What's New

Version 3.0

• All MIDI Instruments (except for IAA) now have an option to specify note names. These names appear in the drum editor.
• Articulations for multitimbral External MIDI Instruments and AUi plugins. You can use a MIDI controller to switch between bowed and pizzicato violin, for example.
• Cycling transport: transport bar now has Cycle button.
• 12.9 inch iPad: tracks have Content Panes showing a compact version of the data in the track editor.
• Swipe left over start/stop button to rewind. Also stops transport if it's running.
• SoundFont Player: you can load next/previous soundfont by swiping vertically over SoundFont box (just like you can with the Preset box).
• SoundFont Player: the SoundFont box list now automatically scrolls to the currently loaded soundfont.
• Note Editor pane: you can now type semitone offset in Note box (for example: if it's C5 and you type -2 it becomes Bb4).
• MultitrackStudio Instruments synths: attack is now linear rather than exponential, in order to avoid the synths being noticeably 'late'.

• Level meters no longer have 'LED' segments.
• Editor graphics are more CPU efficient.
• Fixed: Running an audio track in practice mode no longer clears the track editor undo history.

Ratings and Reviews

Another update for the top of the class


The very brilliance of this app explains the poor reviews: it's idiosyncratic, and there's a learning curve. The developer is incredibly responsive, and a relentless updater, and his application does more with midi and audio editors (and more elegantly) than any other iOS DAW.

Great for a performing MidI musician


I have a one person stage show with two keyboards, a drum machine sampler and a rack full of synths. I perform live with MIDI tracks I create, and don't have the luxury of a roadie or sound tech to help with things like the light show and video show and all. After I create a song, I play the exported MIDI files on stage using another popular "player" app. That said, I have to say that I am super excited to have this app which writes bank select, program changes, volume, pan and all the other CC messages to the exported MIDI file. I have looked at all the iPad DAWs and this is the only one that can do this. Being a one person show, it is critical that at the beginning of each song the MIDI file sets up all my synths- I don't have time to manually fiddle with controller knobs and sliders or even remember their settings. Desktop software and hardware sequencers have long been able to write this data into the file output, but if you, like me, are wanting to work primarily with the iPad then this is it. Support from the developer is good and prompt. I would say this app is worth the price and I am glad to have purchased.

Very Satisfied


I just got MTS a few days ago and have been comparing it to Cubasis, GarageBand and etc. I have to say that I like MTS more than any other iOS MIDI sequencer and feel that I have finally found an iOS sequencer that does everything I need in the most straightforward way. MTS lets me record MIDI with poly aftertouch from my USB keyboard and apply it to other iPad synth apps.

Because of its versatility and ease of use, I've become very comfortable with it in a short period of time. Once you figure out the "hidden" features it's quick and easy to get around.
