sflooper is a cross between sfplay and flooper, but i think there is an issue
with it. 

In Blue, i have 2 Soundfont instruments, one using sfplay and the other is
one using sflooper. They both play the same preset with 4 different
velocities.
Apart from the looping points, they should sound the same.

sfplay works fine, but sflooper produces sometimes weird effects - i think
it is "borrowing" samples from other presets sometimes. 

I have attached the csd, produced by Blue. The csd looks a bit strange
because of all the extra Blue stuff but i tried it out from the commandline
and it produces the exact (weird) result with sflooper as it does using
Blue.
The Soundfont used can be found in the examples folder from the manual.

I can give a bunch of other examples for this, but this is a Soundfont
distributed with the manual and does not need to be downloaded separately
and has no further copyright sorrows...

sflooper4.csd
  
SFlooper.wav   

and here is the result using a large GM Soundfont i found on the internet.
This shows the same issue with sflooper:  SFweird.wav
  
Same procedure: first 4 notes with sfplay, then 4 notes with sflooper

Hi, 
i realize my example is ridiculously long, with too many variables; today or
tomorrow, i'll make a new basic example that shows the same issue...

okay, i now have a short and simple example that shows the issue with
sflooper.

Soundfont = sf_GMbank.sf2, to be found in
https://github.com/csound/csound/tree/develop/samples
It's a rather small Soundfont but i found that preset 3 shows the issue;
suddenly there is an extra piano sound, borrowed form another instrument?
Some leakage?
Other, especially bigger Soundfonts shows more examples of this same issue.

csd =  sflooperissue.csd
  
result =  sflooperissue.mp3
  

First sfplay plays note 60 with 4 different velocities, then sflooper does
the same.
The issue can be heard in the first note of sflooper.

can someone check this out please?
