ProLoop is a powerful and flexible loop player for professional musicians as well as hobbyists. Use it as a live electronic
instrument by itself or as an addition to your other gear, or just play around with it and explore the possibilities!
It can play up to 6 loops simultaneously and besides changing the volume each loop can also be pitched/transposed, reversed, muted, panned, ring/frequency/phase-modulated by any other loop, and synchronized to a masterloop.
Pitch can be smoothly adjusted or quantized to a musical unit such as octaves, semitones or a custom division of an octave. Or put it in sync-mode to automagically fit the length of the choosen masterloop.
The sync offset can be adjusted to have loops sync at other positions than their start, and the sync can be turned off individually to allow the loops to have different lengths to create ever-changing layers of soundtextures.
There is also a Freeze FX that lets you temporarily “freeze” a loop with adjustable grain size and position.
You can control all the loops in real-time, and multi-touch will let you adjust several parameters simultaneously, for example crossfading by changing the volume of two loops at the same time.
ProLoop comes bundled with many loops by professional musicians that you can use and play around with, and demo sessions to get you started, but the real power comes by the fact that you can upload your own soundfiles to ProLoop through your web-browser!
The price is $4.99, so not cheap by app store standards, but interesting nonetheless.
