Introducing Philtor by White Horse: A Multiband Filter Playground for Sound Explorers

Philtor by White Horse is a powerful Max for Live device that brings multiband filter sequencing to Ableton Live. With 12 independent filter bands, advanced sequencing features, formant and harmonic modes, and full MIDI control, it’s designed for deep, movement-based sound design. Perfect for ambient, experimental, and cinematic audio production.

If you’re looking to add motion, depth, and texture to your sound design, Philtor by White Horse is the tool you’ve been waiting for. Available exclusively from Isotonik Studios, Philtor is a Max for Live device that takes filtering into bold, creative territory. With 12 filter bands, sequencer control, formant and harmonic shaping, and MIDI interaction, it’s built for artists who want to push sonic boundaries.

What Is Philtor?

Philtor is a multiband filter sequencer designed for Ableton Live. Whether you’re sculpting ambient soundscapes, designing rhythmic pulses, or creating experimental audio textures, Philtor gives you the tools to explore sound in motion.

Key Features of Philtor

12 Independent Filter Banks

• Toggle each filter band on or off
• Adjust volume, Q size (resonance), slope, and curve
• Choose between fixed and variable filter modes for maximum flexibility

Built-in Step Sequencer

• One measure of 16 steps, synced to your project
• Control over:
  • Attack: How quickly each filter step ramps in
  • Decay: How long it holds before fading
  • Duration: Overall length of each step (can be extended or shortened)
  • Random Trigger: Introduces variation by triggering random filter bands
  • Random Velocity: Adds dynamic variation for a more organic feel

Stereo Imaging and Saturation

• Stereo/Mono control to spatially position filter steps across the stereo field
• Drive section with:
  • Saturation for added warmth and grit
  • Pull to control intensity
  • Tone to brighten or darken the sound

Formant Filter Sequencing

• Layer valve-like formant sounds using harmonic, subharmonic, or interlaced modes
• Enable sequencing to animate formant transitions over time
• Fine-tune the behavior with controls like:
  • F Slide: Controls how stepped the changes sound
  • Stretch: Adjusts the spread of frequencies across filter bands

Harmonic Sound Generation

• Generate 12 filter bands based on harmonic or subharmonic series
• Select the pitch center (e.g., C3) and control the harmonic skew
• Activate sequencing to move dynamically through the harmonic series
• Ideal for creating rich, evolving overtones and ambient textures

MIDI Control Mode

• Disable the internal sequencer and trigger filter banks via MIDI clips or controllers
• Great for live performance or hands-on modulation
• Offers expressive, instrument-like control over the filtering process

Built for Experimental Sound Design

Philtor isn’t just a filter—it’s a creative tool for designing motion and expression in your music. Perfect for:

• Ambient and textural soundscapes
• Cinematic and game audio design
• Modular-style rhythmic sequencing
• Live performance and improvisation

Whether you’re building swelling drones, granular pulses, or formant-rich FX, Philtor gives you the tools to make your ideas come alive.
