SPD-SX Pro Master Effects

[gregdei]

Hi there,
with my old SPD-SX, I can quickly switch between reverb and echo for a few dub interludes by turning on one of the master effects.
Now I see only one switch on the SPD-SX Pro for the Master Effect. Does that mean I can only turn on and off a single pre-selected effect?
Also, I have been working a lot with the delay repeat and volume. Is that still possible?
🤔
