Just in case you were wondering what version iPad was in that amazing Audiobus demo, it was an iPad 2. It seemed to be handling Sunrizer and Loopy just fine, which is good news for iPad 2 owners, and even better news for iPad 3 owners. I shot Michael an email asking how if he could put a number on how many apps working together at the same time start to slow things down, he replied:
What we’ve found is it depends enormously on the apps in question. For example, Sunrizer is quite CPU intensive when used with certain patches, and things start to get a bit soupy when that’s used with two other apps, like Multitrack DAW and SoundPrism, for example.
When you get down to it, this has little to do with Audiobus, and everything to do with the apps in question. Audiobus doesn’t add a very significant footprint to the apps, so – if those apps work together before Audiobus, they’ll work together after Audiobus. If not.. they won’t =)
