I guess GoAsm woes or the Hp Pavilion

; Been a long time since I wrote this system and can't for the life of me
; remember how I arrived at the noteC3 thingie.
; Same for the Playnotes.
; This uses the Midi disaster.

; When I wrote this system in Windows 98 32-bit, the sound worked just fine.
; It also worked in Vista 32-bit.
; It also works in Windows 7 32-bit using MASM32 on my Hp Pavilion 64-bit puter.

; THE SOUND WILL NOT work in my converted to GoAsm 32-bit version on
; the 64-bit Pavilion or on a Windows 7 32-bit puter. 
; In the (noteC3) I have no idea how I got the "7f" or the "90".
; The 3rd byte is the pitch of the note. Like "30" represents the note "C"
; 3rd octave. 

; two octave scale C to C

interesting to see midi pay notes from memory
i would like to see the code when you get it working   :P


Problem solved.
See the same thing in the GoAsm forum.
