Sound Machine is a chord player. It's an instrument meant to be fun and easy to play with a computer keyboard or with a large-sized touch screen device.
Sound Machine functions based on the major scale (all the white keys on the piano, if you're starting from the note C). The C major scale, for example, has 7 notes (Do, Re, Mi, Fa, Sol, La, Si 🎵) and each of them represents a chord that is "relevant" within the scale. That means that any chord you play with Sound Machine will be good to hear. No mistakes :)
On its first version, Sound Machine has three main sections:
To play any sound, simply press the keys from 1 to 8 on your keyboard. Each of them represents one degree of the scale.
The main note tells which note the chords start from. It's the note of the 1st chord, A.K.A. the Tonal Center. To change the tonal center you can simply click on each circle button or press the letter keys on your keyboard, as they were the shape of a tiny piano. Here is the full key map:
| Keyboard key | Note |
|---|---|
| a | C |
| w | C# |
| s | D |
| e | D# |
| d | E |
| f | F |
| t | F# |
| g | G |
| y | G# |
| h | A |
| u | A# |
| j | B |
To make it interesing, Sound Machine has currently 3 instruments that can play the chords simultaneously. Again, just click on each instrument you want to enable/disable or press the keys v, b and n to toggle the Keys, the Bass and the Synth, respectively.
Now that you know how Sound Machine works, you're ready to try it out here :)
