29 Advanced input models

In an earlier chapter, we introduced Libmarpa’s concept of input, and described its basic input models. See Input. In this chapter we describe Libmarpa’s advanced models of input. These advanced input models have attracted considerable interest. However, they have seen little actual use so far, and for that reason we delayed their consideration until now.

A Libmarpa input model is advanced if it allows tokens of length other than 1. The advanced input models are also called variable-length token models because they allow the token length to vary from the “normal” length of 1.
