I have personally written a message to respected developer Michael. Supposing that he may not respond to all messages from all around the world, I would like to put the issue on the table too. I am open to any working ideas...
I own an iPad 4th generation. iOs 7.0.3, a Roland Duo Capture Ex audio/midi interface, Icon G-Board USB foot controller, a powered USB Hub to be able to make Icon work and LOOPY HD! When I turn on all the staff, rig is ready. I connected Roland's MIDI IN to my desktop computer's sound card's MIDI OUT to get the clock from Ableton Live. When I play Ableton session, Loopy HD is on the go. Controlling loops with my Icon is no prob. However, I get some issues during real time play and record:
Although I set count in to 1 bar and press record switch within the LAST bar (familiar process as in Ableton's quantized recording system), Loopy does not always start recording on upcoming 1st beat as it is expected. So it counts one more bar and starts recording. This is real problem when you are not just freely looping and have a traffic to follow on back ground :( I also tried count-in as clock time by setting it to 1 on loopy. No consistency. I am still working on it before putting it on stage.
The 1 bar counting problem also occurs when I try to end the recording. (I expect it to be just as in Ableton Live's quantized loop recording. Namely, I press the toggle record switch DURING the LAST bar of my recording, but Loopy may not be able to end recording and play back, instead it continues to record and ads one more bar to my loop where everything goes out of order as you may guess.
Last problem is: Although everything goes quantized, Loopy sometimes eats the beginning of the recorded loop just after it quits recording and passes onto play back. Is it a common failure, I do not know. but I encountered it many times.
What may be the reason of all these problems? Is it a MIDI clock issue? Is Loopy HD not ready yet to get massive stabile timing with external master clock?
P.S. I also checked it WITHOUT receiving MIDI clock from external hardware (Ableton). Neither of the problems above occur. :( That is bad news because my first aim by purchasing iPad installed with Loopy HD was to use it on stage synchronized (as a Slave) with other hardware such as Ableton running computer or another clock sending synth. I think the developer of this wonderful program should work around this issue more.
Best Regards
