Hi Steven,

I'm finally on the Csound developers list as of today. In case it's not too late for 
5.18 here's feed-back on my experience of iOS SDK 5.17.

I was able to launch the Csound app on the iPhone and use it. Most examples 
work very well though the sound levels are extremely quiet. Three files also 
reported warnings during build 

'Semantic issue Method possibly missing a [super dealloc] call'

They were: - SliderMidiWidgetWrapper.m, ConsoleOutputViewController.m and 
LevelMeterView.m

And there was one last warning

ld: warning: directory not found for option '-
L/Users/gregschiemer/Documents/iOS/csound-iOS-5.17.3/Csound iOS 
Examples/../cs5iOS'

This may have something to do with my version of iOS (4.3.2) or Simulator (5.1). 

And here's a review of each example.

1, 2, 3, 5, 8, 9, 10, 12, 13 and 14 all work fine on the iPhone as long as you use 
through earphones. This is a problem for apps that use iPhone speakers. Is there 
a way to fix that ? I tried a few things in CsoundObj.m

(1. Simple Test 1, 2. Simple Test 2, 5. Ping Pong Delay, 8. Csound Haiku 4
9. Record Test, 10. MultiTouch XY, 11. Waveview, 12. Audio File Test
13. Console Output (I tried it successfully with several .csd files), 14. Pitch Shifter.)

3. Button Test - single note played once when Value Button is touched, but hitting 
the Event Button caused the UI to vanish.

4. MIDI Test - sliders appear to be completely inactive.

6. Harmonizer - sliders are very sticky when the harmoniser is On.

7. Hardware Test -  after a few seconds it hangs with sound still playing and losing 
its ViewController, at which point simulation can only be stopped from Xcode.

When my app is all finished I'd be happy to add my contribution to a future release 
as my way of saying thanks to people in the Csound community like yourself.

Cheers

Hi Greg,

I'll reply in-line below.  Thanks!

I've fixed up these warnings and will push to git shortly.

I'm not seeing this here. I think I may have fixed this in the 5.17.11
release.  It's a minor warning and shouldn't cause any issues and is
hopefully fixed already.

I'm currently testing just on simulators.  We have some hardware
devices to test on campus but I'm not in possession of one at the
moment.  The examples are working here on the iPhone and iPad
simulator.

I am unable to reproduce this.  This may be an iOS 4 issue, but
unfortunately I don't think we have a device that has iOS 4 to test
on.

> 4. MIDI Test - sliders appear to be completely inactive.

This example probably shouldn't be shown on iPhone, only on iPad.  It
uses MIDI input via CoreMIDI and camera connection kit (or Alesis
iDock) to perform, and I think that it only works with iPad's.  On the
iPad, there is a virtual keyboard that one can play on-screen.  (I
think we never adjusted the UI to show the Virtual keyboard on the
iPhone). Testing here with iPad simulator, the sliders were working to
adjust synth parameters.

> 6. Harmonizer - sliders are very sticky when the harmoniser is On.

This may be a performance issue with your device?  I wasn't able to
reproduce using simulator.  Are you using an older iPhone perhaps?  As
far as I remember, Csound doesn't really work all that well on iPhone
3/3g, and the harmonizer example especially as it using FFT (pvs
opcodes).

On the simulator (btw, using iOS 5.1 simulator for iPhone and iPad) I
am not having issues.  I'm downloading the 4.3 simulator package now
and will retest this and the others.

Contributions are always welcome!

Just to follow-up, on the 4.3 iPhone simulator, things seem to be
working.  It may be a hardware device issue.  Which iPhone were you
testing on?

The Apple docs do mention that the simulator is not that deep - it does 
not simulate the hardware. Any iOS audio is handled by the native 
CoreAudio, at full host machine speed. So testing on the simulator 
cannot be relied upon to assure correct operation on a device. There 
will always be a need not only to run on a device, but to debug on a 
device too. This will be especially important if the device CPU is being 
driven close to the limit.

Yes, this is understood.  I can not test on devices I do not own
though, and so can only report if I can reproduce with what I do have
available. At the company I used to work for, we tested the iOS app
often on simulator and hardware and more than once had issues only
appear on hardware.  There were also some bugs that happened on
specific iOS versions, whether it was simulator or device, and some
that only happened on device, but not on simulator. Therefore, I am
suspecting the issue is device-specific (which could also be
sub-divided into all devices with specific iOS, or particular device
with specific iOS...).

Oddly, I had felt more at ease with Android apps we worked on at the
time, despite the issues that popped up.  We tended to get less device
specific issues and just had issues dealing with the different DPI's
and resolutions that we hadn't accounted for.  The only times we had
really strange device specific Android issues were with the low-budget
devices.
