@whale-av No, it can not work although I created [tabwrite] after the array [a2].

Hello, could someone tell me how to implement this step? A FFT from data in array 1 to array 2. Error here shows ,a2: no such array.

@whale-av Sounds reasonable, thanks again.

I know the basic concept of GOP,however I still do not know how to achieve the same operation as pic shown above(which is come from Pd_intro,although it is comprehensive, but it does not include anything in detail) From my view, A , B and C are all connected to my abstraction, as you say array can not have connection... Maybe A B and C are not arrays, right?

I already create the abstraction (my-tabosc2), but I can not connect it with the array as shown in the pic, how to do that?

@whale-av Cheers~ I skipped this before .

Could someone tell me how to test the simple MIDI monosynth patch listed on PD_intro.pdf to get some feedback or result from the following patch ? Because I am a noob and don't know how to set the notein. I do not have a MIDI keyboard by the way...

@whale-av The table oscillator works, thank you very much!

Hello, I am a beginner of Pd. When I try the patch shown on pd_intro.pdf, it seems not working as I copy exactly the structure of the table oscillator. Could somebody tell me how to fix it? B array seems dead.
