I have had the previous generation Roland SPD-SX for several years now, accompanying me on numerous performances and tours. Although I was generally satisfied, there were also many drawbacks, such as insufficient expandable memory capacity and limited sampling rate options of only 44.1 kHz. Several years ago, a red version was released, but it didn't offer significant improvements and was essentially the same level of product.
However, the new SPD-SX Pro has truly revolutionized my experience! The much larger full-color screen makes it incredibly easy to see the current pad's sound and attributes (loop, one-shot, etc.), and the added control over the hi-hat opens up even more possibilities for expanding triggers. You can even layer two sounds and control their balance within this compact device. I can only say it's mind-blowing. This machine is in a completely different league from the previous SPD-SX. If you're still using the previous generation, don't hesitate—get this one, and you'll absolutely fall in love with it!
