Entonal Studio

I've been making music in just intonation for many years now, and have tried most of the software and plugins. MTS-ESP is a godsend for syncing tunings across hardware and software instruments. It's just incredible. Having tried several of the newer plugins that use this format, Entonal Studio stands out as the most intuitive to use, as well as being vibrantly clear in illustrating the structures of different tuning systems. Particularly, the lattice view, as well as the measurement tool that shows you to see the frequency ratios of any tuning in realtime as you play intervals. Incredibly useful and makes microtuning much more approachable than anything else out there.
