Frank, from where I bought the T4, I had emailed and he posted the answer here.
I have a skeleton outline of what those controls are all about on the T4 compressor from someone local, (a freind from GC), who has used compressors for piano, one of the tougher voices to keep sounding good from what I understand.
Here's the info:
Threshold, the most important factor. Has to do when does the volume threshold begin.
Ratio, once volume passes threshold, divided by what ratio is. Pushes volume down.
Threshold divided by Ratio
Gain Offset, allows to make up volume lost. Soft will be louder and loud note will be softer.
For EQ, if highs and lows are boosted may compress sooner.
Keep high EQ down.
Start testing with preset type, probably Basic. Then Threshold. Ratio up compressing more beyond threshold.
Avoid low extreme in Threshold. Avoid high setting in Ratio.
Gain should be in red only when really hammering the notes.
If anybody else has any good input it would be great to see it. Yamaha has kind of left us in the lurch with scanty info in the manual.
Best
