JRR Sounds DX∞ 4Op Stock Set

The Yamaha TX81Z was the most advanced version of the low-priced follow-ups to the famous (or infamous, depending on how you view 80's music) DX7 FM synthesizer. While it had only 4-Operators compared to the DX7's 6, the TX81Z offered many more waveform options and thus could create even rougher, more complex, and more interesting sounds. Furthemore, the distinctive 4-Operator sound became the trademark of early techno and house pioneers.

DX∞ 4Op Custom Set consists 83 patches and 1.2GB of audio painstakingly sampled through vintage UTC isolation transformers and state-of-the-art Lynx conversion. It is a noisy and esoteric collection of basses, bells, pads, keys, and even drums that put FM synthesis in a light seldom heard before.

To install your new JRR Sounds library, simply move your downloaded zip file to your favorite sample folder and extract it from there. A folder called JRR Sounds will be created and inside it will be the individual folders for any JRR Sounds libraries you have purchased. If you have already purchased JRR Sounds libraries in the past, the new folder(s) will now show up in the JRR Sounds folder that had previously been created.

Once installed, please either drag and drop or open your new library from within your compatible sampler plugin.
