> Only once
It might seem like a lot of downloading, but you only need to download the MAudio Plugins app and all of the content for MSoundFactory once and you will be good to go. You should also note that the Player is actually the full MSoundFactory for 15 days before it expires back to being just the Player. If you like the full version you can buy it for £255, but this tutorial and CM Pluck should work fine in the free Player alone.
