Product Review

Product reviewed

Sylenth1 (often mis-heard/auto-labeled as “Silent One”) — an older synth plug-in used for sound design, shown creating a synth pad/bass-style sound with extensive modulation.

Key features mentioned (what it can do)

  • Polyphony control: increase voices to handle dense chords.
  • Oscillator building blocks
    • Waveform selection: sawtooth used; A1/A2 layered.
    • Detune / fine tuning: slight out-of-tune spread for “analog vibes.”
    • Pulse width: used while layering A1 and A2.
    • Noise oscillator: used on Part B for subtle texture.
  • Filter system
    • Low-pass filter with resonance.
    • Filter drive knob for analog-style warmth.
    • LFO modulation of filter cutoff (A/B cutoff).
  • LFO and modulation
    • LFO1 sync modulation of filter cutoff (cutoff A and B) using sync rate and shaped modulation via an envelope.
    • LFO1 waveform change to sawtooth for a transient click.
    • LFO2 in free mode (unsynced) with a random waveform to vary timbre/chords.
    • LFO2 destinations include:
      • phaser frequency
      • panning of oscillators A/B for stereo motion.
  • Built-in effects used in the demo
    • Bit-crush/distortion for lo-fi texture (dry/wet and amount adjusted).
    • Phaser with LFO gain, feedback, width, and additional modulation.
    • Delay (dotted 1/8 and 1/8 mentioned), plus low cut and high cut to keep it low-fi.
    • Reverb with pre-delay, size, width, and re-rip dampening.
  • Ease of use / workflow
    • Emphasis that it has relatively few knobs/sliders, making it “pretty easy to sculpt” sounds.

User experience / sound design workflow notes

  • The creator has owned and used Sylenth1 for ~10 years and still uses it heavily today, especially for bass lines.
  • During sound design, they recommend checking volume meters to avoid clipping/red peaks, reducing main volume if necessary.
  • Even though the plugin is old, it’s described as still having “awesome sounding filters” that are warm.

Pros highlighted

  • Still worth it in 2025 (explicit claim by the video title and closing recommendation).
  • Warm, high-quality filters, especially the filter drive knob.
  • Fast sound shaping due to fewer controls and straightforward architecture.
  • Strong modulation capabilities (LFO envelopes, random/free modulation, stereo panning, cutoff movement).
  • Good for atmospheric pads and melodic/progressive styles (movement suited to progressive/deep house-type tracks).
  • Solid effects integration for lo-fi and movement (bitcrush, phaser, delay, reverb).

Cons / limitations mentioned

  • No direct “this is bad” critique was given.
  • Indirect downside: levels can easily clip (“going in the red”), so you may need to manage output gain carefully.

Comparisons made

  • No direct comparisons to specific plugins (e.g., Serum, Massive, Diva, etc.) were mentioned.
  • The only “comparison-like” remarks are qualitative references to common styles (e.g., progressive house, melodic deep house).

Overall example use (what they built)

  • Start: D# minor chords; initial preset not great.
  • Build a pad using:
    • Multiple voices + saw → detune/spread
    • A1 phasing + amplitude envelope shaping
    • Layer A1/A2 with pulse width and controlled re-trigger behavior
    • Blend in Part B noise subtly
    • LFO-driven filter cutoff movement, then add extra lo-fi/distortion
    • Phaser motion with LFO2 random modulation
    • Stereo panning motion via LFO2
    • Finish with delay + reverb
  • Context: presented alongside prepared drums and a baseline to hear it in a fuller arrangement.

Verdict / recommendation (from the video)

  • The creator recommends trying Sylenth1 and concludes it’s still holding up in 2025, mainly due to:
    • warm filters
    • easy sound design
    • powerful modulation/effects

Unique points mentioned (deduplicated list)

  1. Used for ~10 years; still heavily used today, especially for bass lines.
  2. Demonstrates creating a synth pad with LFO-driven filter modulation.
  3. Increase polyphony/voices for dense chords.
  4. Use sawtooth plus detune for voice spread.
  5. Watch volume meters to avoid clipping.
  6. Add phasing to oscillator A1.
  7. Shape the amplitude envelope with release.
  8. Layer A1/A2 for texture; use pulse width and avoid re-triggering.
  9. Use a low-pass filter with resonance.
  10. Love the filter drive knob for analog warmth; good knob to automate.
  11. Add Part B with a noise oscillator for subtle texture.
  12. Noise filtering and keep noise mix low.
  13. Use LFO1 sync to modulate cutoff A/B.
  14. Use mod envelope 2 to shape LFO behavior for long chord movement.
  15. Find a “sweet spot” for modulation amount (too much can be excessive).
  16. Change LFO1 waveform to saw for a transient click.
  17. Old plugin still sounds warm and “awesome.”
  18. Add bitcrush/distortion for lo-fi texture (dry/wet + amount).
  19. Phaser tweaks: LFO gain, drive/feedback/width adjustments.
  20. LFO2 random waveform in free mode (unsynced) to vary each chord hit.
  21. LFO2 can modulate phaser frequency.
  22. LFO2 also modulates panning of oscillators A/B for stereo motion.
  23. Add delay with 1/8 dotted / 1/8 settings; use low/high cuts for low-fi.
  24. Add reverb with pre-delay (~40 ms), size/width adjustments, and dampening.
  25. Use arrangement context (drums/baseline) to show the final sound.
  26. Concludes with: try it—easy for learning sound design; still worth it in 2025.
