That idea remembers me at my Thrust sound code: :-)
StartSound SUBROUTINE
ldx AudIdx1 ; 3 determine sound-channel
cpx AudIdx0 ; 3 with lowest prioroty
ldx #0 ; 2
bcs .channel0 ; 2³
inx ; 2
.channel0:
cmp AudIdx0,x ; 4 new priority higher than current lowest?
bcc .noSound ; 2³ no, skip new sound
sta AudIdx0,x ; 4 yes, replace old sound with new one
lda #0 ; 2 and
sta AudTim0,x ; 4 start new sequence
.noSound:
rts ; 6 = 24/25/33/34
By definition, my "least-busy channel" is determined by the priority
of the FX which is identical to the offset into the sound data table.
Have fun!
