PC keyboard...

Post by tester »

I'm checking the standard PC keyboard support using example schematic, and have few questions, maybe someone worked it around earlier.

Attached schematic has following issues.

If two (or more) PC keys are presset at once, and one of them is released, then the output resets to nil.
How to prevent it?

Some sort of buffer/rule would be required to turn on "last pressed" key (from all keys that are on) when a key is released.
Puff... Anyone played with this stuff?

(turned on midi in prevents FS keyboard shortcuts to work inside the schematic).

Not to mention that it would be useful to assign midi keyboard too (one octave per notes, one octave per H's and one - the pne before notes - for o's). But I guess this is simpler.

I think I found a simple way to deal with PC keys. Now it works with multiple key (at once) setup.
