Grand Touch

[David Love]

With respect to the question of how many leads it has as much to do with
position as number and really boils down to the overall front weight of the
keys.  If there are a lot of leads or if they are all pushed way forward on
the key, a high measured front weight can introduce inertial problems such
that even if the static weigh-off is light the dynamic performance can
suffer from a feeling of sluggishess.  That's why overcoming weight problems
by simply adding more lead can be counterproductive.  How many leads and
their position in the key will give you a quick indication if there might be
a problem in this area.

Well, really is it simple - how many leads? My recollection from Stanwood
classes that I have attended is that ideally an action will have three - two
- one - zero lead in keys running from bass to treble. The implication is
that if more lead is required, then maybe action geometry needs to be looked
at. I don't know that four leads is any death pronouncement, but it may be a
reason to look closely at many factors.

Yes, a rather vague and not very helpful statement Terry, I agree.  But how
do you answer a question such as  'how much lead is there in the keys?'   If
I remember rightly there are 4 in the lower bass.
