Yes, I know what you mean.

I don't have any experience with the GT-10's USB or drivers. I'm not sure 
where those settings originated from or what the GT-10 descriptors look like. 
I just know that the GT-10 and GR-55 are very similar devices and, nominally, 
part of the same product family.

The JS-8 is from the same vendor but is really a very different product. 
Obviously, despite this, there are some internal similarities.

Unfortunately whilst I have a JS-8, I don't have either a GT-10 or GR-55 (nor 
any other Roland/Boss USB audio product) with which to compare it. I have a 
GT-3, but that is a rather old model with no USB, so it's no use here.

I found the following old thread about the GT-10. I don't know if this sheds 
any light?
