I've been using the Roland PDX-100 for a while now, and I've found a few things that really help maximize its potential. First, try experimenting with the trigger sensitivity settings on your drum module. This can dramatically change the feel and responsiveness, making it more tailored to your playing style. Compared to other pads, like the Yamaha TCS pads, I find the mesh head on the PDX-100 offers a more natural rebound, which is crucial for dynamic playing.
For maintenance, ensure you periodically check the tension of the mesh head. Keeping it evenly tightened maintains its responsiveness and extends its lifespan. Also, be cautious with your sticks; softer tips can help preserve the mesh.
What module are you using it with? Maybe we can exchange some more tweaks specific to your setup!
