Introduction

This silly plugin attempts to create procedural music based on music theory.

The pianola creates a song for itself, with varying length, scale, key, chords and fullness. When it's done playing its song it will make a new one. And a new one. Forever.

Maybe use it for the piano player at the inn, for ambient adventure music or a haunted piano?

It's entirely a sound plugin but why not show it off with a piano dance:




How to use
To make a pianola you need a parallel event.

Step 1: Add a Wait to the event, this adjusts the tempo of the pianola.
The Wait defines how long a quarter note should be.
So Wait set to 30 roughly translates to 120 bpm (allegro moderato), a very popular tempo.

The longer the Wait the slower the music. If you're unsure, set Wait to 30.
Without a Wait it will be a confused, cloudy and loud ooze of sound.

Step 2: Use script call and enter pianola()
That's it! The event will now play the piano!

Bonus: You can define a max volume, for example 50, like this: pianola(50)
