The Struck Grand Black Friday deal takes 50% off this Soundiron prepared piano library for Kontakt, so it comes to $39.50 until Dec 6, 2026.
It is a 9 GB virtual prepared piano built around the unusual things you can do to piano strings.
The source is a 1926 Steinway Model L parlor grand, sampled across the full 88-key range. Soundiron captured more than 4000 samples of it.
Struck Grand Piano skips conventional playing and samples unconventional ways of working the instrument, such as hitting strings with mallets, damping them by hand, plucking, bending notes with a steel slide, dragging across the low strings, sounding harmonics and tapping with metal hammers.
The maker describes it as working both as a melodic tuned percussion instrument and as a big stringed zither. It covers a broad pitch range with expressive dynamic response.
Soundiron says each articulation was recorded up close, with rumbling bass and glistening highs.
The maker points to the Struck, Harmonic, Mallet and Gliss elements for dramatic, suspenseful scoring. The Steel Hammer, Slide and Picked sections lean toward a nuanced classical feel.
Two control systems sit at the centre of the instrument.
The Layer Builder lets you blend up to 12 independent articulation layers into one sound.
The Gliss/Strum Creator plays strums and string glisses for you. Its controls cover:
Every parameter can be automated on the fly, which the maker says allows organic, evolving performances.
The articulation sets are:
There is also a Master Layer Builder preset set and an effects section.
A bonus selection of atmospheric pads, tonal drones and evolving soundscapes can be morphed and shaped in real time. You also get fully automatable LFO, EQ and filter, plus custom room/FX reverb types.
This is an open-format Kontakt library designed for the full retail version of Native Instruments Kontakt 4.2.4 or later. The maker also states that the full version of Kontakt 5.5 or above is required. The free Kontakt Player only runs it in demo mode.
The library does not appear in the Libraries tab. Load it through the standard File browser tab, or import it into the Kontakt database and Quickload tools.
The install holds 40.nki files (36 for Kontakt 4, 4 for Kontakt 5) and 4,058 samples. They are 24 bit / 48kHz uncompressed PCM wav, and the presets and samples are unlocked. You can map the wav files into other wav-compatible samplers and synths.
The maker lists Windows 7 or higher or Mac OSX 10.9 or higher, a dual-core CPU and 2 GB of RAM. A SATA or SSD drive is recommended.
Yes. The Struck Grand Black Friday deal takes 50% off Soundiron's prepared piano library for Kontakt, bringing it to $39.50. The offer ends Dec 6, 2026.
You get a 9 GB library with 4,058 samples of a 1926 Steinway Model L, 40.nki files, the Layer Builder and Gliss/Strum Creator, a bonus set of pads, drones and soundscapes, plus LFO, EQ, filter and reverb.
No. It is an open-format library that needs the full retail version of Native Instruments Kontakt. In the free Kontakt Player it only runs in demo mode, and it will not show in the Libraries tab.
The library captures a wide range of techniques on the piano's strings and frame, from struck and plucked notes to sliding steel bends, scraped low strings, ringing overtones and hits with metal hammers. Fingered and picked glisses, strums and ambient soundscapes round out the set.
