Advance warning so you can start practising to record something!
Scores of 30 voluntaries and one of the opus 10 concertos are available on WIMA with electronic samples/midi of most
Some also on IMSLP.
Many of the voluntaries and some of his concerti are also on Youtube, you can also find some of his works on the NPOR site played on historic English instruments.
Only one of his Opus 10 concertos, number 4, is on youtube with organ and strings, some others of opus 10 and opus 2 are there in string only arrangements. I've yet to find recordings of any of his oratorios/cantatas, I believe there are scores available, although maybe not complete.
