# Keyboard
***
### Overview
EPROM Memory Rites keyboard area contains essential performance and musical controls for scale-locking presets and more. On the left, you'll find expressive controls including global preset rate, pitch bend, and the mod wheel for shaping your performance in real time.
On the right, creative tools such as the Arpeggiator and Scale Settings help generate musical ideas while keeping everything locked to your project's key and scale.

### 1. Rate
Sets the speed of the plugin internal tempo. Higher values increase the rate of tempo-synced processes, such as the internal modulation and arpeggiator, while lower values create slower rhythmic patterns.
### 2. Pitch Bend
Is a control used to temporarily raise or lower the pitch of a note, allowing for expressive performance techniques such as bends, slides, and vibrato. Above the Pitch Bend wheel is the adjustable pitch bend range in semitones.
### 3. Mod Wheel
Use the mod wheel for expressive real-time adjustments on thematic parameters. All presets include internal mod wheel assignments.
### 4. Scale
Define the root note and scale to keep all generated notes in key when the Arpeggiator or Chord generator are active.
Use the lock button to ensure your selected scale is preserved when changing presets.
### 5. Arpeggiator
Some presets include an internal arpeggiator that converts held chords into rhythmic note patterns. Active arpeggiation will be indicated here.
