Bernhard, don’t worry, you are perfectly clear and understandable.
I have always been more familiar with the keyboard controllers. I use them when working on with my DAW. What you describe is much more sophisticated and makes the idea of a MIDI harp much more appealing to me.
I have never been against them, but I play Jazz and pop, and I always thought that some of the techniques I use often, like applying pressure to the string between the tuning and bridge pins to bend notes or add tremolo, as well as things like adding vibrato, just wouldn’t work with MIDI. I have found MIDI guitars to have these problems.
But if I understand what you are saying these techniques would work on your MIDI harp?
How about transmitting other sounds from the string? Can samples be created that would allow, say, the sound of a fingernail being scraped along a bass string produced? I use that sometimes, and it works exceptionally well on my electric harp, which picks up all noise off the strings and amplifies it clearly. Of course MIDI wouldn’t pick the actual sound up, but could a sample be used to mimic that?
MIDI has come a long way it seems.
