The curves at the top of the page are standard piano roll scrolling curves. The Standard methods use the Filter envelope, the Clip envelope and it's own internal envelope and are designed to be the most flexible technique for playing melodies with a vocoder. The 'Noise suppression' method doesn't use a generator but the sample rate of it's signal is always set to 288000 (sample rate of original source signal). This method is designed to filter out noise resulting from the envelopes in the Vocodex. The 'Immediate' method uses the internal Carrier generator that also tracks the multiple Modulator sources and also has its own internal envelope.
The vocalization of the Demo Vocodex Chords tend to be a little'softer' than those of the Vocodex Chords from the Packages. On the 711 and 718 packs the resonances (1st and 2nd harmonics) of the note are filtered out from the VOCODEX Chords. The demo vocodex Chords do not have that option to cut the resonances. The Demo sounds a little bit thinner and less harmonically rich than the packages. This is because the sample rate of the Demo is 48000Hz and that of the packages is 44.1kHz.
If you are recording your own vocals in the Fourier domain, such as for learning how to record your own vocal performances in the frequency domain with Vocodex, please consider using a microphone clip filter/gate in your recording software to prevent the reflections of the vocalization from being recorded back. When you record, the spectrogram (the visual representation of an audio signal) will demonstrably filter out your vocalization at the beginning and end of your section. You don't get to hear that reflected back thrown up by your microphone when you run your vocalization through a clip filter/gate.
The envelopes are written at a rate of 16.7ms / 1 Sample and a rate of 163ms / Sample for the Clip and Filter envelopes. The Rate of the Filter envelope determines how much of the original signal is used to compute the envelope. d2c66b5586
