There is a section called Max 6 Help but it is really an introduction to general principles rather than a tutorial. There are helpfiles and references for all the new objects but I do not think they have been integrated into the tutorials yet.
For example the eye icon that used to open help patchers is still in Max 6 documentation but it has no functionality... just a dead icon.
Also i looked at the wavetable tutorial (MSP tutorial 3) and it is the same as Max 5 with a picture of Max 5's object palette and no mention of the fact that there is 64bit audio in Max now which should mean larger wavetables are possible.
My impression also. Which means, effectively, that the software is still in beta. Misleading, as I have suggested it for the use with the students. Will have to cancel this advice for the time being (with some damage to credibility) because the current state will only serve to scare away the beginners...
So, look forward to comprehensive documentation, tutorials and commented examples, off and online.
