Hello, well my question is simple: is there something I have to do to build an app that have externals (i.e. "+pitchdelay~", from Soundhack)? Or just I build it as always and it will work in any computer?
If your externals aren't getting included, either use "include file" or "include folder" to make sure. I tend to be pretty heavy-handed about this.
Alternately, you can also copy your externs into the app bundle. I don't recall off-hand the exact location, nor what the equivalent for Windows is, but dig around the archives or experiment if you'd prefer that approach.
