  This paper presents developments in the technology underlying the
cyclotactor, a finger-based tactile I/O device for musical interaction. These
include significant improvements both in the basic characteristics of tactile
interaction and in the related (vibro)tactile sample rates, latencies, and
timing precision. After presenting the new prototype's tactile output force
landscape, some of the new possibilities for interaction are discussed,
especially those for musical interaction with zero audio/tactile latency.
