Hi,

I made a minimal example using the 'delay' opcode:

sr      =       44100
ksmps   =       1
nchnls  =       1

instr 1

       a_input  in
       a_del    delay   a_input, .5
                out     a_input + a_del
endin


I snap my fingers in front of the mic, and I get two strong
pulses, a half second apart as I expected, but then, in the
style of a guitar effects box, the two are repeated at time 1.0
at about half volume, then again at 2.0 at about half volumme 
again:

| |
| |
| |
| |
| | | |
| | | |
| | | | | |
| | | | | |
-----------
0   1   2

At first I thought that this was normal, because I was monitoring
in the same room as the mic through speakers.  Then I turned off
the speakers and put on head phones.  I can turn the headphone
volume way down, and still hear this, so I don't think I'm bleeding
through the phones (The decay is always similar no matter the volume)
and what's more, I can monitor the mic input on the computer, and
can see that only the first snap registers on the VU meters.

I was expecting to hear only two snaps, and was planning next
to feed the output to a global variable in order to achieve the
movie/guitar effect that the opcode seems to be delivering on 
its own.

Thanks,

Tobiah

Sorry,

I must have been feeding some of the output back into the input
from my hardware or software mixer.  I fooled around with those,
and the orchestra works properly.
