@TheRealZap,
When you have a product that can't be used (properly or fully or whatever you would like to qualify it) without the remote software that is available on IOS only (I mean not even on Windows or OSX), I can't imagine it not to be a deliberate (and hopefully thoroughly though) decision...
Now Line 6 has the right to release some gear that needs an IOS device to work properly if that's what they want even if that sounds crazy to me ... On the other hand, one could criticize them for not clarifying their position on that matter (unless I missed something) ... Is that so difficult to provide some information on their intention ? They can just say we have no intention to develop a "remote editor" for any other OS OR that they may think of it at a later time OR whatever. Honestly, I have difficulties in handling those "corporate" ways of never answering legitimate questions ... It's not like they are asked to provide their "signature" ...
The android audio latency doesn't matter at all for this kind of application ... An Android app can perfectly exchange data over bluetooth... In any cases, as said earlier, it's certainly not a matter of Android because they could have made an app on windows ... if not android.
And as a developer, I can't see any technical reason for not having a cross platform app except maybe for the itune specific stuff ... which they may think is the main selling point - who knows..
That said I don't want to sound like I am angry. I'm just debating ... expressing my views and, of course, would accept to be corrected...
