Regular iOS music makers will be familiar with AppBC as the developer behind Studiomux and Modstep apps. The latter includes some of the Studiomux technology but also offers a fully-blown MIDI sequencer with both step sequencing and piano roll editing environments. If your music making revolves around MIDI, rather than audio recording, then Modstep is a powerful option for sequencing on your iPad.
I did a full review of Modstep just after it was launched and the feature set is impressive. You can use unlimited MIDI tracks and there is support for multiple MIDI continuous controllers on each MIDI track so you can modulate your sound sources to keep your sounds changing, etc. The first significant update added Audio Units (AU) support which was great to see.
It’s only a few weeks since v.1.2 appeared bring some new features and new sample kits. However, AppBC are already back with a further update today. OK, v.1.2.2 is very much of the maintenance variety but it is good to see anyway. This update brings support for those still working under iOS7 (gulp!…. that seems like a long time ago now) and a few minor fixes for known issues.
Modstep is a very powerful MIDI music creation environment with impressive functionality. It is perhaps not for the faint-hearted as that power comes with a depth that does involve an initial learning curve but, as a stand-alone MIDI sequencer, it’s clip-based approach is both very flexible and very creative. The app requires a minimum spec of iOS7, is iPad-only, a 103 MB download and is currently priced at UK£19.99/US$19.99.
