Settings

This button in the toolbar allows you to access scene settings and general settings for Acccelerando.

The settings window has two parts: sound and settings.

Sound

Here you can adjust basic sound settings for the scene, e.g. volume of different sound sources, drums, rhythm and chord progression. These settings are saved with the scene.

Volume

These volume settings should be self-explanatory. You can change settings for instrument sounds and the background synthesizer (see: Editing Instruments) or turn a sound source on or off.

Drums

Acccelerando includes a small, simple drum set. You can turn it on or off or adjust the volume.

For sound, you can choose between electronic and acoustic drums on the left.

With the selection box on the right, you can choose a rhythm. Several premade rhythms are available, including a simple metronome.

Tempo

The tempo of the scene (the speed at which notes are created and played) can be chosen in beats per minute from a predefined list.

The checkbox "Shuffle rhythm" plays every fourth sixteenth note in a rhythm as a triplet. Try it out and see if you enjoy the "swing" it adds to the scene. It depends on your scene - it can sound rather clumsy sometimes.

Chord progression

To make an Acccelerando scene sound a bit more lively and melodic, you can choose a chord progression here.

A chord sequence shifts (transposes) the notes by a certain value for each measure. The different pitches or degrees are described with Roman numerals. I is the basic degree (tonic) where the tones are not transposed. V indicates that the tone is played four white keys higher, on the fifth degree (the dominant in musical terms) In this example, a C note played at V becomes a G, and an A becomes an E.

This will sound rather complex to non-musicians, so my advice is: just try it out! If the notes of a scene are roughly oriented towards the tones of the A minor or C major chords, it'll usually work pretty well.

Several chord progressions are available that you may be familiar with.

If a chord progression has been selected, a small colored bar is displayed at the bottom of the scene. It indicates the current degree of the scene.

Settings

In the Settings area within Settings (sounds funny, I know), you can change display options for the current scene and general settings for the app.

Current scene

If you like, you can make bursting notes paint the background of the scene with colorful splotches ("pixel art").

A note area surrounds flying notes of an instrument with a translucent shape.

You can also display a connection line between a note and the instrument it came from.

These settings are saved with the scene.

The purely informational FPS (frames per second) display on the right shows at what frame rate the scene is currently being displayed. 25 FPS are an optimum value to aim for. If the number is significantly lower than that, you should consider using a little less of everything (instruments, notes, display options), as your device can't handle any more. But you can also just choose to ignore the stuttering.

General settings

The most interesting option here is background color. The setting "bright" can be handy sometimes when you're sitting in bright sunlight and can't see the dark colors of the "dark" setting. But it's also just a matter of taste.

Change the audio quality setting if you want better sound. However, depending on your device, this may cause skipping or crackling.
