The Quicknote charts clearly display the MIDI note number equivalent for each. In either case, the frequency is the same. Modes, scales and the correct notes within those scales are all readily available. Non-Registered Parameter Number LSB: For controllers 6, 38, 96, and 97, it selects the NRPN parameter. Note that the octave numbering differs between manufacturers, with some choosing to identify the octave of middle C (midi note 60) as octave #3, and others choosing octave #4 for the same note number. So we can rule out any issues with FL Studio. The best thing would be to first test the controller in another software or a MIDI monitor like MIDIOX. It's highly possible that your keyboard has a transpose feature that causes this. Also take care when a sub oscillator is used, as it will also be an octave lower than calculated. Re: MIDI Notes are mapped to the wrong piano roll notes. The 12' range will be an octave lower in frequency, while the 4' range will be an octave higher. In General MIDI, Channel 10 is reserved for percussion sets. When using a synthesizer with several choices for oscillator range, the 8' range should match the calculated frequency. Instruments can be selected by using the MIDI command byte (0xc0) followed by a data byte which is one of the above numbers (minus 1). For your reference, we have calculated frequencies for all of the midi notes and included the note name and octave numbers in the table below.
