We all commented on a built in tuner as well that is on the backlog list https://trello.com/c/7HQ6Qs9f/184-built-in-tuner-for-instrument-tuning. I agree that there are many available tuners (I like the S-gear Tuner) but… would having it integrated in C3 help address some of Neil’s requirements (selective muting) since the muting could be possibly controlled by special routines unique to the built in tuner or make it easier to access?
