Hey All,

I am trying to create a piano, but i want to be able to switch between the sounds the piano makes (eg I want to be able to have the piano sound like a trumpet, then a harp, then a piano with button clicks). I have achieved this using BASS.dll, however i am doing it in a very redundant way.

Here is what I am currently doing:

1) Create stream variables for all the sounds (if I have 25 notes on the piano, ill need 25*3 variables for the three instruments)
2) Assign each of these streams to an audio file (75 duplicated lines of code)
3) Have buttons assign a sound to the OnMouseDown of a piano key.

Here are examples of the code I used:
1)Create stream variables: [Example: HSTREAM;]
2)Assign stream: [Example := BASS_StreamCreateFile(False, pansichar('FileName.wav'), 0, 0, 0);]
3)Play stream: [BASS_ChannelPlay(Example, True);]

Clearly, my method means dozens of Copy/Paste lines of code, and since I am using this for a school project, I cannot expect a very good grade for the method I am using. I was wondering if there was some way that I could create an array to assign sounds and such simply by looping through the array.

I thinck it is possible by creating 3 differnt arrays
- 1 for the piano sound (under Type: Piano = Array [1..25]
of string; then under global var: arrPiano : Piano;)
- 1 for the trumpet (under Type: Trumpet = Array
[1..25] of String; then under global var: arrTrumpet :
Trumpet;)
- 1 for the harp (under Type: Harp = Array [1..25] of
String; then under glabal var: arrHarp : Harp)

And assign a variable to declare to which sound file it would be assigned to (I'd use three one for each sound - iPiano, iTrumpet, iHarp : Interger;)

Then for the codes

> iPiano := 0;
> iHarp := 0;
> iTrumpet := 0;
>
> While iPiano < 26
> Do
> arrPiano[iPiano] := (Sound File Name);
>
> While iTrumpet < 26
> Do
> arrTrumpet[iTrumpet] := (Sound File Name);
>
> While iHarp < 26
> Do
> arrPiano[iHarp] := (Sound File Name);

The rest is up to you to try and figure out; GOOD LUCK!!!
