Vagabond Synth vs DelayScaper
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Vagabond Synth
This is a free wavetable synthesizer app that can be used standalone or as an AUv3 instrument. It offers 16 voice polyphony, multiple oscillators, a switchable filter, modulation, and effects. It also includes a MIDI processor for generating musical sequences.

Vagabond is an idiosyncratic wavetable synthesiser, running standalone or as an AUv3 instrument in compatible hosts such as GarageBand, AUM, Loopy Pro or Cubasis. It features 16 voice polyphony, 4 unison oscillators per voice plus a sub-oscillator, switchable filter, a bit of modulation and some effects. Also built in is a MIDI processor plugin, Twelve, a generative music toy that creates 12-bar blues sequences. Vagabond uses this for demo purposes, but you can load it in other hosts if you like. It's kind of a one trick pony, but one trick is better than none. As always, Vagabond is 100% free, no IAPs, no subs, no spyware, no nag screens. We don't want your money and we don't want your data.
DelayScaper
This audio effects plugin offers dual dynamic stereo delays that respond to input intensity and note spacing. It allows for experimental sound design, atmospheric textures, and even looping, with bonus effects like octave pitch-shifting and random reversing.
- Dual stereo delay modules
- Dynamic parameter response to audio input
- Host tempo syncable delay times
- Max 8-second delay time
- Octave Grains effect
- Random Reverse effect
- Envelope followers for modulation

DelayScaper is an AUv3 effects plugin that can run standalone, or in any AUv3 compatible host such as Logic Pro, GarageBand or AUM. DelayScaper currently runs on iOS (iPad & iPhone) and macOS (Intel & Silicon) and is available as a Universal Purchase from the Apple App Store. Overview DelayScaper is a dual dynamic delay effect designed to produce inspiring, and sometimes very unpredictable results that literally responds dynamically to audio input. Playing an instrument through DelayScaper can be especially rewarding when you adjust your playing to what you’re hearing, because DelayScaper can be configured to constantly modify its parameters according to the intensity and spacing of your notes. It’s like having five extra pairs of hands twiddling knobs for you! At its core, DelayScaper comprises two identical stereo delay modules that can run in series or parallel. While it can cover “normal” delay duties, including host tempo syncable delay times, DelayScaper is really for those who like to experiment with sound, especially in the atmospheric and ambient realm. With a maximum delay time of 8 seconds, you can even use DelayScaper as an old-school “free looper” for “Frippertronics” type evolving soundscapes. DelayScaper also features two bonus “one knob FX” effects that are both original designs that complement the core delay processing: “Octave Grains” is a randomised and delayed pitch-shifting algorithm that sits somewhere between a pitch-shifted delay and granular shimmer effect. “Random Reverse” does what you might expect it to do, but often in an unexpected way! Both algorithms will grab random sections of the incoming audio, process it, then feed those into the main delay processing. The dynamics section is where DelayScaper comes to life, and includes dedicated envelope followers for both delays, which can then be used as a modulation source for up to 5 delay parameters for each delay. For example, you can modulate the mix level to create a “ducking delay”, or modulate tone so the delay repeats get brighter or darker depending on how hard or softly you play. A “cascade” feature sends the output of the first delay into the second, allowing you to fine-tune the balance between parallel and series mode.

Verdict
The clearest difference is price: Vagabond Synth at Free against DelayScaper's $4.99. DelayScaper's advantage is update cadence (daily vs every 3 months) and iOS requirement (12.0 vs 15.0). On rating, review sentiment, ratings volume and ads there is nothing between them.
