Play alonga CPC This program enables you to use the keyboard of your CPC Amstrad to play tunes and entertain Auntie. As it stands the assembler listing is written for the CPC 6128 and 664 but it should run on the CPC 464. The Basic listing is designed for the 6128 keyboard: It will work with the 464 but some of the keys are not in a logical place on the keyboard. When typing in the Basic listing you should be especially careful with the last number on each data line. This is a subtotal for the line and is your guarantee of easy debugging. The program stops and informs you if there is an error, and will give you a line to check. If you get an error in the sum total then you have to check all the 'data lines. Provided everything is OK the machine code is set up and called. The screen clears and you are asked if you wish to use the preset envelopes built into the program - hit Y or N accordingly. Next you will get a screen with information about which keys do what. You can use up to nine tone and amplitude envelopes over seven octaves. The Caps lock produces the note G and that row of keys - right up to the f3, which is the B - corresponds to the white keys on the piano. You can play up to three notes at a time which is handy for chording. It really sounds best through a quality amplifier in mono mode to centralise the channels. That's when you realise how good the Amstrad sound system really is.
