XR22 VCO FTAM (and ring modulation)AndFSK (Frequency Shift Keying)This is a unique analog oscillator that can change the tone in such a way. It has extremely analog sound quality even when it contains dissonances and intense overtones, making it a powerful weapon for synthesizing analog percussion sounds.
 

AM

 AM adds metallic harmonics and dissonance by controlling the amplitude (intensity) of the sound source with a voltage (at the audio rate). You can also use your own (waveform output) as the modulation source for AM. AM here is a ring modulation, so if you increase the modulation until the AM equivalent to a negative voltage is applied, it will be an AM with inversion of the oscillator waveform.
 

Frequency Shift Keying

 This mode (FSK mode) allows the rising and falling frequencies to be controlled separately. When the FSK mode switch is set to the down position, the frequency is set by F1 when the square wave output is high (when the sine / triangle wave output signal is rising) and F2 when the square wave output is low (when the sine / triangle wave output signal is falling). Will be determined. For this reason, the output of the triangular wave has a different waveform for the rising and falling waves, and you can change not only the pitch but also the timbre by moving F1 / F2.

 In FSK, the pitch control is a little difficult because the waveform changes depending on F1 and F2,Combination switchIs helpful. When the switch is down and the combination mode is enabled, F1 can control both F1 and F2, so you can also control the pitch while maintaining the waveform.
