The amount parameter controls the proportion in the output signal between a signal without the effect (dry) and the same signal with the effect (wet). Amount zero means only dry signal, amount at maximum means only wet signal. So it is not the depth of the tremolo or PAN you are controlling but the mix between the dry signal and the wet signal.

We are talking about amplitude modulation. I think that dry/wet (which would be akin the rescaled sum of both signals in different proportions) and depth come to the same result.
You can test that in the NS2, set 2 slots with 2 identical pianos, one of them with full tremolo, the other without and play around with the slot levels.
The only thing is that when fully wet it might not be as deep as you want.

Hi to you all,
Thanks for your anwers, this is more clear.
Let's play Tremolo now , dry and wet, with my pedal.

Regards,

I may have contributed greatly to your confusion, De fursak. I usually have Nord Stage architecture on my brain. The Stage has independent knob controls for rate and dry/wet mix. That's what was in my brain when I wrote that, sorry. Your NE5 does not have the front panel wet/dry mix control that I was referring to. Completely my bad.

I strongly suspect (and will attempt to confirm) that the control pedal function controls dry/wet mix.

As stated earlier, the depth of tremolo is controlled by selecting Trem 1, Trem 2, or both (sort of Trem 3).

Theoretically speaking, controlling dry/wet mix is not exactly the same as controlling depth of effect. Effect depth can vary from slight to radical. Dry/wet mix can vary from 100% dry (original, uneffected signal only) to 100% wet (effected signal only). Depth of effect is perhaps more clearly illustrated when considering a synth situation in which the LFO is set to modulate OSC 2 pitch. At a mild depth, the osc pitch may vary only by one or two semi-tones; at a radical depth it can vary by one or two octaves. If OSC 1 is not modulated, then the OSC MIX essentially assumes the same position as dry/wet mix. At 100% OSC 1 position (dry), no LFO modulation will be heard; at 100% OSC 2 position (wet) only modulated signal will be heard. At 50/50 both signals will be heard. But the depth of that modulation can still vary from semi-tones to octaves within that framework.

But Tremolo is not pitch modulation, only amplitude (volume) so the dry/wet signals will only differ in volume. Mixing them makes it the same as depth of the effect (within a range).
For pitch and filter modulation effect I agree with Pablo that it will be different, but for volume, I do not think so.

[pablomastodon]

Sorry Mr. G, but I have to disagree. Yes, tremolo is not pitch mod, but the principle behind it is the same -- I spoke of pitch mod only because it works better as an illustration.

Effect depth in terms of tremolo will denote the difference in volume between the high volume point and low volume point. The volume level oscillates smoothly between those two points according to the rate set. If this effected signal is mixed with noneffected signal, the overall volume floor will be higher but the depth of oscillation will remain the same as it was prior to mixing. If I had the ability to produce graphs, this would be easy to show...

Wooow !
I understand things much better with your answers ...
So now I guess I'll have to try that with a Pedal to ear exactly what it does affect.
The mix of a fixed rate or ... the depth of itself (I don't know if i am very clear myself but i unsterstand the concept).

I guess that is not easy to hear the difference sometimes ....

Between giving more importance to a signal with 100% trem instead of the one at 0% and lets say, go from 0% to 100% with the pedal ... hard to hear the difference ... no ?

That's how I undestand it with my poor english

Cheers

Yes, you get it 'offset' from the dry signal, but only if the signals are summed. Here I am assuming that the mix function is not just "adding", but mixing/balancing (so the dry signal goes lower volume as the wet increases) otherwise the mix would change overall volume as you go from one to the other? That is what I meant by "rescaled".
Try it in the NS2 with 2 pianos and change the slot volumes. It is impossible to tell if you have a single piano or a mix of one dry and a wet piano.

Disclaimer: of course I do not know what goes on in the circuitry and also I have been wrong before!

[pablomastodon]

ah yes, Mr. G, you are correct about the balancing of the two signals to result in even volume. I forgot about that and was lost in theory.

The thing here with tremolo is that it is generally so subtle that with most common settings it would be hard to distinguish between changing depth and changing wet/dry mix. Again, my brain was looking only at theory and not so much at practical application, where you are 100% right.

Fine that the great minds finally agree!

Enjoy the control over your effect in playing, everyone!
