Hi Atte,

something like this should work:

imaxdelay = 5; seconds
kdelay = 1; seconds
kfeedback = .5; 0-1
               ; 0 = no delay in output
               ; 1 = constant feedback, even if a_the_dry_signal stops

               ; sounding
asignal = a_the_dry_signal

afeedbacksig    init    0
abufout delayr    imaxdelay
atap      deltap3    kdelay
delayw    asignal + afeedbacksig

afeedbacksig    =    atap*kfeedback ;used in the next k pass

out asignal

bye,
Iain
