Getting Started: A Simple Guide
1. Playing the Virtual Oboe
You have two ways to play the GDP-500 INFINITE FX:
- Click or Touch: Simply click on any key with your mouse, or tap on touchscreen devices.
- Computer Keyboard: Use your PC keyboard - each key is labeled with its corresponding computer key!
Try This Example
Press the 'Q' key on your keyboard - you'll hear the first note (C). Press 'W' for the next note (D), and so on. The keys are arranged like a real piano keyboard!
2. Understanding the Keyboard Layout
The white keys on your computer keyboard are arranged in two rows:
| Row 1 (Top) | Keys |
|---|---|
| First Octave | Tab Q W E R T Y U I O P [ ] \ |
| Second Octave | A S D F G H J K L ; ' Enter |
| Third Octave | Z X C V B N M , . / |
Pro Tip
Look at the labels on each virtual key - they show you which computer key to press. Black keys use number keys (1,2,3...) and function keys (F1, F2...).
Understanding the Sound Formula
How Your Sound is Created
Each note you play goes through this processing chain in real-time!
3. Mastering the Controls
🎚️ Volume (0-100%) - Controls how loud the instrument sounds. Start at 80% for comfortable listening.
🎵 Pitch Shift (-12 to +12 semitones) - Changes the pitch of all notes. Use +1 to shift up one half-step (like using a capo on guitar).
⚡ Playback Speed (0.5x to 2.0x) - Changes how fast the sound plays. Lower speeds create deeper, longer sounds; higher speeds create brighter, shorter sounds.
Real-World Example
Set Pitch Shift to +5 and Speed to 0.75x. Play a simple melody - it will sound like a deeper, warmer oboe! Perfect for creating atmospheric background music.
4. Using the Transpose Feature
Transpose lets you shift 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
- Simplifying difficult key signatures
Transpose Formula
New Pitch = Original Pitch + Transpose Value
Example: If you press the C key (note C) and Transpose is +2, you'll actually hear a D note!
The Effects Suite Explained
The GDP-500 comes with over 25 professional audio effects. Here's what each one does:
Create Your First Effect Chain
Try this combination: Turn on Reverb (mix 40%) + Delay (mix 30%, time 300ms) + Chorus (mix 35%). Play a slow melody - it will sound like you're in a cathedral with a choir of oboes!
5. The 10-Band Equalizer (EQ)
The EQ lets you boost or cut specific frequency ranges. Think of it as a tone control with 10 different knobs!
| 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 Tip for Oboe
Boost 500Hz and 1kHz slightly (+3dB) to make the oboe cut through other instruments. Boost 8kHz (+2dB) for extra sparkle!

61 keys (5 octaves) is the standard range for most portable keyboards and synthesizers. It covers the full range of the oboe and most popular music, while keeping the interface manageable.
Effects are processed in series (one after another). The order is: Reverb → Delay → EQ → Volume. Each effect processes the sound from the previous effect.
Preset saving is coming in a future update. For now, take screenshots of your settings or use the WAV recorder to capture your performances.
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 or closing other browser tabs to free up processing power.
