Title: A question about the PLAY function
Post by: Kris01 on September 01, 2019, 02:58:16 pm

Is there a way to play multiple "voices" with this function? I know you can add a comma and it will play several notes simultaneously. What I'm asking is if it's possible to play notes from a bass clef and treble clef together (with different melodies). See attachment.

How would I code this?

PLAY “CEG”

Plays do, mi, sol, in sequence.

PLAY “C,E,G”

Plays a chord.

Right, but how do you keep the half note in the bass playing while the rest and eighth notes play from the treble staff?

Make it longer. Specify its duration right after it.

Or use L to change duration: Play “L1C,L16EGECEGEC”

But wouldn't that just play the half note and then the eighths? I don't think it would play them together. Please correct me if I'm wrong.

Hi Kris01

try this

Code: QB64: [Select]

1. PLAY "cp32ep32g p8 c,e,g p4 l2C,l4E,l4G"

I think to hear a difference among the 3 ways of playing these CEG...

Commas allow simultaneous notes. Please run the example.

I figured it out. If I make the bass run in the background then it sounds like it should. The treble clef runs in the foreground independent of what the bass line is doing.

Hi Kris01,

Sounds like interesting app, I hope you share a sample. Welcome to forum!

Thanks bplus! I've been programming since high school (32 years ago! Yikes!) but I've seen some amazing examples of sample code on this forum!
