SOUND KIT

B.J. Kamphuis has been a regular contributor to ZXC for many moons.

This neat little routine extends the Spectrum's beep in a simple and

easy way.



It is located at address 32000 to allow it to work on 16K machines

(are there still any around?) but can be relocated to any address. I

would suggest 60000 and to do this change line 30 to CLEAR 59999 and

all numbers 32000 to 60000.



To use it in your own programs include lines 10 to 70. You can of

course put them as a subroutine at the end of your program, and place

your program at lines 100 onward.



The lines 100, 110 and 120 are there to demonstrate some of the sounds.



To use the code RANDOMIZE USR 32000 (or 60000 or whatever address you

used) and follow it immediately on the same line with :REM !x,y,z



The x and y are the length of the note and can be any of the

Spectrum's numbers, letters or keywords.



The z is the pitch of the note and the only restriction is that the

CODE of the z value is GREATER or EQUAL to that of the CODE of the y value.



Note that an exclamation mark must also follow the REM.
