It should be in an effects loop rather than into the front end of a cranked up amp….
Anything into a distorted amp will be noisy.ANYTHING

Sorry it was designed for guitar NOT for keyboards and I personally do not recommend it.
I wish it was never mentioned by marketing.
To use with a keyboard you need to play no more than 4 or 5 notes at one, stay with in the range of a guitar and play using a sound like a guitar.
Also close voicing does not work well on keyboards.

Sorry that is terrible.

Make sure you are using the EHX supply…

Not familiar with that amp or the switching it system it uses. You are best to talk with the amp company. Here is the manual for the Superswitcher:

Guitar amp is fine unless you want loud.
For loud a good bass amp.
