How to make custom Lmms instruments?

Anything that doesn't fit into other topics goes here!
Hello! I am a novice and I need help.

I have a MIDI keyboard connected to LMMS. I wish to connect 5 different sounds to each octave on the keyboard. As when I press keys on one octave- LMMS plays one particular sound in 7 different pitches, one pitch for each key; if I press different octave- LMMS plays totally different sound in 7 different pitches. All these different sounds are simply recorded with a microphone.

In that way I can use my keyboard as several instruments in one.

Is this possible? :)
no, not yet. It is something that may come later.
You could make a custom Soundfont instrument to do that, I think.
