I'm trying to improve my messy approach to Pure Data so am after advice. I am controlling 8 toggle boxes (which turn on and off an effect) via a keyboard note.

To do this I am currently using, for all 8 effects, an integer increment when the relevant key is pressed, which is then divided by 4, and sent to Sel 0 1 2 3, to get the on event of the key (event 0 and 2). Then sending a Sel 1, or Sel 0 to the Toggle. As I'm doing this 8 times it looks and seems very messy. But at least it works I guess.

Any easier way to do this?

@donnerbono Hello....... if you post your patch (or that part of it) that will be a lot easier to understand!

This will have at least 7 effects that I want to turn on and off with 7 different keys on musical keyboard. Just seems inefficient to have 7 integers incrementing to handle simple on off operation. (I"ve only shown one on patch).

Can anyone recommend a nicer way of doing this?

@donnerbono I might be wrong but you should be able to do it simply like this.........

Like the cleaner Select method that looks much better.!! I'll use that.

Unfortunately, when you take finger off the key it sends a note event (velocity 0 I guess) so turns it immediately off again. If that makes sense? So it's the 1st and 3rd out of 4 note events you need to capture.

[r notes]

    [unpack f f]
    |          |
    note       vel
               |
               [route 1 0]
               |    
              [bang(
              |
            Toggle

@donnerbono Try this..........multi_fx.pd
an edit: I am assuming that [r note] is receiving messages like [62 100( followed by [62 0( but maybe that is not the case......... here is the same patch with [notein] hooked up directly, which should work...... although you might need to filter for the midi channel number.....

That's awesome!!! Thanks. This patch looks so much better now so I can see what else I'm doing.

And it seems the pipe handles a longer key press event a bit better. At least I think that's what it is doing?

@seed

Thanks too! I just used the route 1 0 to give an output from one of the toggles. This would not have come to me without seeing this.

Having a productive evening now...
