Saxophone Piano →What Makes the GDP-500 INFINITE FX Special?
Most digital pianos give you basic sound and maybe a few effects. The GDP-500 INFINITE FX is different. It's built from the ground up to give you complete control over your sound, from the moment a note begins to its final decay.
61-Key Concert Grand
Authentic grand piano samples from a world-class concert grand, meticulously recorded and mapped across 61 keys.
Attack Envelope Control (0-800ms)
Shape the very beginning of every note — from soft, blooming attacks to sharp, percussive articulations.
25+ Effects Suite
Reverb, delay, chorus, pitch shift, and more — all adjustable in real-time with professional-grade algorithms.
10-Band Graphic Equalizer
Precision EQ from 31Hz to 16kHz — shape your tone like a studio engineer.
Understanding Attack Envelope: The Secret to Expressive Playing
0ms = Instant attack (percussive) · 800ms = Slow bloom (soft, swelling)
The Attack Envelope controls how quickly a note reaches its full volume after you press a key. This is one of the most important aspects of piano playing that digital instruments often get wrong.
🎵 Attack Time Examples:
- 0-50ms (Fast Attack): Perfect for staccato, jazz, and percussive classical pieces. Every note is crisp and defined.
- 100-300ms (Medium Attack): Balanced attack for general playing — works for most musical styles.
- 400-800ms (Slow Attack): Creates a soft, swelling effect ideal for ambient music, ballads, and cinematic scores.
💡 Pro Tip: Attack and Expression
Try increasing the attack time for slower, emotional pieces. The slight delay before the full note blooms creates a beautiful, vocal-like quality that draws listeners in.
The Complete Effects Suite (25+ Modules)
The GDP-500 INFINITE FX includes a professional-grade effects processor that would cost thousands as a standalone unit. Here's what you can do:
| Effect Category | Parameters | Best For |
|---|---|---|
| 🌊 Reverb | Mix (0-100%), Decay (0.5-5s) | Concert halls, cathedrals, intimate rooms |
| ⏱️ Delay | Mix, Time (50-500ms), Feedback (0-80%) | Echo effects, rhythmic patterns, dub |
| 🎵 Chorus | Mix, Rate (0.5-8Hz), Depth | Thickening, widening, ensemble effects |
| 🎚️ 10-Band EQ | ±12dB per band (31Hz-16kHz) | Tone shaping, removing muddiness, adding sparkle |
| ⚡ Pitch Shift | -12 to +12 semitones | Transposition, creative effects |
| 🔊 Volume & Speed | Volume 0-100%, Speed 0.5x-2.0x | Dynamic control, practice modes |
The 10-Band Equalizer Explained
Equalization is the art of balancing frequencies. Our 10-band EQ gives you surgical precision over your piano's tone:
- 31-125Hz (Sub-bass to Bass): Controls the "weight" and "warmth" of low notes
- 250-500Hz (Low-mids): Where "muddy" sounds live — cut here for clarity
- 1-2kHz (Mids): The "presence" zone — boost for more attack
- 4-8kHz (High-mids): Adds "bite" and definition
- 16kHz (Treble): Adds "air" and sparkle
🎚️ Quick EQ Presets:
- Bright Concert Tone: Boost 4kHz +3dB, 8kHz +2dB, cut 250Hz -2dB
- Warm Jazz Sound: Boost 125Hz +2dB, cut 2kHz -1dB
- Cinematic Pad: Boost 63Hz +4dB, cut 500Hz -3dB, boost 16kHz +2dB
Transposition: Play in Any Key
The built-in transposition feature lets you shift the entire keyboard up or down by up to 12 semitones (one full octave). This is incredibly useful for:
- Singers: Play in a comfortable key while accompanying vocalists
- Learning: Practice pieces in different keys without relearning fingerings
- Composition: Explore harmonic possibilities quickly
- Live Performance: Adapt to any key on the fly
🎼 Transposition Tip
Try transposing down 2 semitones and playing a song you know in C major — you'll be playing in Bb major automatically! Great for accompanying horn players.

The Science Behind Attack Envelope
The GDP-500 INFINITE FX focuses on the Attack phase — the most expressive part of any note
In acoustic piano playing, the attack is controlled entirely by finger velocity and technique. Our digital implementation gives you precise control over this crucial parameter, opening up expressive possibilities that even acoustic pianos can't match.
Why Musicians Love the GDP-500 INFINITE FX
- Studio Producers: "The attack control alone is worth the price. I can shape piano sounds for any genre."
- Classical Pianists: "Finally, a digital piano that responds like a real instrument. The nuance is incredible."
- Film Composers: "The effects suite means I can create cinematic textures without leaving my DAW."
- Music Teachers: "My students love the visual feedback and the ability to experiment with different sounds."
