Congrats Serato on making a great sampler - it is really easy to get going quickly and I really enjoy the waveform view and how you can just drop in your sample start points.
I work in Cubase and this is no doubt a great addition for my workflow. The new sampler in Cubase is too simple and TAL Sampler and Kontakt takes too much work to get going. Not to mention how bad the Kontakt GUI is - oh the terror.
anyways I really hope for you focus your next updates to make it possible to name each pad and have separate outputs for each pad.
the bpm and key detection seems to work perfect for me so far :)
