  1. I dl’d the first version of this; was underwhelmed by the fact that it failed to recognize the Alesis ioDock. Underwhelmed by the FX options, but I’ll overlook that since it’s really about having the synth engine.

    Have since updated to the current version and will give it a try to see just how much it’s been improved.

    Still skeptical … 13-pin is going to be hard to beat.

  2. Was seriously disappointed with the iPad version. Tried so many settings to get it to work with my guitar but the tracking was just hideous.

    I really wanted this to be good, but it just fails.

  3. Nicely done. I am pleasantly freaked by the means to have the only remaining problem be powering adequate speakers. Someone will probably come along with something electrostatic that you can roll out and hang from a coat hook:P. We’re closer than ever to the day when a solo musician can carry everything s/he needs by themselves and not break a sweat. This path is still new and a bit glitchy, but with things like the Animoog appearing, its sci-fi, baby. Now where the heck is my flying car?
