Choose between the original "Classic" filter (left), which faithfully emulates the famous 24dB ladder filter from Moog, or a new "Modern" filter (right). We designed the Modern filter to have the same tonal characteristics as the original, but it maintains bass frequencies better when using emphasis.
<aside> 📖 While the Moog 24dB Ladder filter is a legendary thing of genius & joy, over the years one of our slight frustrations is that the moment you turn that resonance up, it starts to attenuate all that lovely bottom end. This second filter is an attempt to address that via a different Emphasis curve and Gain structure.

The original Minimoog and Minimonsta had 3 stage ADS envelopes, with the option to control release time via the decay knob and a decay button (See Global Controls). We’ve kept that original behaviour, but added optional ADSRs with separate decay and release times via this switch.
<aside> ⚠️ This switch controls both Filter and Amplitude envelopes. You cannot have one type for the filter and the other type for amplitude.

This knob attenuates, or cuts out, frequencies above the cutoff point, while allowing those frequencies below the cutoff point to pass through. When the knob is turned all the way to the right, all frequencies pass through and no filtering occurs. However, when the knob is turned all the way to the left, the entire signal is cut off.
This is also known as resonance or Q and effectively adds emphasis at the cutoff frequency. When pushed to ranges of around 7 and above this will introduce a sine wave at the cutoff point.
This determines the amount of filter envelope applied to the cutoff frequency. The shape of this envelope is determined by the filter attack, decay and sustain settings.
This knob determines the initial fade in (or attack) of the filter envelope. Times can vary between immediate (1 millisecond) and long (12 Seconds)
<aside> ⚠️ In ADS mode, the attack phase starts from where the filter decay phase ends, allowing the cutoff to "climb" higher with fast repeated notes. This is authentic to a 70's Minimoog.
</aside>
This determines the time the filter envelope takes to fall from its initial peak to its sustain level. Times vary between 8ms and 48s.
This knob determines the level at which the filter envelope levels off after the initial rise (attack) and fall (decay).
