What is Freesound Simple Sampler?
This is a simple sampler that allows users to make a query to Freesound and build a sampler based on the first 16 results. Sounds are automatically mapped in the full MIDI note range.

If you are interested in the technical details of how this was built, check out the tutorial here.
Also, if you want to create custom racks of samples using Freesound, there is an ongoing plugin currently in development called Freesound Rack. This plugin can be accessed at https://mtg-toolbox.github.io/ready-to-use-apps/freesound-rack-plugin/.
