pad mode

Does anyone know if there's a way to use a midi note # to trigger multiple pads ( I know you can do this in the "pad mode" by physically hitting the a pad. Ex: hit pad 1A and have it trigger pads 1A,1D,2D 6C in sequence ). Wondering if I also can do this using an external triggering unit. I'm using an MPC1000 w/JJOS2XL
Thanks

Just to clarify what I mean by the above post: I'm using an electronic drum kit to trigger my MPC1000 JJOSXL.
I have a limited number of trigger pads. I'd like to be able to use one trigger pad to trigger four different samples. If I was playing directly on the MPC1000 pads, Id be able to utilize the the pad mode abilities to sequentially move through four different samples assigned to four different pads. But, because I'm triggering my MPC1000 using my electronic kit pads through midi, the above mentioned "pad mode" feature doesn't seem to apply.
