Very curious how this was programmed.. You said it was made with some kind of Band pass filter plugin? email me the name of the plugin if so, jamesloganfl@gmail.com
in fl the basic sampler can do lp bp bs hp with osc for pan, vol, cut, res, pitch, usually i put drums into it but whole loops n stuff can be loaded in as well
