Recording more than two channels at the same time *on Linux*

Hi, I was trying to record several samples (channels) at the same time with Renoise, but I couldn’t figure out how.

I know I can use the “Sampler” -> “Rec…” function to record a max. of 2 channels (L + R), but what about more?

I was reading about people who found VST(?) plugins which record the output of “”#Line Input"to disk, but I couldn’t find anything similar for Linux.

Anyone knows if it is possible to do something like this With Renoise on Linux?

I would really be happy to get rid of any “intermediary” program like Audacity or Ardour.

Best thanks,
