If you have a single sample that you want to send into stuff, I would use the sample player built into Reaktor on the menu bar. If you have 128 samples with velocity layers - use a sample map. Somewhere in between use a table list. The first two approaches are easy to use because the player 'just works' and the Primary samplers that use the sample map are relatively simple to hook up. I don't see a problem dragging even a single sample from the GUI browser panel into the whole sample map. I have favorite folders set up with lots of sample locations preset so I can easily drag in many kinds of sounds. The Table List does no sound - so you need to build the sampler. Look at Colin's simple example to get an idea of how much building may be required to use it. I know Colin just made a simple example and a more polished instrument might be easy to use as well. I don't know of any way one could attach a Table List to an existing Primary sampler. But try to grab some of the sample player stuff from FORM and try to use that. I'm sure it is very well-designed, but it doesn't survive long as a learning tool, even for experienced builders. Blocks are fun and easy to use, but they are not polyphonic. Just about everything else in Primary is and always was. In Reaktor, instrument outputs are multi-channel or stereo, but only one voice. Blocks are instruments in Reaktor. So outputs are 'multi' but the driving inputs are 'mono'.
