Synth Magic has released a free download for Native Instruments Kontakt.
The Wonky Tape Atari library features a collection of sound effects and instruments sampled from the Atari 2600 gaming console, recorded to a vintage Teac reel-to-reel tape.
I recorded an Atari 2600 with various games to a Teac reel to reel to make some atari percussion/drums and zaps etc.
Wonky Tape Atari requires a full version of Kontakt 5.2.1 or higher.
Make sure to check the Synth Magic site for some more quality free and commercial sample libraries.
