Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
Looking for specific sequencer (like Moog Sub37)
There has been a thread on sequencer recommendations by @ThinAirX recently, but rather than 'hijacking' that thread I thought I'd rather come up with a new one.
I am looking for a sequencer that can work as brain/node/hub for my Sub37, Model D and Rev2 and works as a jack of all trades (what we in German call the 'eierlegende Wollmichsau'). The Sub 37 has the best ARP/Sequencer unit I know, so I'm probably looking for an app that can do the same but control more than one sequence at the same time.
What I'm looking for should be able to do the following things:
- Receive and record note input from external synths. In my dream, it has some sort of 'listening' function like Ableton Live's capture mode which can recall midi entries even though no 'record' button had been pressed (I think that's a market niche on IOS, imagine some midi app that constantly functions as a sort of midi input clipboard in AUM).
- Being able to see and edit the recorded notes (this is where Rozeta Cells fails for me, even though I like its simplicity).
- Ability to see at least 32 steps at the same time (like Xynthesizr; or as a piano roll, Drambo is less intuitive in this regard).
- Ability to record different sequences which I'd like to send to different synths at the same time, and, if possible, in the same key.
- Ability to choose scales, possibility of quantisation.
The next two points are extremely important to me:
- Ability to globally transpose entire sequences on different tracks (i.e. different Midi channels) at the same time (like Fugue Machine BUT) by pressing a single note on a Midi keyboard.
- This last point is the one that has bugged me for quite some time, and it has to do with the centre transposition pitch: If I record a sequence starting with, say, the note A, I'd like to playback that sequence as recorded by pressing note A. This is where my Moog Sub 37 excels, because it does precisely that. In contrast, for the OP1 (if I remember correctly), and my Keystep, I would have to press the note C for the sequence to play exactly as recorded.
Here are some thoughts on what I have tried with the apps I have:
a) Drambo: quite complex, couldn't quite figure out how to transpose more than one sequence simultaneously by pressing a note on a midi keyboard. I know that someone will probably say that "Drambo can do this" (please tell me how!).
b) Fugue Machine: great, but cannot transpose via Midi input (that slider on the right). It would have been cool to edit the individual notes for the individual playheads (i.e. I don't want to have my bassline or pads play those higher notes in an Arp-like arrangement, which is why I'm looking for another app)
c) Xynthesizr: Very close to what I'm looking for (receives midi input from external synth and transposes correspondingly), but only has 32 steps and allows for only one sequence. I'm currently compensating for this by latching bass notes on the Moog that would trigger the sequence on the Prophet.
d) Rozeta Cells: great simplicity but editing notes is probably not what it was made for.
e) Touchscaper: I love this app, but as far as I understand, I cannot record notes into the sequencer from an external keyboard.
Is there an app that can do these things or am I possibly not experienced enough with the apps that I have? I was looking at Xequence 2 but I couldn't find out much about transposition options. I greatly appreciate your help!
