Super Duper Music Looper XPress
Full user review
"Good for a demonstration only"
Simple controls. Intuitive. Nice pre-recorded instrument sounds.
A bit jerky in the playback. Must pay for any new pre-recorded music. It is unclear what the selection of those would be like. But, it's likely to nickel and dime you to death regardless. Plus, no sign of any ability to make your own track loops.
Too limiting to be useful for anything but making a single demonstration song. Having to purchase individual sounds would make it far too costly to make even a simple selection of music sequences.
