Asking for a keyboard preview feature

Hey Rui!
I dunno if it is difficult to implement or not, but if you will manage to do this, this might increase usability and productivity of working in Qtractor by a dazzling 200%.

The idea is simple - when you select a midi channel, allow the normal computer keyboard to send midi to that channel, so that if I load up a synth there or a soundfont, I can play it with the keyboard.

This is important, because if you, for instance, are choosing a preset of a soundfont or are tweaking a synth, like Monosynth, you need to always hear how it plays. What can be done at the moment is not convenient:
1. Attach a jack_keyboard to Qtractor and grab keyboard with it. You don't want your keyboard to be always grabbed, so you have to switch between windows all the time, bringing jack_keyboard up, deselecting "grab keyboard" option and so forth.
2. Get some notes into the midi clip and loop it while changing the sound.

So would be great. And, most importantly, when the midi track is selected, you should be able to play it even when Qtractor window is not active, like if you opened a synth window and changing something in there. This is missing in LMMS for instance - when an instrument window is active it will grab your computer keyboard to play this instrument on it, but as soon as you switch away to tweak effects, it stops playing which makes you once more switch between windows. Very inconvenient.

Anyway, tell me what you think.
