Resonance. Evolver’s LPF has another important parameter called “resonance”

Evolver’s LPF has another important parameter called “resonance”. Resonance emphasizes the filter’s character by creating a feedback loop — the output of the filter is fed back into its input. Resonance is so named because the feedback is similar to the filter “resonating” at its cutoff frequency.

On other synths, including the legendary MiniMoog, LPF resonance may be called “emphasis” because it emphasizes the filter frequency and sound.

The higher the value of the resonance parameter, the more signal is fed back to the filter.

Adding resonance emphasizes the filter’s character. Lower levels can provide a very funky “honky” or “quacky” sound.

Let’s try it out. Bring up the basic patch (I hope you’re not sick of it yet!).

Make the following changes:

• OSC 3 and 4 Level = 0

• Mod Wheel Destination = rES (resonance)

• Mod Wheel Amt = 99

• Filter Frequency = 95

• 2/4 pole = 2 P (2-pole)

Play a note — middle C or lower. Hold it down, and start moving the mod wheel around. Try some very low and very high notes.

Do it slowly, so you can hear the filter’s effect on the timbre as the value changes.

Now, let’s see what happens with 4 pole mode. Change the 2/4 pole setting to 4 P (4-pole). Turn the mod wheel all the way down.

Если нет колеса модуляции, просто найдите параметр Filter Frequency на Evolver и поверните ручку.

Теперь попробуйте его с фильтром в 4-полюсном режиме вместо 2-полюсного. Слышите разницу?

Попробуйте также разные ноты.
