Alonso Sound is offering the 19 Year Anniversary Pack as a free download until August 31st, 2026.
This pack normally costs $35 and includes 128 presets for u-he Diva, Xfer Serum 2, Reveal Sound Spire, and LennarDigital Sylenth1. It includes 32 presets for each synth and covers leads, basses, plucks, pads, acid sounds, sequences, arps, keys, and synth patches for electronic dance music.
By the way, we covered Alonso Sound’s huge Revealed Free Tryout Archive last year. That pack bundled over 3.5 GB of free sounds from Alonso’s commercial sound design releases.
This anniversary pack is much smaller, but the idea is similar, and I like it. You get introduced to the sound designer’s work, keep the sounds you like, and support Alonso Sound with a purchase later if you want more.
Packs like this are great because there’s a high chance you’ll find some hidden nuggets if you own the required synths. You get a useful batch of presets for free, and even if only a handful become regular go-to sounds, that is still awesome.
All presets include mod wheel assignments, whereas the Serum 2 and Spire presets also have macro controls. The Serum 2 section includes 32 MIDI files, and the full download also includes the A19 anniversary artwork created by 3D artist LaczaDesign.
The Diva presets cover arps, basses, leads, pads, and plucks. Serum 2 has arps, basses, keys, leads, pads, and plucks. Spire is focused entirely on 32 sequence presets, while Sylenth1 includes arps, basses, leads, sequences, and one synth patch.
The included presets are 100% royalty-free, and all of them were made from scratch. You will need the full retail versions of the supported synths. The listed requirements are Diva 1.4.8 or later, Serum 2 version 2.1.2 or later, Sylenth1 3.0.73 or later, and Spire 1.5.16 or later.
Alonso 19 Year Anniversary Pack is available as a free checkout from the Alonso Sound website until August 31st, 2026. The compressed ZIP download is listed at around 26.6 MB.
