Samplab is a new application that allows you to convert polyphonic audio to midi. The best thing about this product is that it is free to use ( for now). This plugin comes primarily in VST3 format but in this video, I demonstrate how you can use this product in DAWs like Reason or any other DAW that does not offer VST 3 support yet. Try it out in the link below.
