Midi File Editors
Is there a good app for showing what is going on in a .mid file, aside from the various piano roll editors? I exported a file from one app, imported it into another app, and there was a spurious 120 bps marker at the beginning of it. I'd like to be able to look at the contents for additional troubleshooting. There were a few other issues in it as well. This may be the old programmer in me thinking that this is a good idea. I was always under the impression that midi was a textual file format - but I tried to open the file in textastic, and it indicated that it was a binary file.
Any suggestions?

I know @midiSequencer was working on just such an app.
You could try some of the notation apps like reflow 2 if you're comfortable with reading sheet music. I'm not sure which one would be the best, though.
I just randomly download .mid file from a website. Straight 'open in' into MTS. it did a automatically arrangement tracks. Then open any tracks window, I was able to edit any midi notes. MTS is very reliable for doing this things. You can then rearrange notes quantize, swing, transpose...etc, much more

I'm not aware of editors for messgaes other than Note or CC, but you can use tools like MidiWrench to watch the midi stream to see other messages (tempo change, Program change, SYSEX etc...), or tools like MidiFlow or MidiBridge to filter them out while recording the midi into a something else ?
I use MTS, like @Kaikoo described above. One of the reasons it works so well is that it not only has the ability to interpret MIDI data and separate into tracks, but then also has the editing capabilities to work with it and on-board instruments (signaled by a 0-127 code in the MIDI data) to set up that track properly. You can literally import the file and just press "play" and be amazed how close it sounds to the actual song, albeit with more primitive versions of each instrument. Great as a backing track, or as a compositional starting point.
Does MTS also have a notation view?
Yes, but I am illiterate. What you see is just from midi notes.
Thanks, so that doesn't seem to be very useful unfortunately. If it had a good notation view I would be more tempted to buy MTS.
You can point to the notation, it has the sound from that notes on your instrument. You can zoom in and out. It's your choice!
I see. It just looks so bad, though. But of course it's more of a side feature and not the main focus of MTS. It definitely could use some improvements anyways.
I built the file in Notion. My issue is trying to diagnose stuff that shouldn't be there. At it's heart, midi is a I believe just XML, which is text. Midiwrench might work for me. Most of the midi "editors" are great if everything is fine. Which, most of the time they should be, I guess.
It is reliable, man! MTS is not to joking you. It's developer constantly solve what you need for. And what get wrong with it in speedy super programing way! If you are the owner, you knew what I am talking about.
Midi files are binary files, you can view the contents with a hex editor, but not a plain text editor, MIDI files were around long before XML was defined
Ah, then I have been mistaken. Tx.
Cakewalk on the desktop a couple of decades ago had a utility where you could enter midi in text form, note,duration,velocity and one maybe two other parameters. My drummer roommate athe time preferred that method to the piano roll style.
Think you're looking for an app with MIDI Event List but I can't think of a single one on iOS. It's another one of those features MIDI editors have had on the desktop since DOS/Amiga. They're handy!
Surely some app has one. Does SunVox import MIDI? It's basically a big old event list.
That a> @syrupcore said:
I think that's exactly what I'm looking for. It's a starting point, at any rate.
Yes, sunvox does import MIDI but I don't understand it enough to know if there is an actual tempo event anywhere.
Midi Tool Box. There we go.
Do you mean this one?
Midi Tool Box by ART Teknika.

I've looked at that app before because it appears to do several useful things but not purchased. Would be interested to know how useful the tools are. I see it has a monitor and a midi file player but didn't see an event list in the feature list.
Bought it, and then asked for a refund. It seems to be set up to sit in the middle of a flow, while I wanted to open a file in it. They have a player in it, and a file manager, so not sure why it wouldn't do that, seems like a not unintelligent use. Graphics were primitive, it only works in portrait mode. And when I went to check the documentation to see if I could make it work the way I wanted to, it was all in I believe Japanese.
Midi monitor pro also does event lists, but also looks like it only handles a flow, won't run a midi file.
An iOS app with a midi event editor and the ability to export separate midi files for each channel/track would be great!
Indeed. Filter and export would be great. Along with event editing.
If I edit the velocity (deside that A4 note) , you can see the circle for the the note being chosen.
Also, see and tick each of the midi tracks you would like to export. I will not talk more on this discussion, it's up to you to decide what app is better than MTS?
iOS is still waiting for this it appears.
Was hoping that Xequence would fit the bill but it sounds like Midi File import is, unfortunately, way down on their to-do list.
The MIDI Scope by Kinematic Systems app does a good job of listing MIDI events it listens to or that are sent to it.
Haven't tried it but I believe there are few online, https://solmire.com/midieditor/
Midi Scope allows midi file import now?
