buffers: sample loading

[andr-ew]

• K1 + buffer to load file
  • in-app file browser
  • files are auto loaded to buffer as they’re selected in the browser for previewing
  • last dir is saved between file loads/sessions so you can quickly load files
  • keypress to disable auto preview
  • just holding buffer for a helf-sec or so might actually be sufficient. buffer isn't a super performative component to accidental triggers for sample load might be unlikely
    • though, there is a higher consequence for accidental triggers, just opening the menu might effectively reset the buffer
    • what if the gesture only worked on a blank buffer?

simpler option: just use the fileselect param
