25+ Effects Suite

WAV Recording

Capture your performances with all effects applied and save as high-quality audio.

Understanding the Attack Envelope

What is Attack Time?

Attack time controls how quickly a note reaches its maximum volume after you press a key.

Attack 0ms → Instant sound (plucked string)
Attack 400ms → Gradual swell (bowed feel)
Attack 800ms → Very slow bloom (pad-like)

0ms (Default): Traditional plucked guitar sound - immediate attack like a real classical guitar.
200-400ms: Creates a swelling, violin-like expression - perfect for emotional melodies.
500-800ms: Produces ambient, pad-like textures - ideal for atmospheric music.

Try This Example

Set Attack Time to 350ms and play a slow, simple melody like "Romance Anónimo". The notes will gently swell into each other, creating a beautiful, expressive legato effect that sounds like a bowed instrument!

The Complete Sound Formula

How Your Sound is Created

Final Sound = (Guitar Sample × Attack Envelope) + (Effects Processing) + (EQ Shaping)

Each note you play goes through this complete processing chain in real-time!

Getting Started: Quick Start Guide

1. Playing the Virtual Guitar

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 key shows its corresponding computer key!

Keyboard Layout Guide

White Keys: A, S, D, F, G, H, J, K, L, ;, ', Enter, Z, X, C, V, B, N, M, ,, ., /
Black Keys: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, -, =, F1-F12
Sustain Pedal: Press the SPACEBAR to toggle sustain on/off

2. Understanding the Core Controls

ControlRangeWhat It DoesGuitar Example
Volume0-100%Overall loudness82% = comfortable listening level
Pitch Shift-12 to +12Shifts all notes up/down (semitones)+2 = sounds like tuning up a full step
Playback Speed0.5x to 2.0xChanges note duration0.75x = deeper, longer notes
Attack Time0-800msHow fast sound reaches full volume300ms = soft, swelling attack
Transpose-12 to +12Changes key without changing finger position+5 = play in a different key easily

Real-World Example: Creating Flamenco Style

Settings: Attack 20ms, Reverb mix 45%, Delay 300ms
Result: Creates a bright, percussive flamenco sound with authentic hall ambiance. Perfect for playing bulerías or alegrías!

The Effects Suite Explained

The GDP-500 comes with 3 core effects (with more in the master suite):

🌊 REVERB - Adds space and depth (like playing in a concert hall)
⏱️ DELAY - Creates rhythmic echoes
🎵 CHORUS - Makes it sound like multiple guitars playing together

Signature Classical Guitar Preset

Intimate Salon Sound: Reverb mix 35% + Delay mix 22% + Attack 150ms
This combination creates a warm, intimate sound perfect for classical repertoire like Bach's Cello Suites or Spanish romances.

3. The 10-Band Equalizer (EQ)

The EQ lets you sculpt your guitar's tone by boosting or cutting specific frequencies:

FrequencyWhat It ControlsClassical Guitar Effect
31-125 HzLow BassAdds body and warmth
250-500 HzLower MidsControls fullness/"boxiness"
1k-4k HzMidrangeAffects presence and clarity
8k-16k HzTrebleAdds sparkle and "air"

EQ Tip for Classical Guitar

Boost 500Hz (+2dB) and 1kHz (+3dB) for better note definition. Cut 250Hz (-2dB) to reduce muddiness. Boost 8kHz (+2dB) for added brilliance!

Recording Your Classical Guitar Performances

4. Using the WAV Recorder

The built-in recorder captures everything - your playing, attack envelope, effects, and EQ settings!

  • [ RECORD ] - Start recording (button turns red with pulse animation)
  • [ STOP ] - Stop recording (same button)
  • [ PLAY ] - Listen to your performance
  • [ SAVE ] - Download as high-quality WAV file

Complete Recording Workflow

Step 1: Set Attack Time to desired value (e.g., 200ms for expressive phrasing)
Step 2: Dial in your effects (try Reverb 40% + Delay 25%)
Step 3: Click [RECORD] (button turns red)
Step 4: Play your piece - all dynamics and phrasing are captured
Step 5: Click [STOP], then [PLAY] to review
Step 6: Click [SAVE] to export your masterpiece as WAV

5. Sustain Pedal & Expression

The sustain pedal (🦶 SUSTAIN) lets notes ring after you release the key. This is essential for:

  • Creating smooth, connected phrases (legato)
  • Playing arpeggios where notes blend together
  • Adding emotional depth to slow passages

Pro Technique: Using Attack with Sustain

Set Attack to 250ms and turn Sustain ON. Play a slow chord progression - the notes will bloom gradually and ring together, creating a beautiful, orchestral pad effect perfect for ambient or new-age music!

15 Frequently Asked Questions

1. What makes this different from a regular piano or keyboard?

This is specifically designed for classical guitar! It uses actual nylon-string guitar samples and features an Attack Envelope that shapes how notes bloom - something crucial for realistic guitar expression that pianos don't have.

2. Why can't I hear any sound when I press keys?

Most browsers require a "user gesture" to enable audio. Simply click anywhere on the page or press any key to activate sound. Also check that your device volume is turned up and not muted.

3. What is Attack Time and how do I use it?

Attack Time (0-800ms) controls how quickly a note reaches full volume. 0ms = instant pluck (traditional guitar), 200-400ms = swelling violin-like expression, 500-800ms = ambient pad textures. Use the slider to experiment!

4. Can I use this on my phone or tablet?

Absolutely! The virtual guitar is fully touch-responsive. Tap any key to play, and the interface adjusts for smaller screens. You can also use pinch-to-zoom to see all 61 keys.

5. What's the difference between Pitch Shift and Transpose?

Pitch Shift changes the pitch of the audio sample itself (like speeding up a tape). Transpose shifts which note you hear when you press a key - it's like changing the key of the instrument without affecting sound quality.

6. How do I reset all settings to default?

Each control has its own Reset button (⟳). For a complete reset, refresh the page and click anywhere to re-enable audio. All effects and EQ can also be reset individually.

7. Can I use a MIDI keyboard with this?

Currently, the instrument supports mouse/touch and computer keyboard input. MIDI support is planned for a future update!

8. How does the Attack Envelope affect different playing styles?

Low attack (0-50ms) gives percussive, articulate playing - perfect for flamenco or fast passages. Medium attack (150-300ms) creates expressive, singing phrases ideal for romantic pieces. High attack (400-800ms) produces ambient, swelling pads great for cinematic music.

9. Can I save my effect presets?

Preset saving is coming soon! For now, take screenshots of your settings or use the WAV recorder to capture your performances with your custom settings.

10. What's the maximum recording length?

The recorder can capture up to several minutes depending on your browser's memory. For best results, keep recordings under 5 minutes.

11. Why does the sound sometimes crackle or pop?

This can happen when playing many notes simultaneously or using CPU-intensive effects. Try reducing the number of active effects, lowering the polyphony, or closing other browser tabs.

12. Can I play chords (multiple notes at once)?

Yes! The instrument supports polyphony - you can play up to 8-12 notes simultaneously. Hold down multiple keys to play chords, arpeggios, or full guitar strums!

13. How do I know which computer key plays which note?

Each virtual key shows its corresponding computer key in a small label. White keys use letters (A,S,D,F,G,H,J,K,L...), black keys use numbers (1,2,3...) and function keys (F1,F2...).

14. Is this really free to use?

Absolutely! The Classical Guitar Studio is completely free - no signup, no credit card, no hidden costs. Just open and play!

15. Can I use my recordings commercially?

Yes! All music you create is yours to use however you like - for YouTube videos, albums, commercials, film scoring, or any other project. No royalties or credits required!
