"a looper unlike any other.. you would be damn wrong not to test it.." - Guitar Part Magazine June 2014 (biggest french guitar magazine) Loopr is the first 64 tracks loop song sequencer / multiple phrase looper with MIDI controls and sync for real time live composition. A musical instrument like no other. "Loopr is a budget-priced bargain that is well worth a punt even if only to experiment with. This is a very capable – if slightly quirky – looper app at a pocket money price." musicappblog.com November 2013 Honorable mention as finalist in the Best App Ever Awards 2013 ( http://www.bestappever.com/awards/2013/winner/musc ) Loopr is a low latency loop recorder, player and step sequencer designed for realtime phrase and song composition using your iDevice. Compose, practice, jam along, or sample audio soudscapes easily with this compact pro-oriented loopstation. It is focused on ergonomy and simplicity via one-finger but also hands-free MIDI pedalboard controls, and lets you synchronize drum machines and sequencers via its MIDI out sync. Loop sessions can be exported/imported as independent files (including tempo and time signature information), for you to share the groove or use with most desktop audio production apps (e.g. Logic Studio, Garage Band, ...). Using iTunes file sharing or email, you can easily manage your work beyond your iPhone or iPod Touch. Loopr is CoreMIDI and CoreAudio compatible and enables you to use most popular iOS compatible interfaces.
