Modstep is live performance gold!!!

Modstep is such a great sequencer! It has by far the most functionality of any music production apps for iOS, but it does have a steep learning curve and a few quirks. While it’s definitely daunting for amateurs, it has just about everything a pro could want for live production and performance including extensive MIDI control and mapping.

A few minor tweaks that would make a lot of the Modstep community very happy are: 1) A MIDI CC option to launch the next/previous scene, instead of having to map each scene to a control. 2) A dedicated “undo” button since it’s very disruptive to workflow to have to load from the auto-saves. 3) Metronome volume adjustment and panning. 4) The ability to mute MIDI notes (not just channel audio) so that instrument loops can be brought in and out of the mix, in-time, and with effects (reverb tails, etc.). 5) Support for AU MIDI plug-ins... and though this is one of the most “mappable” MIDI apps out there, the ability to map even more stuff is always great. ;) Thoughts from the devs?

Just another EPIC but abandoned app. by these great devs!?!

This app has SO much potential but yet again we are all left only wishing these dev.’s would continue to show love towards their apps. & their fans/users who purchase them, but it feels to me like a dreadfully sad pattern that they just put out a seemingly epic app every now and again only to be rejected & leave their loyal buyers feeling rejected as well!?! Why??? Only to make a few initial bucks and then bail on us again??? Bummer...

I always start out loving their wonderful creations but then, like many others they seem to fade out of the workflow. It seems like the devs could care less about your music making experience, your feedback, or iOS music making in general when they just end up neglecting their users and even their own phenomenal creations..

No MIDI import

I got this app so I could import my MIDI files into it for use with other apps. The developers are short sighted and overlooked this basic function. So then I discovered I could export MIDI from another app into it. However, when Modstep receives the MIDI clips, it changes the note data. Considering that everything I’ve bought from these developers does not work, it’s best to steer clear of them and everything they make. Not to mention, that neither Apple or the developer will refund my purchase. I lost $20 on a broken app, which looks like it will never get fixed.
