Avi Bortnick has released EchoSketch, available for $4.99.
Delay effects are often treated as static processing tools—set a millisecond time, adjust feedback, mix it in, and leave it alone. However, EchoSketch: Performance Delay redesigns the delay engine around dynamic performance, transforming spatial audio into a touch-responsive instrument.
Rather than focusing on sub-menus or precise rotary knobs during live sets, EchoSketch uses a touch-first X/Y performance surface.
You can map multiple effect parameters simultaneously to the X and Y axes, setting custom minimum and maximum ranges for each. Dragging a finger across the pad allows you to morph seamlessly between subtle echo washes and pitch-gliding, feedback-heavy textures.
Whether you are performing live electronic sets, processing ambient guitars, or adding movement to studio mixes, EchoSketch bridges the gap between static delay effects and expressive real-time sound design.
Features include:
- 4 Distinct Delay Algorithms:
- Digital: Modeled after classic 1980s rackmount units for crisp, rhythmic repeats.
- Analog: Warm, bucket-brigade style delays featuring tape-like pitch gliding when time settings change.
- Ping-Pong: Alternating left/right spatial bouncing.
- Reverse: Backward delay repeats ideal for ambient swells and psych-rock textures.
- Independent Convolution Reverb: Offers Spring, Plate, and Hall IRs. Crucially, the reverb engine runs parallel to the delay path (resembling vintage tape echo units), preventing repeats from turning into a muddy wash.
- Dynamic Tone & Modulation: Warm or brighten repeats with a dedicated tone filter, or introduce analog-style chorus pitch warble.
