Creative Modulation with 2hp Delay: Unique Sound Design

The 2hp Delay module is a compact, CV-controllable digital delay suited for everything from crispy percussive effects to deep, warping pads. Here are high-impact modulation strategies for distorted percussion, dubstep/drum & bass basslines, and haunting pads:

1. Distorted Percussive Sounds

• Key Modulations: FDBK CV, TIME CV
• Process:
• Patch drums or short percussive sounds (e.g., from a drum module or synth voice) into the IN.
• Set TIME low (short delay times = slapback) for glitchy artifacts.
• Modulate TIME CV from a fast envelope or trigger sequencer, making each hit shift in delay time—this introduces accents, pitch artifacts, and off-kilter pulses.
• Increase FDBK, perhaps modulated with random stepped CV (Sample & Hold, random gates, or even audio-rate CV) to push the repeats into self-oscillation for overdriven, crushed sound.
• Option: Overdrive by pushing the FDBK knob to maximum, allowing chaotic feedback loops—a classic distorted, noisy percussion trick.
• Mix: Use MIX CV to dynamically blend dry/wet sound with accent envelopes.

2. Dubstep/Drum & Bass Basslines

• Key Modulations: TIME CV, FDBK CV, MIX CV
• Process:
• Patch bass synth voice to IN.
• Use LFOs or Envelopes to modulate TIME CV between 0V and 5V on the beat. Extreme modulation can cause pitch-smearing and aggressive time-stretched bass movement typical in Neuro, brostep, or techstep.
• Set FDBK high and modulate with another LFO or envelope—increasing feedback during drops and breakdowns for growling, resonant tails.
• Audio-rate modulation to TIME CV or FDBK CV (patch fast LFO or even oscillator) can create FM-like distortion and unexpected bass artifacts.
• Automate MIX CV with sequencer or envelope—bring the delay in and out with quick movements for dramatic, rhythmic variation.

3. Haunting Atmospheric Pads

• Key Modulations: TIME CV, FDBK CV, MIX CV
• Process:
• Patch drones, chords, or evolving pads to IN.
• Set TIME to longer settings (fully clockwise) for almost 2 seconds of repetition.
• Use slow, subtle LFO or random voltage to modulate TIME CV—this creates gentle pitch modulation and evolving, ghostly motion as repeats smear and shift.
• Push FDBK close to maximum (just before infinite self-oscillation) and gently modulate with slow envelopes/random CV for shimmering echoes and swelling noise layers.
• Set MIX to about 50/50 and automate with slow envelopes or a joystick to pan between dry and wet, moving through blurry, mysterious spaces.
• Bonus: Patch the OUT back into FX or another delay for deep, atmospheric layering.

Additional Patch Tips

• CV inputs are all added to the knob positions (0–5V), so hands-on tweaks plus automation can be combined.
• Use end-of-cycle triggers or rhythm clocks to periodically drive extreme FDBK or TIME jumps for automated fills/breaks.
• Clocked stepped random (Sample & Hold) into TIME or FDBK CV makes granular, evolving effects.
