You can play any Automatic expression roll or Ampico / Duo-Art / Welte reproducing piano roll on a standard 88-note player piano by simply taping over the unneeded channels of your tracker bar with every-day Scotch tape. I usually use a piece about 2" long, loop the last 1/4" back on itself for easy removal later on, then cover the undesired channels as shown below. I let the tape extend vertically above and below the face of the tracker bar so the roll can't snag on it during play or rewind, and I never have any problems.

Notice that 4 of these 5 systems provide for the same automatic sustain channel, so don't cover that channel with tape! To add sustain while playing Welte rolls you'll want to watch the on / off signals in the roll and manually activate the sustain yourself. Don't worry, it's easy! Sometimes you can see the tape through recut roll paper, which makes it easier to keep track of the sustain on / off signals. Now you can listen to your reproducing rolls with as many levels of expression as your little heart (and feet) desire. Have fun! ;-)
