As I said before : more aftertouch is a waste of energy and time. Why? Because aftertouch is a movement AFTER all 'the work' has been done. What is 'the work'? It is the mechanical work an action has to perform in order to cause a=20= piano hammer to go up, hit the string(s) and come to a rest in the back=20= check. meanwhile, we hope that the jack did escape from under the knuckle=20 without causing any trouble for the work the hammer had to do. If all that has been accomplished, 'the work' has been done. Aftertouch comes after the work. It literally means that you do some=20 work for nothing. Why would one do want to do something for nothing? Because it is safer to have at least a tiny surplus of movement because=20= many actions have problems more or less. Problems 'more or less' can be caused by a multitude of reasons, which=20= most often can be combined in three conceptions : worn parts, bad=20 regulation, friction. If this "work for nothing" is incorporated in 'the work', the=20 mechanical way, it always causes a more or less softer touch, caused by=20= loss of energy, caused by : worn parts, bad regulation, friction. Actually, aftertouch is bad regulation, because it is a loss of energy,=20= and thus time. But it is necessary, because an action regulated too sharply, is highly=20= dependent on the newness of the action parts, the regulation of the=20 action, and friction within keyboard and action. Because most actions (generally speaking) are so so so regulated,=20 always have friction, and usually are not new, a minor aftertouch is=20 necessary to compensate for these. A very small aftertouch is called a 'hard landing'. It means that a very small part of the 'action', 'the works' is wasted. It also means that all the movements of keyboard and action combined=20 are translated into the finger of the technician/pianist as working=20 very directly, and thus very efficiently. Usually a hard landing is translated in an aftertouch of between 0 and=20= 0,5 mm. Many pianists prefer this 'hard landing' because the action feels very=20= precise, and that means that the pianist gets the impression of a fast=20= and precise working action. In other words : the pianist feels that he/she plays on a very sharp=20 and trustworthy piano. The technician though, has to re-regulate this instrument after every=20 concert. A medium aftertouch is a little safer for the pianist and for the=20 technician, because of the slightly bigger aftertouch. A medium aftertouch is typically 0,5 mm and is called 'medium landing' It means literally that after the mechanical work has been done=20 (including bad regulation and friction) there is always that small=20 surplus of mechanical 'safety', meaning that the jack has a little more=20= space to come out from under the knuckle, so that the hammer will not=20 bounce back on the jack. This extra movement, this waste, will however cause for a softer=20 feeling. A big aftertouch is called a 'soft landing'. It only means even more mechanical 'surplus', mechanical 'waste' and is=20= translated in an aftertouch of 1 mm or more. I can not imagine why any pianist wants a soft landing, but they are=20 there. We have a saying : "customer is king". If the customer wants a soft landing, we'll let him/her have it (as=20 long as they pay). A soft landing is the ultimate waste of mechanical energy and time. Why time? because the movement in the action is delayed. This delay causes the feeling of more softness. The more aftertouch, the more softness. You still don't believe it? Try it out for yourself.
