I noticed patches created in Max 5 or previous versions just won't work properly in Max 6. Some patch cords are just messed up.
This is annoying. For example, I am using the rev1~ abstraction from IRCAM in Max 6 and the reverb effect sounds like the effect of freqtshift~ instead of original reverb effect. The same patch and abstraction work fine in Max 5 and in previous versions. Similar problems happen to my other old patches when they are opened in Max 6. I fixed some of the problems by delete some patch cords and re-connecting again. But this would take a lot of time to debug all the problematic patch cords.
Is there some smart way to correct these problems ?
