Understanding Attack Envelope: The Heart of Expression
Attack Envelope Formula
This simple formula controls how quickly your note reaches full volume after pressing a key.
Attack time is how long it takes for a note to reach its full volume after you press the key. Think of it like a dimmer switch for sound:
Attack Examples
- 0 ms (Zero Attack): Sharp, percussive sound like a harpsichord or staccato piano. Notes start instantly.
- 200 ms (Soft Attack): Gentle, rounded sound like a soft piano ballad. Notes bloom into existence.
- 500 ms (Slow Attack): Pad-like sound, almost like a string ensemble. Great for ambient music.
- 800 ms (Very Slow Attack): Ethereal, swelling sounds perfect for cinematic builds.
Pro Tip: Expressive Playing
Try setting Attack to 150ms for slow, emotional melodies. For fast classical pieces like Mozart or Beethoven, keep Attack at 0ms for crisp articulation. For ambient or cinematic music, try 400-600ms!
Getting Started: Your First Session
1. Playing the Virtual Grand Piano
You have two ways to play:
- Click or Touch: Simply click on any key with your mouse, or tap on touchscreen devices.
- Computer Keyboard: Use your PC keyboard - each virtual key shows its corresponding computer key!
Try This Now
Press the 'Q' key on your keyboard - you'll hear Middle C. Press 'W' for D, 'E' for E, and so on. The white keys use letters (A,S,D,F,G,H,J,K,L) and black keys use numbers (1,2,3,4...).
2. Keyboard Layout Reference
| Row | Keys (White Keys) | Keys (Black Keys) |
|---|---|---|
| Top Row | Q W E R T Y U I O P [ ] \ | F1-F12, 1 2 3 4 5 6 7 8 9 0 - = |
| Middle Row | A S D F G H J K L ; ' | Located between white keys |
| Bottom Row | Z X C V B N M , . / | Located between white keys |
3. Core Controls Explained
🔊 VOLUME (0-100%) - Controls overall loudness. Start at 85% for comfortable listening.
🎵 PITCH SHIFT (-12 to +12) - Changes pitch in semitones. +1 shifts everything up one half-step (like a capo).
⚡ PLAYBACK SPEED (0.5x to 2.0x) - Changes playback speed. Lower speeds = deeper sound, higher speeds = brighter sound.
🎹 ATTACK TIME (0-800ms) - Controls how quickly notes reach full volume. Lower = sharper, Higher = softer bloom.
Real-World Example
Set Attack to 300ms and Reverb to 40%. Play a slow, simple melody - it will sound like a piano in a large concert hall with a gentle, swelling quality!
4. Using the Transpose Feature
Transpose shifts all notes up or down without changing your finger position. This is incredibly useful for:
- Playing songs in different keys without learning new fingerings
- Matching the pitch of other instruments or singers
- Simplifying difficult key signatures
Transpose Formula
Heard Pitch = Played Pitch + Transpose Value
Example: Press Middle C (C4) with Transpose = +2. You'll actually hear D4!

Ambient Pad: Reverb 60% + Chorus 35% + Attack 600ms
5. The 10-Band Equalizer (EQ)
The EQ lets you boost or cut specific frequency ranges. Think of it as a sophisticated tone control:
| Frequency | What It Controls | Boost Effect |
|---|---|---|
| 31-125 Hz | Bass / Low end | More warmth and body |
| 250-500 Hz | Lower mids | More fullness |
| 1k-4k Hz | Midrange | More presence and clarity |
| 8k-16k Hz | Treble / High end | More brightness and air |
EQ Tips for Grand Piano
Boost 125Hz slightly (+2dB) for more body. Boost 2kHz (+3dB) for clarity and attack. Boost 8kHz (+2dB) for sparkle. Cut 400Hz (-2dB) if the sound is too "boxy".
