If you have a project file or MIDI file that reproduces this, please let me know.
It's a new standard extension to MIDI for Polyphonic Behavior.
Roli introduced a new keyboard type that lets you glissando between chords (like a pedal steel guitar sliding the metal bar up and down the strings). Several things need to happen to MIDI to simulate this new gesture.
Note starting and end point notes (which are like extensions of pitch bends beyond 2 1/2 steps)
Polyphony considerations (each chord note is assigned to a MIDI Channel)
There are specs available at:
https://midi.org/articles-old/midi-polyphonic-expression-mpe
Many IOS Synths have added support for the extensions.
I suspect your MIDI Tracks support multiple channels in a single "Track" already based upon the behavior of some standard MIDI files I have loaded that play complete orchestra scores with 16
a "score" of instruments at the same time from 1 track. I can see notations like "P25", "P50" in the piano roll with a Colored rectangle and then NOTES are shown in matching colors.
Adding this feature to other DAW's in "non-trivial" but you seem to already have it with multi-channel "instruments" in track. It's just in this case Channels are being used for chord members on the same synth so we can slide (even split apart) chord tones like the "THX Sound" that sweeps into a final chord.
Definitely something you should look into and list on your APP's feature set.
Record/Playback MPE compliant MIDI streams for Moog Model 15, Animoog, Geoshred synths and Roli keyboard inputs.
I'm sure it wold apply on Android as unique as well.
The MPE specification also defines how to handle Pitch Bend, Aftertouch and CC messages to provide maximum interoperability.
I quickly tried the app with Ruismaker and Zeeon, and Zeeon keeps crashing when I tap onto edit button, no more sound nor GUI, and restoring projects don’t restore Zeeon saved preset. Using mainly AU it’s problematic. Also only three inserts effects per track is not enough.
The zoom point is the center between your two fingers. I don't see any other sane way of doing that?
Solved for next release.
Do you notice the lag when using the GeneralUser.sf2 soundfont?
seem to play a role anymore ... i would expect the Piano Roll to be the number of bars i selected initially. Also this initial selection is not visible as range or as markers at all! And finally, even as you cannot see such things, it seems to be a problem when you then add notes outside of the original selection ... This will the displayed, when using "next" again (i would expect an exit button instead for the editor) where it asks if the clip should be extended to the events ... BUT when you are still editing and also playing your notes, those outside the (invisible) range do not play at all. That´s at best confusing, to be honest.
I don't recall having a red range somewhere. The only red background is inside the piano roll, displaying the region outside the currently edited clip. The piano roll editor is entered by either double tapping a clip or after creating a clip. The piano roll will edit the selected clip, it has no relation to a range previously selected.
I just tried Zeeon and it works fine here. Which iPhone do you use? As a temporary solution, you can assign the output of the track to a new bus and add more insert effects there.
Ah, I just purchased a Roli Seaboard block to find and fix a bug, so I should be able to test it.
Thanks!
Yes, it will just record the MIDI events that come in as is. It would be more complicated to force the MIDI channel inside the events to something else.
On iPad Zeeom opens and plays, but the tracks don’t render to audio, the render is blank.
You mean when mixing down? I just had one occasion where after adding the Zeeon AU, recording a MIDI clip and saving a project, then UI turned grey and the AU didn't work anymore. I'll investigate further.
Hi,
If you just purchased a Roli Seaboard (hope you enjoy it!) then I’m sure you’ll want to download the ‘initially free’ Roli Noise app which has lots of MPE enabled patches (lots more for IAP).
You’ll find that if you load it as a AU into AEMS then you get no sound from it. Seems to be a problem with AEMS because running the Roli Noise AU in AUM works fine.
Also, try playing a load of notes and slides and glides into a midi track of AEMS. Seems to work fine at capturing everything correctly on different midi channels (apart from the no-channel pressure bug which you know about).
But then try the ‘split to separate midi tracks’ function. It kind of works, but I think if you look closely at all the resulting midi tracks you’ll find sometimes notes from other midi channels are creeping into the split tracks. Ie it doesn’t always split tracks by event’s midi channels 100% correctly.
It’s fantastic that AEMS is basically an MPE Daw though! Other than GarageBand (which has no access to cc automation at all, not to mention no midi out at all) AEMS is the only DAW on iOS that does this. So it’s a big selling point IMO!
It’s on my iPhone 7 Plus.
I meant rendering the Zeeeon midi instrument track to audio using “Track Options/Render track to audio file”
Ok, well, I'm onto something. Hopefully fixed today.
I solved the issues with Zeeon. I don't think it's really AEM's fault, although I am probably doing something unexpected for the app, but other AU's handle it fine. Fixed for next next release (the next version is already in the queue for more than a day).
In other apps, while you zoom in with two fingers, you can also drag left or right.
In AEM, you can't.
Thanks, you’re fast to fix!! I will test asap all my AU and will let you know if they’re other issues.
Also, I think on iPhone timeline info takes too much space. Do you think it can be improved by diminishing its height or or by displaying only bars or mins via preferences options?
I'm of the opinion that we need "More" information there. tick marks to show grid points, Beats, etc. but if it can be done and made smaller at the same time, I'm ok with that.
I'd definitely like more tick marks though. 
Examples: Pro Tools, Reaper DAW, etc.
More ticks would be great. I keep getting “Not good enough - See me!”...
...
iPhone:
Hit ... More > Grid > Display or Display and snap to grid, then choose your preferred grid size.
iPad: Just hit the Grid button and make your settings.
Don't be afraid of choosing 16ths, the number of grid lines shown adapts intelligently to the current zoom level.
OK, forgive me, but I read this thread early on and decided it didn't apply to me. Now, a gazillion pages later, I'm feeling like I need to catch up. But do I?
• Is this DAW a contender with Cubasis and BM3?
• Is it especially lightweight/nimble/inexpensive?
• Is it a disaster that has infuriated forum members?
• Is it super innovative?
Audio Evolution Mobile Studio 2.0.2 for iOS released:
Yes to one or more of the above...
Hehe, Cubasis had this problem for YEARS but they "fixed" it recently...
But I must admit, while it's only a few divisions, additions and multiplications, just HOW and using WHICH coordinates took me the best part of a day to figure out in Xequence as well!
I used the Grid Display religiously.
But, visual information such as tick marks is incredibly helpful for me. :-)
Well, I never felt the need because grid snapping is available but indeed they could be drawn in a suitable color behind the white numbers on the time/beat scale. Is that what you mean?
Absolutely! It is very similar to Auria.
It is not only lightweight, but very inexpensive. Also, it is the only DAW in its class that supports iPhones.
Not that I've heard of.
Not necessarily innovative. Everything it has has existed before. The key phrase would be: Very well laid out. Or possibly: Very easy to get work done in.
That would work. Have you seen MultiTrack DAW timeline tick marks? They show up whether zoomed in or zoomed out. It helps me see better where things go. Also, I'd love to see a better contrast with the grid lines. Sometimes it looks like it is almost black on black or black on very dark grey. These are feature requests @dwrae

Thank you.
So to simply glide over ten pages of comments, this seems valuable to someone who isn't already invested in a DAW or as a DAW for iPhone use?
@dwrae
In the piano roll, the dynamic note length is no more independent from the grid setting.
Notes should rather be created with their length imposed by the currently visible grid width.
