If both envelopes are set to FIXED in the patch, and you're sending data in on the basic channel, the same channel that the internal keyboard plays on, then I don't see how they could sound different.

If either envelope is set to TOUCH, then the velocity curve of the keyboard becomes a factor.

If you're sending MIDI into a different channel, then the levels could be set differently between the basic channel that the internal keyboard plays on and the other channel that the external keyboard is playing on. The Polaris uses control change 0 for volume (this was before the MMA assigned that to Bank Select, and assigned 7 to Volume). On startup, the Polaris sets this to 96, I believe, and I don't think there's anything that changes that internally. Is it possible that some higher value of CC0 was sent in from the external device? Or do you have a way to send arbitrary values? If you do, you could try sending CC0 = 96, and maybe that would equalize it. But I wouldn't expect any of this to be necessary.
