Kawai K5000 series

Thanks for mentioning that. I have had a look at
a number of such tools, but I haven't heard of this
one yet. Do you know any URLs for more
info?<br><br>What I have in mind is to use pure harmonics, i.e.
making sure that all frequencies relate to each other in
simple ratios. That's naturally the case, but not so
simple if you combine two or more sounds. As long as
there's just one tone (with its harmonics) it's indeed
simple, one can just gradually shift all frequencies
higher or lower. But imagine you have a melody with a
pitch glide, while the background is built up using a
number of sounds. Imagine that the background stays the
same. As long as there's no glides, the melody tone can
co-incide with one of the harmonics of the background
sound. What I want to do is to use glides in the melody,
while maintaining as much harmony between the melody
sound and the background chord. That can be done by
suppressing some harmonics at some stage during the glide,
while increasing the volume of others, or even by using
specific harmonics of the background chord (at some stage
during the glide) to replace some of the harmonics in
the melody. Until now, I have only managed to work
out a step by step shift in frequencies, rather than
a smoother glide. <br><br>I'll let you know if it
works out to something that's interesting to listen to!
