Hi,

I was just wondering if anyone knew of a way in which I can count all the notes played on a MIDI keyboard, and then look back and see how many times each note had been played.

I started building a patch but I was having all kinds of issues, and then I thought I can't be the first person wanting to do this.

Any help would be greatly appreciated!!

Many thanks,
Toby

Apologies if I'm posting in the wrong place, I'm new to this forum.

Hi,
I would start with something like this :

Thanks LucienR, I will give that a try.

Here's the patch I've been working on this morning - any improvements you can think of would be greatly received.

selecounter.pd

Thanks,
Toby

Hi Toby

The patch you uploaded looks like it will work perfectly well, although as you can see, Lucien's solution accomplishes the same thing with many fewer objects.

A few other suggestions:

1. The number atom in your "countfloat" subpatch is obsolete. The number atom is basically just a GUI object, useful for data entry and retrieval. Putting it in the middle of a patch will only cost extra CPU.
2. It looks like the reset button will send out a 0 but won't actually reset the counter. Unless this is what you want, you should connect the 0 message to the cold inlet of [float] also.
3. Rather than copying the subpatch again and again, it would make sense in this instance to create an abstraction. You can learn about these here: http://en.flossmanuals.net/pure-data/ch042_abstractions/.

Hi Liam,

Thanks for your feedback. You advice with the number atom is very helpful, although I do usually remove them later, when I'm patching I like to see everything that is happening. I guess I weird like that, but I didn't realise it was using CPU so thanks!!

I will also give an abstraction a go! I'm not new to Pd, I've just always used it in a very limited way, so I've never tried this.

Maybe you could help me further.

I'm trying to use a PNOscan which will trigger previously recorded clips. However the piece the pianist is playing is very difficult. So, I thought it would be best to count the notes as she plays and then use some sort of conditional logic to say, if note 64 is played 7 times trigger this audio.

So I guess my question is, clearly Lucien's method is better, but how do I take the information from the Array and place it back into number atoms (like in my patch) so I can easily see how many time each note has been played and then write the appropriate conditional logic?

Once again, I'm very grateful for any suggestions/help anyone has.

Many thanks,
Toby

Also this site/forum is amazing so thanks again, again.

@tobyclbain Hello Toby........ if you want to use the number boxes later in your patch then you will have to write out the array (in much the same way as you have already done) or send a list to the logic that you are planning to create.
If you just want to read the data in the array then you can "right-click" the array and then "properties" "open list-view"......

The best solution I can think of is to use [expr], like this :

In my example, you have three distinct bangs : when notes 64, 65 and 66 have been played 7, 5 and 6 times respectively. One issue you might face is that if the pianist misses a note, it won't work. I've never worked on score following, so I have no solution in mind. Well I have one, but it would require a lot of work : you would have to create a patch that "guesses" the missed notes.
Anyway, I hope this helps.
Lucien

This is great! Thank you very much for your help - no doubt I'll have more questions later on in the project - but this should keep me busy for the time being.

Thanks,
Toby

You're welcome, I'm glad I can help. I had never heard of PNOscan, looks interesting. If you need further advice feel free to ask.
