A five-effect audio processing bundle from Ear Candy Tech, featuring pitch shifting, hybrid reverb, modulated filtering, sequenced delay, and modulated distortion for creative sound design and mixing.

Bundle Overview
The Gema Bundle from Ear Candy Tech brings together five distinct audio processors, each built around a gemstone-inspired theme. This collection covers pitch shifting, reverb, filtering, delay, and distortion, providing a versatile toolkit for transforming vocals, synths, drums, and full mixes. The five plugins are designed to add depth, movement, color, and rhythmic interest to any source.
Each effect is presented as a standalone device, allowing you to insert them individually on tracks or buses. The bundle is intended for producers and sound designers who want creative, characterful processing beyond standard utilities. While each unit has its own identity, together they form a cohesive set for shaping tone, space, and modulation across a project.
Pitch and Space
Ambar is a three-mode pitch shifter capable of musical transposition, robotic effects, and spectral transformations. Its modes range from Classic, which is musical and warm, to Modern for synthetic textures, and Spectral for harmonic re-synthesis. The main pitch control shifts sounds across a wide range, from deep sub-octaves to shimmering highs, with smooth tracking.
Esmeralda II is a hybrid reverb that combines convolution and algorithmic processing. It offers multiple reverb types and impulse responses, allowing for anything from tight rooms to lush halls and abstract effects. A synthetic mode adds algorithmic shaping on top of the impulse responses, giving you extra control over the reverb tail and character.
Modulation and Rhythm
Obsidian is a modulated filter with a variety of filter types for spectral shaping. It includes modulation sources such as LFOs, envelope followers, fluid-motion simulation, and physics-inspired options. These modulators can drive the filter to create rhythmic pulses, chaotic evolution, or organic movement, making it expressive for adding motion to static sounds.
Ruby II is a delay and tremolo effect with a sixteen-step sequencer for designing echo patterns. Each step can be pitched by semitones for tonal variations, and the tremolo section offers rate and depth controls with multiple waveforms. This makes Ruby II suitable for rhythmic delays, glitchy rolls, and pulsating textures.
Distortion and Applications
Zafiro II is a modulated distortion that ranges from clean boost to fuzz and metallic crunch via its central knob. It includes a built-in LFO with waveforms like sine, triangle, and asymmetry for adding rhythmic or morphing motion to the distortion. This plugin is useful for adding edge, warmth, or aggressive texture to tracks.
In practical use, these effects can be chained or applied individually. For instance, use Obsidian to sweep a pad before sending it to Esmeralda II for space, or apply Ruby II to create rhythmic echoes on a synth line. Zafiro II can add grit to drums, while Ambar can create octave layers or unusual textures. The bundle is best suited for creative music production and sound design.
