Hello,

I'm working in clone kslider object from Max 7. I have some advance with the help of pd-list guys. For details see:
[PD] Patch With Loadbang Loses Data Structure
and
[PD] How To Map GOP Size Dynamically

Now I have this patch: kslider_draw4.pd
wich have some problems like:

• undesirable click more than one key
• error message on pd window when running in multiple instances.

Any advance are welcomed!

@emviveros The errors are because you still have some sends and receives without $0. You can (sometimes) find the last error with Find > Find Last Error.

To reset the previous key you can use something like this: lastpointer.pd

The first input opens the spigot and stores the current pointer. The next input with different pitch sends the last pointer and stores the current.

You can use the last pointer to reset to default color.

Very nice project!

@emviveros Sorry, i got you wrong.

The effect that you can click more than one key is surprising. It goes away, if you set the width of the filledpolygon to 11, so that you have a double line between the keys.

@ingox, first

Thanks a lot!!

Now, I have no errors in pd window! thanks for the Find -> Find Last Error TIP!

Concern to mouse click selecting more than one key, I make a test and have some strange behavior...

I draw the keyboard without bounds

and in black key bounds I can select a white key simultaneously!! So weird... :/

Here the patch => kslider_draw4.1.pd

I will report it to pd-list, sounds like a bug for me.. I don't know...

Wherever can be exist another solution for this problem. Once I need to enable mouse click and drag to press the keyboard keys dynamically, the color change behavior can be controled with mouse position tracking in GOP.

For that I think:

1. Use external [iemgui/iem_event] to track mouse in GOP

2. Use [cyclone/mousestate] to track mouse click
   2.1 when click create a tiny scalar with data structure on mouse position
   2.2 map x y pos of tiny scalar
   2.3 mouse click off destroy tiny scalar.

The think 2 are better, once I want to submit these object to cyclone library.

I don't find documentation to delete scalar from data-window yet. Any documentation I lost..??

Thanks again!
