Re: [PD] help on random samplePlayer - Pd-list

      Hi Frank, hi Andre,
...
...
I see there is some need for an xgroove~ improvement. I will see what i
can
...
do to achieve an interpolated position change. This is not too easy, but
i'll try to tackle it.
Here's a solution to non-clicking position changes (for xgroove~ and
others).
It seems that the only reasonable (and straightforward) way is to fade out,
change the position and fade in again.
I decided not to implement it into the external as it is fairly easy to
implement as a pd patch.
Here is the abstraction ramp.pd. It takes a float as argument which is the
fade time in milliseconds. You can send all messages for xgroove~ through
it, it will recognize the pos message and output a ramp to the left outlet~,
all messages are output unchanged to the right outlet.
