A Wurli and a Korg Vocoder?! Oh Paul, what have you done in the 80ties 😛
Cresc + Dim Velocity (Duration) Crossfade sounds interesting.
It seems in general that VSL have done now several things for the user, what he theoretically already has been able to before, while it was for many users presumably more tedious to programm the presets in that way than just to make use of the VSL-Presets or load only those patches which are acttually needed. However the organizing Ideas behind still seem to me always musical reasonable. (Even the "changing bowposition"-X-Fade while to be consequent this would need sulponticello patches to - BTW would it be possible to crossfade more than two patches?)
Still I am pretty curious for the Synchron-Player.
