My first post on here so hi everyone, i'm creating a simple control surface in MobMuPlat - 8 sliders to send out midi and control Modul8. I uploaded it via iTunes as instructed but the app just crashes out as soon as i select my patch: black screen > gone...

I was wondering if my version of PD was to blame PD 4.7.1 /Mac?

You might want to see the patch in case there is a bit missing but this crash makes me think 4.7 might not be compatible

try testing on somebody else's phone...that can narrow some of the errors down
I would be surprised if PD 0.47.1 (thats what you meant, right?) was the problem because it seems like people have been using that combination for a while with some success.

It could be a problem with the patch, are you loadbanging lots of stuff upon opening the patch? if so check for conflicts there, see what order things are being loaded in

The 4 crash i have logs all look similar, and i'm not good at reading them. It looks a bit like the patch is asking all the wrong questions. Should use a 64 or 32 bit version of PD?

Hi, could you please post your patch and the full error dump here (or at https://github.com/monkeyswarm/mobmuplat/issues)

Also, are you loading the patch with a custom interface, or by itself (to use the native pd gui)? If the latter (which is always a bit dicey), I'd try the former and see if it loads correctly that way. If so, then it's some case that I haven't handled correctly.
