One aspect, that is rarely covered in reviews, came to my attention with Initial Audio. Everything is made to make it most comfortable for you. A new version of your plugin appears? You get a special updater, that only installs, what actually was updated. Where other companies just let you download the 4 GB synth over and over again, this is not the case here. No annoying “plugin manager” software, a hassle-free installation, that remembers the paths you installed previously, and a non-intrusive copy protection complete the top impression.
Even if products like Sektor or Slice were not as good as they are, I would buy here just for these conveniences alone.
