Oh nice, an iOS music production thread.
I'm using Beatmaker 2 and Multitrack DAW as my two main production apps. And for subtractive synths, I have Sunrizer, iMS-20, NLog Pro, and Magellan. DXi for FM synthesis and Addictive Synth for additive/ wave table synthesis. Oh yeah and Animoog for something completely different. I have more but those are the ones I like the most.
I'm looking to get Thumb Jam for a multi-instrument sound module along with Grain Science, TC-11, and Crystal Synth XT. All in due time though, priorities first.
Utility wise, I have Audiobus and Audio Share (good for working around iOS copy/ paste and sonoma wire works discrepancies). Audiobus is the future. However, Beatmaker 2 doesn't support it yet (it will next update) and Audiobus only supports 3 inputs. So, there is still room for improvement in that area.
For external hardware, I have the iRig Midi which is currently just connected to my controller for now. For those in the market for an ipad mini or ipad 4, the lightning to 30 pin adapter works just fine for 30 pin midi adapters. No idea about the audio adapters though.
I have a couple of questions for you, Lamp. Do you find Cubasis a worthy replacement to Beatmaker 2? Have you run into any bugginess with Cubasis and Auria? I was reading some bad reviews in the app store but for all I know the reviewers were using an ipad 1. I've been skimming through the manuals for both these apps, I just need to find some time to really study and compare everything. Personal input is always helpful though.
