First of all, I want to thank everyone for the tremendous help you guys gave me to start PD a day or two ago. I think parts of PD have finally started to sink in. Whoever told me not to think of PD so procedurally, or orderly, really helped. Right now, I am getting the benefits of my labor by listening to a loop that goes from midi sound 50 -100 then loops again... and again..... Alright, now for the stuff I don't get! So, my next project I would like to tackle to better understand PD is to have it play a simple midi C scale.
Just send 60, 62, 64, 65, 67, 69, 71, 72 to [mtof]. Or better yet, send 0,2,4,5,7,9,11,12 to [+ 60]. You may want to search Google for Peter Elsea's Max tutorials on pitch (and rhythm and chords later, too) (e.g. ftp://arts.ucsc.edu/pub/ems/maxtutors/)
Some of the things that I want to understand better is the 'select' object, and what happens when an outlet is connected to it, how to use the equality (>, <=) symbols accurately, and how they work in PD. I have already looked at the examples that came with it, and they just confused me: When I took them out at started it over, it seemed to work just fine. This is the 'more counting' one, and when I remove the >= 0 boxes, it still works, plus they're not really explained at all.Thanks again!
[>] and so on work by sending either 0 for false and 1 for true comparisons. [> 10] compares to 10. You can overwrite the stored "10" through the second inlet.
Select converts selected messages to bang-messages. [select 0 1] can be used to convert a 0-message to a bang at the first outlet and a 1 to a bang at the second outlet.
[select] and a comparison together form a kind of if-else-conditional:
if (x > 10) then do bang1 else do bang2 end
in Pd would be:
"float x" | [> 10] | [select 1 0] | | | "bang2" "bang1"
