with no input on the vcxfade input, indeed you should only hear input 1 on the fully left setting of the xfade knob and input 2 on the fully right.
as for the lfo crossfading:
IIRC, the whole xfading takes place with a positive only voltage from 0 to 5 volts and with the xfade knob on the fully left position. (someone correct me if i'm wrong)
also, bear in mind, that the vcxfade input, does not have an attenuator, so to achieve nice crossfading, with some cv sources, you will probably need an attenuator before the vcxfade input.

Hey all,
I’m trying to get my head around what the X Fader can and can’t do. According to the module info, if I have two audio signals plugged into it, then as one signal fades in volume, the other should increase. But I’m having trouble finding a patch that will demonstrate this. Instead I find that both signals fade or get louder together.
For example, on the Creature, I patched the left-hand TGO sawtooth to XFAD input 1, and the right-hand TGO triangle to XFAD input 2, and I LFO modulated the amplitude of input 1. I would expect the input 2 signal to grow stronger and weaker as the input 1 signal modulates. But I only hear the input 1 signal modulating while the input 2 signal stays static.
Also, the X FADE knob doesn’t do what I would expect either. My expectation was that since the label reads “1 XFADE 2”, then if the knob was all the way to the left you’d only hear input 1, if the knob was all the way to the right you’d only hear input 2, and if it was in the center you’d hear each equally. Instead, I hear both signals at full strength full-left or full-right, and nothing at all at dead-center. The only difference between hard-left and hard-right (as viewed on my oscilloscope) is that one is the inverted combined waveform of the other.
Lastly, an LFO applied to the VC XFADE jack alternates between hard-left and hard-right (with full input 1 and input 2 signal strength with each swing). And an LFO applied to the VC GAIN jack modulates the amplitude of the combined signals.
At the very least, I thought the X FAD module would be like a two input mixer, but that doesn’t seem to be right either.
So thus far, I seem unable to get any true cross-fading happening between input 1 and input 2. Perhaps I’m not getting what “equal-power cross fade unit” means? Can someone help me understand this module better?
Thanks!
