What is Attack Envelope? (Simple Explanation)
How Attack Shapes Your Sound
Attack Time: 0 ms - Instant sound
What is Attack?
Attack is how quickly a sound reaches its full volume when you press a key. Think of it like this:
- 0 ms attack: The sound hits you instantly - like a drum strike or a sharp piano note
- 200 ms attack: The sound fades in gently - like a string section swelling
- 500+ ms attack: The sound blooms slowly - like a cinematic pad or ambient texture
The Attack Envelope Formula
Where t = time after key press, AttackTime = your setting (0-800ms)
At 0ms: Volume jumps to 100% instantly. At 400ms: Takes 0.4 seconds to reach full volume.
Try This Example
Step 1: Set Attack Time to 0 ms - play a key. You'll hear an instant, punchy sound.
Step 2: Set Attack Time to 300 ms - play the same key. Notice how the sound swells in smoothly!
Step 3: Set Attack Time to 600 ms - play a chord. It creates a beautiful, cinematic swell perfect for ambient music.

Pro Tip: Combining Attack and Reverb
Set Attack to 400ms and Reverb mix to 40%. Play slow chords - you'll get a beautiful, swelling pad that feels like a string orchestra. Perfect for film scores and ambient music!
Understanding the Effects Suite
🌊 REVERB
Reverb simulates the natural echoes of a physical space. Higher mix = playing in a cathedral, lower mix = playing in a small room.
⏱️ DELAY
Delay creates repeating echoes of your notes. Think of it like shouting into a canyon - your voice echoes back at regular intervals.
🎵 CHORUS
Chorus makes your piano sound like multiple instruments playing together, creating a rich, thick texture.
10-Band Equalizer (EQ) Guide
The EQ lets you boost or cut specific frequency ranges. Here's what each band controls:
| Frequency | Effect When Boosted | Best For |
|---|---|---|
| 31-63 Hz | More bass rumble and power | Electronic music, bass-heavy tracks |
| 125-250 Hz | More warmth and body | Adding fullness to thin sounds |
| 500-1000 Hz | More presence and punch | Making piano cut through a mix |
| 2000-4000 Hz | More clarity and attack | Adding bite to percussive sounds |
| 8000-16000 Hz | More brightness and air | Adding sparkle and detail |
EQ Preset for Stage Piano
Bright & Punchy: Boost 2kHz (+4dB) and 8kHz (+3dB), slight cut at 250Hz (-2dB)
Warm & Mellow: Boost 125Hz (+3dB), cut 4kHz (-3dB), slight boost at 500Hz (+2dB)
