Hello!
I meant to send this last weekend, but never got around to doing it. This is the QWS instrument definition list for the Roland EXR-7s, which will probably work for the EXR-5s and EXR-3s as well, and possibly even for the EXR-3/5/7 (older models, without the "s" at the end). The EXR-7s has the most tones of all the models, so the numbering in the patch names is probably wrong for the others in this series. Anyway, here it is: http://www.davykager.nl/uploads/INST_EXR-7s.ini
