Harmonic Tides: Aetherial String Instrument by Soundiron

The library has two primary sound sources. The first is a shimmering, airy texture made from layered cello harmonic glissandi, designed to add organic movement. Each key is sampled with four dynamic layers.

The second is a sharp, hollow sound made by bowing the after-length of double bass strings between the bridge and tailpiece. It is intended to add subtle tension. Both articulation sets cover a wide chromatic and dynamic range, so they can be played expressively from a keyboard or other MIDI controller.

Tides and Swells are kept as separate multi-timbre sets, giving you two distinct palettes to blend within one arrangement.

The Kontakt interface exposes automation-ready controls for swell, attack, release, offset, vibrato, filter, coarse and fine pitch, articulation switching and cross-fading between layers.

An adaptable LFO system offers selectable shape, modulation target, speed, intensity, tempo sync and fade-in time. Twelve lowpass, highpass and FX filters can be modulated by velocity, mod wheel, expression, aftertouch, key position or a step-sequencer table. A customizable arpeggiator and a key and scale lock help with melodic writing.

A modular FX rack provides 27 DSP modules across eight slots, and the reverb section includes 99 room, hall, chamber and outdoor impulse responses plus 40 custom FX impulses. Factory FX rack chain presets are included.
