The Peterson V-SAM Virtual Strobe Tuner/Metronome is a Virtual Strobe tuner, audio tone generator, and metronome in a compact format. Its tuner modes expand upon the V-SAM with an even wider variety of alternate temperaments including one that creates and stores custom temperaments. It automatically detects notes accurately to 1/1000th of a semitone. Its ultrawide 410 to 490Hz range for concert A reference makes it perfect for use with early instruments such as harpsichord, lute, recorder, and Baroque flute. The high-output tone generator within V-SAM offers an unprecedented 10 octaves of audible tones, adjustable in 0.1-cent increments. Its audio/visual metronome allows tap or dial-in tempo, adjustable beats per measure, beat subdivisions, and a stopwatch function.
