@Ali
My next channel, which I am developping right now is a
Midi Input/Output channel called the Midi_IO. With it, users will be able to control Q3D via any external midi devices (Control Surface, Midi instruments, Sensors and the like) and/or vice versa give a Q3D project the mean of controling any external midi devices (Midi Instruments, lighting systems, lasers systems, fireworks etc...) No sounds involved directly.
Regarding V4.0 I am afraid that I am not more in the secret than everyone else
GUI are definitively needed - the same though - don't really know either what is coming - something I know though is that they are a pain in the butt to design and any solutions will be very welcome indeed
Glad to have you on board Ali and also to have introduce you to this great product to which you have really done justice - all the best to you and please continue to amaze us with your beautiful and extraordinary art
