Triggering 2x s950 samples from SP1200

Hi there...

I'm really hoping you can shed some light for me. I can trigger one 950 sample (e.g. bassline) from an SP pad, but can't seem to trigger additional samples on adjacent pads.

What I have done on the S950 is:
- Assigned a different keygroup to the 2nd sample e.g. KG2
- Assigned the sample to the SP pad e.g. Low Key (& High Key) G1# 44
- Assigned a new output e.g. output 2
- Chosen one-shot on pg15 in EDIT PROGRAM

In the MIDI section/function I have set OMNI to off and have checked (on pg3) that when I hit the SP pad the midi message is being received.

The basic midi channel on the S950 is set to 1 and I have tried offsetting feature in EDIT PROGRAM which has not helped (I was really just troubleshooting here!)...

On the SP1200, I programmed the MIDI PARAMETERS (>>SetUp>>22) to Basic Channel 1 & set it to POLY mode and did not pitch keys....

What else should I try??? I basically want to trigger more than one sample on s950 and of course, be able to press different SP1200 pads and here the different 950 samples...

What to do??? It seems that this is definitely possible because I keep hearing of people who have allegedly had success...but I just cannot seem to get more information from them directly!

I will be mad grateful for some helpful assistance...
Many thanks,
D.
