@Travst:
I bought my iPad especially to be my all-in-one controller instead of investing in several hardware ones. Luckily I ran into this MIDI Designer app which is so fast and easy to work with, both when designing and just using it. I've tried out some others, but they either required a PC to design on, or were just too cumbersome to get the stuff going that I wanted to create.
Since I have the iPad - and my layouts for the Rolands ofcourse :-) - I haven't used my BCR at all anymore, except as a MIDI interface for my iPad :D
Mind you that you will have to have some kind of MIDI interface for your iPad if you purely work with hardware (ie no computer). The BCR2000 works fine in combination with the Camera Connection Kit's (CCK). If you use a computer as your sequencer, a Mac natively supports the "MIDI over Wifi" thing that the iPad (and iPhone) does, and for a Windows PC you'll need Tobias Erichsen's rtpMIDI, which is free. That is obviously the nicest way to use your iPad - you can just sit on your (studio) couch or anywhere else and program your synths! :-)
The greatest thing that hit the iPad/iPhone music scene recently is "AudioBus", an app that enables compatible apps to send their audio to another (compatible) app. Thus you can run a drumcomputer (like the great DM-1) in the background, and record it in your sequencer app, which sends MIDI sync to the DM-1. Marvellous stuff!
@Bitley:
Indeed :-) As I don't have an Alpha Juno/MKS-50 myself, I hadn't been able to test the layout yet, but a very enthusiastic fellow user is testing it as we speak. It actually seems that the Alpha Juno has *exactly* the same Sysex implementation as the MKS-50, so there's no need for the two separate pages that I made. I'll update it real soon when I get the testresults in, and post an update!
@Dougt/Forwerd:
I might do an MKS-80 page some day when I find the time, although I haven't got one. I've studied the Sysex implementation a bit, and know beforehand that some controls will behave awkward, as the MKS-80 has some parameters that are stashed in the same Byte, so altering one control will suddenly send the values for something else too. This is caused by the Roland programmers in the 80s, who wanted a patch to take up as little memory as possible... the MPG-80 should do exactly the same though, but I don't have experience with it.
Thanks for all the positive responses!
