Recent news is MusicRadar keep sharing giant sample pack one by one. Generally electronic genre sample pack it can be downloaded from MusicRadar site. And the second pack is clearly classic orchestral by Sonatina Symphonic Orchestra which are also free which quite rare comparing to any electronic stuff out there.
And btw, there is coming redesign of SynthOfMine.com site. If you have any additional ideas or synths to review then feel free to contact me or comment any post at the blog! Thanks!
