Harmonic Tides Black Friday Deal 2026: $24.50, 50% off

The Harmonic Tides Black Friday deal puts Soundiron's Kontakt library of cello and double bass harmonics at $24.50, 50% off, until Dec 6, 2026.

Harmonic Tides is a sound-designed string library, and the maker calls its sound aetherial. It was created by Soundiron collaborator Pierce Constanti as a film-scoring tool meant to be as expressive and nuanced as a typical orchestral string library.

The maker pitches it at modern arrangements and film and game scores that need lush swells and big waves of emotion.

What is Harmonic Tides?

It has two main sound sources. The first is an airy, shimmering texture built from layered celli harmonic glissandi, meant to add organic movement. Every key is sampled with four dynamic layers.

The second is a sharp, hollow tone made by bowing the after-length of double bass strings between the bridge and tailpiece. The maker says it adds subtle tension and movement.

Both articulation sets cover a wide chromatic and dynamic range, so you can play them live from a keyboard or other MIDI controller.

How was it recorded?

Close microphones captured every detail of the celli and basses, and up to eight stacked solo takes are spread across the stereo field around the listener. The unusual performances and extra processing disguise the instruments' origin, so the result sits closer to a pad or drone than an orchestral section.

Blend the multi-dynamic layers and you get swells and textural waves. Soundiron has also expanded the source into leads, pads, short notes, stingers, fluid atmospheres and textures.

What is in the Kontakt interface?

• Automation-ready controls for swell, attack, release, offset, vibrato, filter, pitch (coarse and fine), articulation switching, cross-fading and layering
• An LFO with selectable shape, target parameter, speed, intensity, tempo-sync and fade-in time
• 12 lowpass, high-pass and FX filters with assignable modulation targets
• An arpeggiator with a velocity table and control over direction, timing, swing, randomization and duration
• Key and scale lock for easy melodic playing
• An FX rack with 27 DSP modules across 8 slots, plus factory chain presets

The reverb section holds 99 convolution impulses of rooms, halls, chambers and outdoor spaces, plus 40 custom FX impulses for more extreme sound shaping.
