Hello Steven

It seems to work well. The only problem is that you used [delread~] in you 
abstraction, which is not very suitable for variable delays. The original [vd~] 
object is better for this, and if you use this one inside your abstraction 
instead of [delread~], and if the "crossfade period" is inferior to the fastest 
delay change, you get no doppler and no clicks.

I posted you the [vdx~] abstraction, which is YOUR abstraction using [vd~], and 
a little example (see attached files).

Thanks a lot for your help,
