Display active keys without playing a note?

[the-t-in-rtf]

In my own work, I have a single page that is integrated both with a MIDI controller and with an onscreen instance of sisiliano. I would like for the keys hit on the MIDI controller to be highlighted onscreen, but without necessarily playing a note. I would like to be able to optionally specify the color, so that (for example) multiple collaborators could see the notes they are hitting on a single sisiliano instance. Anyway, is anything like that possible? If it's not and you're open to the idea, let me know, I might be able to submit a pull request.

could you please explain more... do you have already done the required change in a fork. If so I can have a look

I am using sisiliano in combination with Flocking and a MIDI controller. I want to enable collaboration between one user (using the MIDI controller) and another using a web browser. I want to be able to display the fact that a key is active without doing anything that would result in the note being played twice.

I have not prepared a pull because I want to make sure it's not already possible.

understood @the-t-in-rtf

We can do that by adding an event. The current implementation has not provided that yet.

It sounds like you'll want to introduce a slightly more fine-grained semantic for "selection" in the keyboard. At the moment, when a key is "selected," it's also "active." But it sounds like @the-t-in-rtf wants to be able to select or highlight a key on the keyboard without activating it. I imagine that, in the long run, we'll want to modelize the keyboard so that it explicitly keeps track of which keys are active (and in Tony's case, which ones are selected/highlighted).
