Using VarPtr in Play staement

[PhilOfPerth]

I'm trying to set the length of notes in a Play statement using a loop and Varptr, but can't hit on the correct syntax. This is what I'm currently trying:

Code: (Select All)

For D% = 1 To 3
    Play "L" + "X" + VarPtr$(D%) + "o3cdefgab"
Next

What am I doing wrong?

I think you need to pass PLAY the whole string - the docs here show that:

Code: (Select All)

'Play scale in 7 different octaves
scale$ = "CDEFGAB"

play$ = "L16O=" + VARPTR$(i%) + "X" + VARPTR$(scale$)

FOR i% = 0 TO 6
    PLAY play$
NEXT

Thanks @grymmjack. I'll play around with that and see what I can figure out.
(as you can see, I'm not the quickest at absorbing new info)!
