I have from time to time realized at least a "semi-passion" for pedal steel guitar, though my PSG emulation on keyboard has been mediocre, but I'll tell you what I've learned.

You must utilize pitch bend (obvious) and a volume pedal (not so obvious). Listen to a real PSG and you will hear bends up, bends down, single note bends within a chord, and cresendos within a single note or chord. This is frequently used, therefore the need for volume pedal. You will also hear delayed vibratos as well as immediate vibratos. Aftertouch delay is a good choice.

Portamento does not work, at least not for me. Perhaps with the foot pedal using it ocassionally it would. Glide is a function not present in the SD1, I'm curious how it alone would work. Interestingly, the voice used seems to be not that important. The best MIDI PSG I ever heard used a GM flute voice!

Keep listening to PSG and try to objectively analyze what's happening to make each and every sound you hear. I once found an internet radio station that played pedal steel guitar music 24/7. Must be some people who are more than semi-passionate about that sound.
