Hi,

the Virtual Keyboard does not appear to work well on the Mac (terminal); it shows an empty window and it can be played by hitting the invisible keys...On Linux (terminal) the Virtual Keyboard works fine.

Can someone try the example out on a Windows machine, using the command line, to see if it works?

Does it crash on Windows or just doesn’t work?

On the Mac it’s not going to work correctly as the FLTK widgets no longer work on MacOS. We will have
to retire the FLTK widget opcodes or replace by something else.

I just tried the example that ships with Csound for the virtual midi keyboard, virtual.csd and it crashes out for me. Looks like a portaudio error though.

Hi,

the Virtual Keyboard does not appear to work well on the Mac (terminal); it shows an empty window and it can be played by hitting the invisible keys...On Linux (terminal) the Virtual Keyboard works fine.

Can someone try the example out on a Windows machine, using the command line, to see if it works?

Victor, 

It might be best to consider retiring the FLTK opcodes, especially now that we have Cabbage and the Widgets in CsoundQt as well.

In fact, there is a nice virtual keyboard, that does work, in CsoundQt.

But, is there a chance that a virtual keyboard could be designed, that would work in the terminal, that would not be FLTK based?

- or should we just recommend, expect and perhaps show how to use Keyboard Apps and Utilities?

On the Mac it’s not going to work correctly as the FLTK widgets no longer work on MacOS. We will have
to retire the FLTK widget opcodes or replace by something else.

I have many older compositions that use FLTK widgets from the command line (and intended primarily for Windows). How would these be affected by such a move?
