I’m starting to work with long delay lines. Csound is perfect for the job.
Here’s my first recording of a performance

Hi Tarmo and friends,

thanks for your encouragement.
I used a Nord Lead to play (the main reason being that I had it up from the lab and was learning it, making patches etc
but in principle any instrument with wide enough spectral palette would do for me).

I have been thinking about this process for a while and always wondered about how best to do it. Starting from the
principle that I have any kind of delay line possible I did a few tests with a single delay feedback with a tone filter (fixed at 10K)
in the loop (because I thought modelling losses would be an important thing). That seemed to work. So I added another
one and crossfed its outputs. 

This is the basic idea for the instrument, which is very simple. I added a highpass in series and controls for the cutoff, plus
a switch to turn the input on/off. So I can create the pattern and then solo on top (like Fripp did), but I also can increase
the losses (both from the top and from the bottom) to clear the delay lines. I can then transition from one section of the
performance to another. 

adel1 delayr gigm*gigd
afil1 tone adel1, k1
afil1 atone afil1,k3
adel2 delay a1*k2 + afil1,gigd
afil2 tone adel2, k1
afil2 atone afil2,k3
delayw a2*k2 + afil2
ap = 0.5 + oscili:a(0.5,1/(gigm*gigd)) 
al,ar pan2 adel1,ap,2
al,ar pan2 adel2,1-ap,2 
al2,ar2 reverbsc al*0.5,ar*0.5,0.7,5000 
out al+ar2,ar+al2
 
The panning needs to be revised and I can see now another problem: I had a typo in the code where one of the panners
ended up fixed so only one image moved, when the two should have done. I'm thinking I should try 8 crossfed delays and
8 speakers using VBAP.

The delay lines were 12 seconds and 12*gigd, which is the golden mean (I could not think what ratio to use, so I used this,
quite factitiously).

Anyway, it might get somewhere.
