Abstract

PURPOSE:To enable to perform a tuning matching a conventional practice, by a method wherein, with a power source closed,a string assignment and a frequency are set to a condition matching a conventional practice. CONSTITUTION:With a power source closed, a signal IC is outputted from an initialize signal generating circuit 17. The signal IC is inputted to an encoder 23 through an OR gate 22, and a constant, being neccessary to measure a string 5A, is supplied to a CPU13 from the encoder 23. The signal IC is inputted to also a counter 30 to forcibly set it to an initial condition, and as a result, a pitch 440Hz is supplied as a constant to the CPU13. The CPU13 computes a constant, determined by a string and a pitch, from two constants to set it. As noted above, solely by closing a power source, a setting is done to the pitch 440 by the string 4A automatically determined beforehand, and this permits to perform a turning which matches a conventional practice.
