Convert frequency to MIDI note numbers at signal-rate ftom~ performs signal-rate frequency (Hz) to MIDI(note-value) conversion. Cycling '74 MSP MSP Operators Frequency in Hz TEXT_HERE Frequency in Hz TEXT_HERE Floating-point MIDI Value TEXT_HERE TEXT_HERE TEXT_HERE Input frequency value (as a signal) A signal representing a frequency value. It is converted to a MIDI pitch value (from 0 to 127) and output as a signal. Base frequency for conversion Sets the "base frequency" used when converting frequency values (e.g., A = 440.). The default is 440. The MIDI note value that corresponds to the input frequency is output as a signal. When an input frequency falls between two equal tempered pitches, the fractional part of the MIDI value is included.
