I would look into a larger power supply. That power supply “supplies a total of 1000mA … (500mA max per output).” Therefore, you don’t want to draw more than 1000mA from that power supply.
Here are the power requirements for each of the Singular Sound devices:
Aeros - 300mA
BeatBuddy - 500mA
Midi Maestro - 250mA
Total: 1050mA
The total power drawn by those pedals is 1050mA, but the rating for the power supply is only 1000mA. I would look for a power supply with at least 1500mA total.
