--- SpGold version 4.09 Update ---
1) MASTER sync mode - When Sp Gold is in MASTER sync mode, it uses its own
internal clock as a timing reference and simultaneously generates SMPTE from
the V-24s SMPTE output. This mode allows Sp Gold to send SMPTE to another
hardware device or a MIDI/digital audio application running simultaneously on
another computer, such as Digidesign Sound Tools/Pro Tools/Deck, Turtle Beach
56K, MTU MicroSound, etc. MASTER also allows you to record your MIDI tracks
and your SMPTE stripe onto tape at the same time.
2) All SAPI drivers (except SAPIMFC) are now General MIDI-compliant.
*SAPI's default patch and drum note mapping are identical to those defined by
the General MIDI standard. 
*SAPI uses channel 16 (*NOT channel 10*) as its drum channel.
3)New Librarian support: Roland D-70, Ensoniq SQ-1 Plus and SQ-2, Kawai XD-5,
Korg 01/W, Korg Wavestation A/D.
4)New hardware support: PAiA PCM68ex, 4-operator Sound Blaster Pro.
5).PIF and .ICO file to use for running Sp from within Windows.
