Hey guys, made a basic tape delay for Uni. Worked fine until i tried to create a User Interface, which seems to have killed the patch. By which, i mean that no audio is read in or out of this particular PD window. I've tested other projects of mine (delays, mixers, synths etc.) which all work fine. There is no change in audio preferences between the tape delay or other sessions, which suggests a patching issue to me. I'm pretty stumped. Can anyone shed some light on this? If there is any input on why its not working and how i can fix this, it would be much appreciated. I'm not a PD expert by any chance, so please explain anything you can suggest simply haha!
