R esonant Filter Collection
(and still SEM after all these years)
3 Classic Resonant Hardware Filters: MINI, 2600, Juno: 24dB, 6dB & Mix—a customized
blend of the Juno types. Put them to work in Paraphonic Mode and behold the Glory.
FREQUENCY
The lower the cuto ff frequency, the less harmonic content the waveform will retain after
passing through the fi lter. A wave shape rounding and smoothing also occurs as this
cuto ff frequency is reduced. Play, sequence, trigger a note, and harmonic content
produced above the cuto ff frequency is reduced by the fi lter on a 24/12/6dB per Octave
slope; MIX Mode, which resembles a bandpass meets hipass meets band reject fi lter,
features a slope value of great mystery and suspense.
MODE SWITCH & MINI POT
When the MODE switch is pressed/lit the rotary switch setting determines the Resonant
Filter in circuit: Mini, ARP™ (2600), and the 3 Roland™ (Juno) modes. Unlit, the boxy,
boomy SEM
fi lter of “Basic Record” built into the voice board is working its 12 dB alchemy.

RESONANCE
The resonance, or “Q,” emphasizes, or boosts the cuto ff frequency region, making the
presence of harmonics more apparent. Self-oscillation for our Resonant fi lters happens
when the knob passes the 3 o’clock position, resulting in a pure sine wave—use as a
separate unique tone source; it will track reasonably well over several octaves with
TRACKING at 10. Resonance is in fact positive feedback—a ubiquitous and signature
sound of subtractive synthesis. Note: The SEM fi lter does not self oscillate.
TRACKING
Applies keyboard CV (control voltage) to the fi lter. The more tracking used, the brighter
the sound will get as you ascend the keyboard. Maximum tracking is 1 v/octave.

Why all these filters (Maestro Greg St. Regis is asking you)?
The Resonant Filter Collection is a rich representation of history's most popular subtractive synthesis discrete filters: the creamy,
boomy depth of the Mini, the grunge and mid-range character of the 2600, and the clean crisp energy & resonance snap of the
8106, with its 6db and 24db outputs—those two additional modes combine in MIX (#3) for a snarl and bite you’ll soon wonder how
you lived without ;) There are mainly subtle di
ff erences between the Mini, ARP, and 8106 (Juno/Jupiter), but it is in the subtlety
wherein lies the magic. They all benefit from three discrete warm oscillators flowing through their circuits to pass, ultimately,
through a dual stage MiniMoog VCA, adding its own unique vintage coloration. Press all three Oscillators and waveforms into
service; push the resonance settings into chirp nirvana… a myriad of soul-calming, energizing harmonic timbres will come for you.
Switch in the overdrive, either soft or hard, for perhaps the most satisfying part: rich full bodied harmonic distortion/saturation
that pumps sub-harmonics and compresses sagely. The SEM filter is always there for you to take a break from that resonance life
and go lo-mid aggressive and boxy. Five unique authentic filters—there's never a dull moment. In early tests, R3 (the combo mode
of the 8106 filter) is turning out to be a fan favorite. What will be yours?
