Hey I know I've seen this asked a few times but its getting time to replace my cartridges. I've seen the thing about rubber banding floss in the black cartridges, how exactly do you do that? When you do that do you also use the media containers? Doing the rubber band thing seems like you would get some bypass, though I don't know exactly how you do it. I was thinking it would be cool to just cram floss in the media containers, and not use the black ones at all, but it seems like the rubber banding people would have thought of floss in the media containers so I must be missing something. Actually I have some wrong sized ehfi synth pads I thought I would cut up and use for that, but that would only be like one application's worth of material. I actually have 2 extra media containers too I might incorporate somehow.
