Hey guys thank you for your help!!
Brad…I tried selecting various GM tones but unfortunately it had no effect. Also, thanks for referring me to the tone charts! That’s how I figured which tones I was hearing and their program change values. (see below)
Jokeyman123…I purchased my Korg back in 87’ so I’m pretty sure it’s all original. If you can recommend a retrofit kit, that would be great!
So I tried connecting the PX to my Ensoniq Mirage DSK and discovered something interesting. In the Mirage parameters I can select the midi channel. If I have the Mirage midi channel set on 1-9 & 11-16, the PX’s GM Piano 1 tone is heard (this patch has a program change value of 0). If the Mirage midi channel is set to 10, the PX’s GM Standard Set 1 tone is heard (this patch also has a program change value of 0). No other tones are heard.
Based on this, I’m guessing my Korg only sends/receives tones with a program change value of 0?
On a side note…when I reverse the midi connections and send tones from the Korg to the PX, everything works great. Probably because the PX is 30 years younger, lol.
