31 * use existing instrument definition (from playmidi or kmid)
32 * with a .winerc option
33 * + have a look at OPL/3 ?
34 * + implement asynchronous playback of MidiHdr
35 * + implement STREAM'ed MidiHdr (question: how shall we share the

37 * the code for the low level driver)
38 * + use a more accurate read mechanism than the one of snooping on
