Retro Synthstack brings together 13 distinct analog synth oscillators, featuring iconic sounds from legendary instruments like the Juno-60, Moog, and Prophet. These classic synthesizers are captured in detail, including their unique tonal quirks and irregularities across the entire keyboard, providing an authentic vintage character. The samples were recorded through tube preamps to preserve warmth and depth, offering a rich foundation for music production.

By stacking these 13 oscillators, Retro Synthstack enables the creation of fresh, hybrid sounds that blend the signature qualities of each synth. Whether used individually or combined, these sounds allow producers to craft leads, pads, and textures with distinctive personality. The instrument invites experimentation, inspiring new sonic possibilities by merging multiple classic tones into a single, dynamic performance.

Equipped with a fully customizable arpeggiator, Retro Synthstack provides the expressive control of an analog synth. Users can shape their tone with AHDSR envelopes and flexible filters before applying three unique LFOs targeting gain, pitch, and filter modulation. To further refine sounds, five built-in effects are included, making it easy to polish and personalize each patch within a single plugin.
