Plugin Boutique has launched a promotion on the Ultimate Synths expansion pack by Beat for the free Zampler virtual instrument.

Beat spent a lot of time to get the best from synth powerhouses like DUNE 2, Serum, Sylenth1, Discovery Pro, Spire and DIVA.

The result is a stunning Zampler Pack featuring 2 GB of sample content with 64 patches from basses, leads, pads, and FX which organically blend into various electronic styles.

The Ultimate Synths Expansion is only £4.95 GBP / $6 USD until the end of February.

To use the expansion you will need Zampler 1.0.2 or higher, which is free to download in 64-bit VST and AU plugin formats for Windows and Mac.
