Pitchmaster is an ad-free, highly accurate musical instrument tuner and tone generator. Built by a musician for himself and his friends, Pitchmaster does the job for reeds, brass, and strings. The reference pitch can be adjusted up or down from A=440 hz and an input sensitivity control allows tuning in both quiet and noisy environments. The tuner also features a frequency response display that gives a visual indication of tone, especially useful for instrumentalists seeking consistency across the range of their instruments.
