Reactable has released STEPS, an iOS Sequencer that they describe as an easy to use plug & play application that lets you control any MIDI compatible app. This is what they have to say about it...
Send MIDI over the network to your laptop or any other device, and even synchronize external analog synths such as Korg Volcas or Pocket Operators via an audio cable.
Small yet powerful, with STEPS you can create complex rhythmic patterns in surprising new ways.
Forget piano rolls and experiment with Step's inspiring dials.
STEPS comes packed with tons of features and it's Ableton Link compatible, so you can start syncing multiple apps and devices over WiFi straight ahead.
Easy, visual and powerful.
