Description
The Aftermarket – K4 sample pack for Logic Sampler / EXS dives deep into Kawai’s distinctive K4 synthesizer, a machine that epitomizes the raw, grittier sound of late 80s electronic music. Where other synths played it safe, the K4 ventured into new territories – perfect for producers crafting lo-fi, big-beat, and trip-hop landscapes.
Over the years, I’ve been fascinated by the K4’s unique Digital Multi Spectrum synthesis. The filters sound great, and at it’s core, the wave ROM design is spot on – a Kawai strength. Its innovative approach – splitting 16-bit samples across ROM chips and reserving a dedicated chip for 8-bit noise samples – created a sound palette that was simultaneously industrial and musical. They’re the secret weapon in this collection.
Demo:
This comprehensive library, using the SoundEngine’s Waveform Machining process, captures over 3,150 meticulously sampled 24-bit sounds, representing more than 160 carefully crafted presets. Recorded through a PreSonus StudioLive console at 48 kHz and refined in Wavelab and Izotope RX11, each sample preserves the K4’s characteristic digital texture while offering modern electronic music-making flexibility via Logic Sampler/EXS.
Organized for intuitive exploration, the sample pack features folders like “AP Acoustic Piano,” “GT Guitar,” and “KY Keyboard.” We’ve moved beyond the K4’s original numeric naming, creating an easy-to-navigate library that lets you quickly dial in exactly the sound you’re seeking.
Whether you’re a sound design adventurer or a producer looking to inject some vintage digital grit into your tracks, the library offers a passport to a forgotten corner of synthesizer history. Explore and transform – with the Aftermarket – K4 sample pack for Logic Sampler/EXS.
