The current iteration of Renoise incites the user to get back to basics and use samples for sound design and instrument creation. However, in order to create a big bunch of different instruments just a few samples can be used, e.g. one can use a single sine wave to generate whole drumkits but to do that one has to copy samples over and over, increasing the module size, as well as increasing the amount of time it takes to save a song.
It could be circumvented by reusing samples. For example, one could use aliases the same way as in the Matrix view, where a sample from a specific instrument can be aliased to other instruments. It appears that it should be easy enough to embed into the current GUI, for instance one could do:
right click on a specific sample -> select “Copy as Alias”
then switch to the target instrument:
right click on an empty sample -> select “Insert as Alias”
In this fashion one would not be forced to have duplicate samples in the song.
