Convert a MIDI note number to frequency at signal rate Use the mtof~ object to perform signal-rate MIDI-to-Frequency conversion. Cycling '74 MSP MSP Operators Floating-point MIDI Value TEXT_HERE Floating-point MIDI Value TEXT_HERE Frequency in Hz TEXT_HERE TEXT_HERE TEXT_HERE A signal representing a MIDI note number value (from 0 to 127) A signal representing a MIDI note number value (from 0 to 127). The corresponding frequency is output as a signal. Base frequency Sets the "base frequency" used when calculating frequency values (e.g., A = 440.). The default is 440. The frequency corresponding to the received MIDI pitch value, output as a signal.
