Yamaha TX81Z Lately Bass | FM Bass Multi-Sample for Serum 2

Every sample is captured from original Yamaha TX81Z hardware, 588 samples across 12 velocity layers at 24-bit/48kHz, processed through a Neve 1073 DPX channel strip. The authentic FM synthesis character, the distinctive metallic harmonic content, and the percussive attack of the C15 preset are preserved exactly as they came from the hardware.

All three are built from the identical 588-sample, 12-velocity-layer capture. Serum 2 (~375MB) works in any DAW running Serum 2.0+ with 8 macro controls. The Ableton Rack (~1.1GB) integrates natively into Live 12 with macros optimised for Session/Arrangement workflows.

The SoundFont (~328MB) offers maximum cross-platform flexibility — load it in any SoundFont-compatible sampler without needing Serum or Ableton. Serum 2 and Ableton Rack both include the 8 macro controls; SoundFont delivers the raw multi-sample.

The TX81Z C15 Lately Bass is the foundational FM bass of UK acid house, early rave, and hardcore from 1988 to 1995, the bass on Orbital’s “Chime,” Gat Decor’s “Passion,” and Lil’ Louis’s “French Kiss.” In modern production it works in deep house, tech house, UK garage, and any track drawing on British underground heritage.

Yes, fully. Every sample, MIDI loop, and WAV render is cleared for commercial release, sync placement, and client work — no attribution required, no per-release fees. Full licence terms at producerstack.com/policies/terms-of-service.

Free TX81Z SFZ packs exist on FreeWaveSamples and the Bedroom Producers Blog, typically a single velocity layer from an unprocessed capture. This pack delivers 12 velocity layers across 49 notes through a Neve 1073 DPX signal chain, with 40 MIDI loops and 8 intelligently mapped macro controls in Serum 2 and Ableton formats.

The free versions will give you the rough shape of the sound; this pack gives you the depth, dynamic range, and production-ready integration that the freeware versions don’t.
