not sure how Csound's iOS MIDI implementation is, but an iPhone app can use apple's wireless MIDI -- although only way i know how to get midi to it would be from another iOS device or a Mac.

your question got me thinking of other approaches:

+ use a volume pedal and pass some signal (maybe the looped back output?) into the mic input of the iPhone -- use some logic around an rms opcode or something to trigger your sounds.

 

+ use the accelerometer/gyroscope in the iphone and build some kind of foot lever that you strap the iphone into

+ last i checked, some of those footpedals used for hands-free page turns just sent a "next page" character which you might be able to trap with the sensekey opcode (if this opcode works on iOS?).  

and if there is a bluetooth version then you might be set (or use iPad with camera connector?) 

 + if not, it is also pretty easy to hack into a keyboard and make a trigger to send a single character.

+ along those lines you could try hacking into the "remote control" button on a headset.  the iOS code to trap RemoteControlEvents is pretty straight forward -- maybe someone (me?) could make an opcode for that... (there also might be footpedals for this?)

 -- actually if all you are doing is playing back files you probably can use this approach with the Music app and not even use Csound! :)

(fyi the apple developer program costs $100/year)

Thanks Victor,

is that apple tax much? I don't mind latency much but the reason I was thinking of iOS is because she already has an iPhone.

Best,

Steven and myself were discussing this. We have some material for Android, which one of my students prepared, but nothing on iOS. We thought to put together something, but we have not done it yet.

To deploy iOS apps, you will need to pay the Apple tax though. If you can live with some latency, Android is more accessible.

Nice, that midi to osc convertor looks really handy. 

Are there any online resources for learning the basics of iOS coding? Or better even, csound/iOS?

Thanks

Well there is no way to not do any iOS programming to get this to work.
Unless someone has already come up with such an app.

One option would be through OSC. You can convert MIDI to OSC with this handy device...
http://wifimidi.com/store/ Then monitor the proper port in your iOS app to pick up the data,
then play your audio.

Another option would be to use the iPad camera expansion connector and find a pedal that is
a MIDI class compliant device. Then your iOS app would only need to respond to MIDI messages.

Dear all,

I'm working with a performer who would like to take a couple of violin and tape pieces on the road. I normally use maxmsp for live shows but now I would like to make a little iphone app for her to run the playback instruments directly from her phone, which will be plugged into an amp. The idea is to eliminate the need for a technician and a laptop/interface. I understand this is now possible with Csound but does that involved any non-csound coding too? And how would I go about connecting a trigger pedal or switch to an iphone? Maybe one can build some sort of wireless OSC pedal easily?

Best,
Peiman
