sfx(id,note,channel)

id [0..63] == -1 by default to stop playing sfx on the channel, so if you call sfx() it means stop playing on 0 channel

note [0..95] we have 8 octaves each has 12 notes

channel [0..3] 0,1-square 2-triangle 3-noise

-- simple note playing demo when a button is pressed
-- sfx(0,44) takes affect only first time, you have to call 'sfx(-1) sfx(0,44)' to reload sfx
t=0
x=104
y=24
function TIC()
 cls(15)
 spr(1+(t%20)/10,x,y,1,4)
 print("Press any arrow key!",64,64,0)
 t=t+1
 if btn(0) then sfx(0,44)
 elseif btn(1) then sfx(0,45)
 elseif btn(2) then sfx(0,46)
 elseif btn(3) then sfx(0,47)
 else sfx(-1) end
end

Also, you can wait until sfx is playing

t=0
x=104
y=24
d=0

function play(note)
 sfx(-1)
 sfx(0,note)

-- wait 30 ticks to start playing new note
 d=30
end

function TIC()
 if d>0 then d=d-1 end
 cls(15)
 spr(1+(t%20)/10,x,y,1,4)
 print("Press any arrow key!",64,64,0)
 t=t+1

 if d==0 then
  if btn(0) then play(44)
  elseif btn(1) then play(45)
  elseif btn(2) then play(46)
  elseif btn(3) then play(47)
  end 
 end

end

So, I'm going to make a sfx demo with the next version then.

Thanks
