My very first iPhone/iPod-touch/iPad app has just been approved (yay!)

by Apple and is available at the itunes app store. Check the web site

It's yet another in the long line of "looching" generative/ambient/algorithmic

Why is this of interest to max/msp developers? "ilooch" uses iRTcmix

max/msp as my development environment ([rtcmix~]) to build the essential

music and audio-interactive parts of the app. It's not quit max/msp

directly-translated to iPhoneOS (which would be *really* difficult), but

I made a short demo video of a very basic iPhone app-development process,

it shows what's involved. All the synthesis and sig-processing is done on

the iPhone, it's not an OSC-wrapper for external hardware. Because iRTcmix is

built using XCode and is fully-compiled into the finished app, it (obviously)

meets the constraints for iPhone apps; i.e. you don't have to 'jailbreak'

I hope you enjoy this -- drop me a note if you'd like. Life can be fun!

Thanks a lot for this. It looks really really exciting. I will love to check it out.

My only problem is that my rtcmix~ (and chuck~) has been crashing since I installed the FTM package. I have read an old thread about this subject but it does'nt seem that the problem has been solved. Do you have a solution for this ?

Unfortunately this is a problem that I cannot fix. I think IRCAM is using the same (common) parser-builder that we use in RTcmix (a yacc/lex variant of some kind), and apparently because they are communicating across various objects the main call to the parser is exposed. So when [rtcmix~] calls what it thinks is the RTcmix parser, it invokes the FTM parser instead. And as you noticed this also affects [chuck~], because the ChucK team also used the same scheme. The only thing to do is to move the FTM libs out of the search path when using [rtcmix~] or [chuck~], but that's kind of a pain. Sorry!

I wonder if it would be possible to create a Max patch that changes the search path and excludes the FTM libs at startup.

If possible this patch could be activated when RTcmix~ or chuck~ is going to be used.

Does anyone know if this can be done and how ?

I have downloaded the zip file and tried to compile the source, but I found out in the "phone_libs" folders (both iRTcmix-iPhone-DEV and iRTcmis-iPhone-SIM), they only contain empty aliases. I did double-click "_COMPILE_IRTCMI_" and drag the parent folder into terminal window to compile. Maybe I have missed something.... any insight helps.

Great work!! Thanks for sharing.

Could you re-unpack the .zip file, and then run the _COMPILE_IRTCMIX_ command? When it finishes, do a "select all" in the window where the output from the _COMPILE_IRTCMIX_ command happened, and then paste it into e-mail to me: garton - at - columbia - dot -edu.

I'm really enjoying working RTcmix in RTcmix~. the only problem is it keeps crashing.. normally at annoying moments. I've uninstalled FTM and gabor... are there any more libraries i need to un-install to get it all more stable??

irtcmix works great btw, i'm loving the sounds of RTcmix ( i'm working through all the documentation ) i just wish i was more experienced in actual programming (i'm a patcher person at the minute ) specifically making algorithms and using RTcmix to generate the sound. are there any tutorials on patterns / algorithm making e.t.c. ?
