I think the T3 waveform ROM is the same as the M1 EX (or M1R EX). The T series machines have the same 8MB of wave data as the M1, plus an addition 8MB. This was later offered as the 'EX' upgrade to the M1/R.

So if you can't find the default patch bank from another T series user, the M1/R EX data should be identical.
