What is Attack Envelope? (The Secret to Expressive Playing)
Attack Envelope Explained
Attack Time controls how quickly a note reaches its full volume after you press the key.
Attack Envelope Formula
At 0ms: Sound starts instantly. At 800ms: Takes 0.8 seconds to reach full volume.
Try This Example
Step 1: Set Attack Time to 0ms and play a chord - you'll hear a sharp, percussive attack like a classical piano.
Step 2: Increase Attack Time to 400ms and play the same chord - notice how the sound slowly blooms into existence!
Step 3: Try 600ms with reverb enabled for an ambient, cinematic pad sound.
Understanding the Sound Processing Chain
Complete Sound Formula
Each note you play goes through this entire processing chain in real-time!
Getting Started: Quick Guide
1. Playing the Piano
You have two ways to play:
- Click or Touch: Tap any key with your mouse or finger on touchscreens
- Computer Keyboard: Use your PC keyboard - each virtual key shows its corresponding computer key!
| Row | Keys (White Keys) | Keys (Black Keys) |
|---|---|---|
| Top Row | Tab Q W E R T Y U I O P [ ] \ | F1 F2 F3 F4 F5 F6 F7 F8 F9 F10 F11 F12 |
| Middle Row | A S D F G H J K L ; ' Enter | 1 2 3 4 5 6 7 8 9 0 - = |
| Bottom Row | Z X C V B N M , . / | Backspace (Delete) |
Pro Tip: Spacebar Sustain
Press the SPACEBAR to activate the sustain pedal! Notes will continue ringing even after you release the keys - perfect for creating connected, flowing phrases.
2. Core Controls Explained
🔊 VOLUME (0-100%) - Controls overall loudness. Start at 85% for comfortable listening.
🎵 PITCH SHIFT (-12 to +12 semitones) - Changes the pitch of all notes. +12 = one full octave higher! Great for transposing songs to different keys.
⚡ PLAYBACK SPEED (0.5x to 2.0x) - Changes playback speed. Lower speeds create deeper, longer sounds (like slowing down a tape).
🎹 ATTACK TIME (0-800ms) - Our signature feature! Controls how quickly notes reach full volume.
Real-World Example: Creating a Cinematic Pad
Settings to try:
• Attack Time: 600ms
• Reverb: ON (mix 50%)
• Delay: ON (mix 25%, time 400ms)
• Play a slow chord progression - you'll create an atmospheric, cinematic pad perfect for film scoring!
3. Transpose Feature
Transpose shifts all notes up or down without changing your finger positions. This is incredibly useful for:
- Playing songs in different keys without learning new fingerings
- Matching the pitch of other instruments or recordings
- Simplifying difficult key signatures
Transpose Formula
Output Pitch = Original Pitch + Transpose Value
Example: Press the C key with Transpose = +5, you'll hear an F note!
The Complete Effects Suite
The Grand Piano comes with 3 core studio effects that can transform your sound dramatically:
4. 10-Band Equalizer (EQ)
The EQ lets you boost or cut specific frequency ranges to shape your tone:
| Frequency | What It Controls | Boost Effect |
|---|---|---|
| 31-125 Hz | Bass / Low end | More warmth and body (great for left hand) |
| 250-500 Hz | Lower mids | More fullness and power |
| 1k-4k Hz | Midrange | More presence and clarity (makes piano cut through) |
| 8k-16k Hz | Treble / High end | More brightness and sparkle (adds "air") |
EQ Preset for Classical Piano
Boost 500Hz (+3dB) for warmth, boost 2kHz (+2dB) for clarity, slightly reduce 8kHz (-2dB) to soften harshness. This creates a rich, concert hall piano sound!
Recording Your Music
5. Using the WAV Recorder
The built-in recorder captures everything - your playing, all effects, attack envelope settings, and EQ!
- [ RECORD ] - Click to start recording (button turns red)
- [ STOP ] - Click the same button to stop recording
- [ PLAY ] - Listen to your recorded performance
- [ SAVE ] - Download as a WAV file for sharing or production
Complete Recording Workflow
1. Set your Attack Time and Effects
2. Click [RECORD] (button turns red)
3. Play your piece - all notes are captured with timing
4. Click [STOP] when finished
5. Click [PLAY] to review your performance
6. Click [SAVE] to export as WAV file
6. Sustain Pedal
The sustain pedal (🦶 SUSTAIN) makes notes continue ringing after you release keys. This is essential for:
- Creating smooth, connected phrases (legato playing)
- Making chords ring together harmoniously
- Adding emotional, cinematic feel to slow passages
Note About Attack Time + Sustain
When using long attack times (400ms+), the sustain pedal will keep the note ringing through its attack phase. This can create beautiful, evolving pads. Experiment with different combinations!
15 Frequently Asked Questions
Attack Envelope lets you shape the initial moment of each note - from sharp, percussive attacks (0ms) to soft, swelling entrances (800ms). This is usually only found on synthesizers, but we've added it to the grand piano for expressive control!
Most browsers require a "user gesture" to enable audio. Simply click anywhere on the page or press any key to activate sound. Also check your device volume and that samples have loaded (look for "Ready: 61/61" in stats).
Yes! The Grand Piano is fully touch-responsive. Tap any key to play, and use pinch-to-zoom to navigate the 61-key keyboard. The interface automatically adjusts for smaller screens.
Attack Time controls how quickly a note reaches full volume after you press the key. Sustain keeps notes ringing after you release the key. They work together - long attack + sustain = beautiful swelling pads!
Click the ⟳ RESET button next to each control. For a complete reset, refresh the page and click anywhere to re-enable audio. All effects and EQ will return to default.
Currently, the Grand Piano supports mouse/touch and computer keyboard input. MIDI support is planned for a future update. The computer keyboard mapping gives you 61 keys to play with!
61 keys (5 octaves) is the standard range for most professional keyboards and covers 95% of all piano music. It's also the optimal size for computer keyboard mapping and mobile screens.
Each EQ band controls a specific frequency range. Moving a slider up (+12dB) boosts that frequency, moving down (-12dB) cuts it. Use this to fix problematic frequencies or enhance desirable ones in your piano sound.
Preset saving is coming in a future update. For now, use the WAV recorder to capture your performances, or take screenshots of your favorite settings.
The recorder can capture performances up to several minutes long, depending on your browser's memory. For best results, keep recordings under 5 minutes.
This can happen if you're playing many notes at once or using CPU-intensive effects. Try reducing the number of active effects, closing other browser tabs, or lowering the volume slightly to prevent digital clipping.
Yes! The Grand Piano supports polyphony - you can play up to 8-12 notes simultaneously. Hold down multiple keys to play rich chords and complex harmonies!
Each virtual key shows its corresponding computer key in a small label. White keys use letters (Q,W,E,R,T,Y...), black keys use numbers (1,2,3...) and function keys (F1,F2...). Look at the key labels!
