Sampleing in piano roll lv2 or dssi plugins?

[machine]

Hello
I just bought some midi controller pads and want to use it to control drums and other sample's. But my current DAW (LMMS) only allows one sample per piano roll. So I was wondering if there were any lv2 or dssi plug-ins to use multiple samples in one piano roll. Btw is ladspa only used for effects or is it used for instruments too? Anyway if anybody could help me with this I would be very gratefull.

The linuxsampler lv2 plugin can have multiple samples loaded. Also if it is possible to route the midi out of your midi track to another midi track you can run multiple midi instruments from one track. I am not familiar with LMMS, but you can do this with Ardour3, for example.
