This is the big one, nearly a year in the making and made by some of the hottest talent on the scene. 

Sonic Academy presents - 'Synthwave Sample Pack' An almighty 4GB of Arps, Bass, Drums, Pads, Vocals, MIDI files and 5 Massive Construction Kits. 

This pack has been meticulously built from classic synths such as Jupiter 8, Juno 106, Arp Odyessy, Korg Polysix and of course three Mini Moog.
Drum loops and the single hits have been expertly recorded through UAD preamps from drum machines such as the TR - 707, TR 727, Linn Drum LM-1, Oberheim DMX, Yamaha RX21, and processed through AMS RMX-16, SSL Buss Comp, DBX 160, Lexicon 224 reverbs, and Ampex tape machines. 

Sonic Academy assembled a team of Synthwave producers to make this pack the very best you can get. Just listen to the audio demos to understand the breadth and depth of the pack. Designed to allow mixing and matching of the folders so you can start producing and stop searching.

Synthwave Con Kit 05 - Master

Kraftkabel is the artist name of Philip I. Buckland. I am a musical scientist in a parallel universe living in a studio flat orbiting Jupiter. My keyboards are suspended in gravity nets, and my mixer is controlled by the power of the mind. My cosmic sequencing software masters through the power of emotion, and my keyboards are simultaneously both retro and new.
My music originates from the point of divergence of these universes - the mid-late 1980's, but is spliced by genre splicing interludes. I use a time machine and dimensional portal to get to work.
For the other nerds out there:
Hardware synths: 
Moog Subsequent 37; Roland Jupiter X, JD-Xi, VR-09, S-1; Korg Prologue, NTS-1, Monotron Duo; Sequential Take5; Yamaha DX7; Akai PRO MiniAK; Novation Mininova; Arturia MicroFreak; Modal SkulptsynthSE; Teenage Engineering PO-20.
Main software: Ableton, Arturia Analog Pro, InSidious, random free stuff from the interweb and Dexed to program the DX7. Audacity. All played through Arturia Keylab and Keystep (which has a better arpreggiator).
Plus some guitars that I can't really play very well. And an mbira, tin whistle and an alien head-shaped ukulele.
