[Csnd] Question about the Sensekey opcode

The Csound Mailinglist
#1

Hi all,

I’d like to use the Sensekey opcode to monitor keyboard input. However, I want to be able to use other keys than alphanumeric ones, like the arrow keys, for instance. Is this possible? The examples that come with the reference manual only show letters being used, so that’s why I’m asking.

Best regards,

Susanne

On my system it works, however the cursor keys output values 65-68, i.e.
the same as A-D. Modifying with shift makes no difference.

HTH.

Best wishes,

i once wrote a udo to work with this in csoundqt:

not sure it works on other frontends, or in the terminal, but it may be helpful.

Great stuff! It works for me. All cursor keys are returned as negative, everything else positive.

good to know --- thanks!

Some time ago, I wrote an opcode for fetching multi byte keystrokes and return them as a unique number. Works perfectly in Ubuntu and basically in Windows (function keys are coded improperly there)

See the attached example, maybe it's helpful. Needs no QT, works in plain terminal Csound (which is my favourite :slight_smile: )

Btw, is there a way to suppress the key annoying key echo in the terminal? Didn't find anything...
