consider designating a larger chunk of time and energy to making this thread a dusty, forgotten relic. It's not NEARly as horrific, but MIDI-as-afterthought was the issue that frustrated me the most with (and drove me away from) ACID, and what I tried to replace ACID with, Sonar X1. Perhaps bad-MIDI-PTSD is coloring my thinking

Joe90 · 12-14-2019, 09:22 AM

Hi,

Any of you Reaper midi veterans know how to deal with this -

More info here - https://forum.cockos.com/showthread.php?t=228591

This is causing me major headaches, and I'm just wondering how other midi users are dealing with it.

Midi notes doubling in overdub mode after deleting notes when recording.
This has been pointed out several times and is a real reAL REAL P.I.T.A
Sorry to be the same lol
I know the dev's are working on take markers and other awesome features etc but this problem really needs to be addressed it's been happening after v5.99 and also seems to be after the new touch latch replace modes were introduced which was a brilliant idea except it doesn't seem to work ?

Can we have it back to how it was before the new modes and at least have a working system without having to sacrafice all the great new features in v6.

I am surely not the only one who finds this frustrating? please tell me if I am lol. It sounds like the midi notes are stuck in a buffer somewhere..

Many thanks

Logutin · 04-11-2020, 02:26 PM

In https://www.reaper.fm/whatsnew.txt of v6.08 we find: “+ MIDI: prevent double event playback in certain overdub situations”, but I have very similar problem:
When recording MIDI in overdub mode using input quantize, notes are doubling if there are already quantized notes on a track.
To reproduce:
1. Record some midi with input quantize in overdub mode – work as intended.
2. Record more midi in the same place in the project – notes will be doubling.

barbaroja · 04-21-2020, 02:46 AM

The midi editor is not remembering the scale.

I guess the right behavior would be to remember the scale, and if the midi clip is new, then use the scale in the last clip (as different clips may have different scales)

looks like some bugs quietly got squashed, like this one:

https://forum.cockos.com/showthread....33#post2282733

edit, WEIRD. i was able to get the correct behavior for a minute (all notes should nudge) but now it's back to only the "Active" midi item. this is so bizarre, i downgraded to see if this was new behavior and when i upgraded back to the current pre, i could no longer use the mousewheel to nudge all selected notes on all editable midi.

(This has been already reported in the general Bugs Subforum. A minimal project exposing the bug is provided there. Quoting here for ease of reference/completeness.)

I am attaching a minimal project that shows this behavior.

Still having problems with the first note in a MIDI item failing to play when playback starts flush from the left edge of the item. Starting playback just a few ms ahead ensures the first note plays.

It doesn't always happen. I am not able to pinpoint the circumstances that trigger the bug, but it's frequent enough to be annoying.

ovnis · 11-04-2020, 05:43 AM

Lack of consistency.

When I select two or more items, I can mute all of them at one time.

But I can't do the same thing with midi notes!

juliansader · 11-04-2020, 07:43 AM

Strange, muting is supposed to work on all selected notes. Which action are you using? Could you perhaps upload a minimal RPP?

NB: It is better to report bugs in a separate thread. This thread is just a reference list (that I haven't updated in quite some time).

Joe90 · 02-13-2022, 09:05 PM

When 'correct overlapping notes' is on, copying/duplicating notes over existing muted midi notes will cause Reaper to keep the muted midi note and remove the unmuted note you are trying to paste there.

The ideal behaviour would be the existing muted notes are removed, rather than the unmuted notes that are actively being put there.

I'm very much hoping this can be fixed at some point as it causes me issues on an almost daily basis.

edit: just realised the start of my gif has been cut off, but it starts with my duplicating that block of midi notes over, and then shows the muted notes taking precedence over the notes I'm trying to duplicate.

Reid115 · 03-10-2022, 03:51 PM

Has anyone noticed that the responsiveness of MIDI is laggy in certain contexts? For example, if MIDI is playing in the arrangement and you mute the track, there will be several moments where new MIDI notes will still be triggered until it finally stops:

I've also noticed it takes a short moment before instruments respond to MIDI right after turning on the record arm button:

LarrySeyer · 08-23-2022, 09:38 AM

I think I may have found another one.

Not sure if this has been mentioned earlier in this thread.

LarrySeyer · 08-27-2022, 10:18 AM

Create a track
Arm that track for MIDI recording
Record one sustained MIDI note on it for 1 measure
Unarm that track
Create a 2nd track
Arm that track
transport play
after first track plays its midi note but before it finishes hit transport record.

It CUTS OFF the unarmed track!!!!

Frustrating!!!!

de3ds · 10-02-2022, 09:55 AM

It feels as though MIDI was an afterthought, and not been given anything like any more thought since then.

Just scrolling the timeline of MIDI is bizarre, let alone the myriad of issues that permeate actually using it.

audiotect · 10-30-2022, 12:17 PM

Hi
Seems like midi is a little weak in Reaper..
well I had and have my issues
one is quite irritating:
When in midi editor playing and then stopping playback
the sound makes a very short agressive loop.
I only goes away when i point the curser someplace else or start playback again

I could be what people call stuck notes
but I can´t figure that out
It doesn´t happen when playing back midi from the arrangement window

Fix?

Hi,

first, i want to apologige if my english is bad!!!

I want to report here a bug when i copy/paste a midi item more than 3/ 4 times......even if this item is on the grid with the snap enabled, ther's a shift after 3 or 4 copy/paste.

And then i have to put it on the the grid manually.........and i nearly use midi instruments in my music productions.

This bug was already here in earlier versions, was fixed, and reappared since 4 update (aprroximatively).

Is it possible to report it to the devs to fix it......as sooner as possible?

Thanks everyone!

AlexAndr · 11-17-2022, 03:11 PM

Tell me why in the ripper it can be so that the font does not fit into the settings window? ReaperReaders_x64.dll - not installed, if anything.

ARkaine2 · 11-17-2022, 05:45 PM

It's possible to do a lot of actions in multiple MIDI items, even split notes in different MIDI items, but it's not possible to join ("glue") selected notes in different MIDI items.

I think that it's not logical way of action and probably even bug.

Example of what I'm talking about is in screenshot.

I'll be wait fix of that. Thanks.

sproost · 11-18-2022, 09:00 AM

Editing a single note velocity seems to trigger the velocity of adjacent notes.

It's finnicky to have to hit the very narrow velocity line exactly, and also this behavior makes it very difficult to draw curves and ramps (like how it behaves with CC). I think this certainly isn't the way it should be?

I think the option in Preferences->MIDI Editor "Prevent mouse edits of single CC events from moving past other events" should be enabled.
But firstly try this option: MIDI Editor Options->CC/velocity lane->Edit CC/velocity only when mouse is near event.

Fantastic, the 2nd option fixed it. This has been bugging me for years, but it was never important enough to figure out how to fix it. So thanks a ton!
