Hi Bachus,
Don't think there's a whole lot of difference in key touch, vs articulation and 'the moment'. I, for one, enjoy both weighted and soft touch boards, as I'm usually affixed to the end result.
What does annoy me and ruin the moment, are awful keyboards that just cannot get the keys to respond correctly. I dump those boards asap.
Its not meant to be about keytouch, but about touching the keys
Do you ever drum on your keys..
And when playing a string instrument get that natural feeling of wiggling your finger to try amd get vibrato?
