Attack Synth – based on the Korg
®
X911 Guitar Synth.
We borrowed the unit that inspired this model from the delightful and delicious Eric Dover (of Jellyfish and Imperial Drag). Your
Filter Modeler’s Attack Synth uses a waveform modeled after one of those in the X911, along with some of the wave shaping
functions that are found on the original X911. FREQ controls the stop frequency of the filter (labeled VCF on the X911). Q
selects between Square, Pulse Width Modulation, and Ramp for the synth waveform. SPEED controls the Attack (sets the time
it takes to get to the stop frequency). MODE controls Pitch over a two octave range.
Synth-O-Matic – inspired by a collection of vintage analog synths.
This model features waveforms captured from a mouth watering collection of vintage synths: a Moog Modular (which is the unit
pictured on the right), Oberhiem Synthesizer Expander Module, Sequential Circuits Prophet 600, Arp Explorer-I Model 2900,
and Studio Electronics SE-1 – groovy analog circuitry giving its all to make mind-warping waveforms. FREQ sets the frequency
of the filter, which determines how bright your sound will be. Q sets filter width to add more or less additional emphasis on the
selected frequency. SPEED selects one of the eight synth waveforms. MODE controls the Pitch of the synth sound.
Octisynth – inspired by eight armed denizens of the deep.
Everyone knows that all you need is a bottleneck and a reverb tank to get great whale sounds, but how about our often-ignored
deep sea friend the Octopus? To emulate the call of the famous invertebrate, we’ve provided you with a subtle, velocity sensi-
tive combination of Ring Modulator, Synthesizer VCO and Vibrato pedal. Your guitar’s volume knob gets in on the action by
controlling the frequency of the oscillator. Set it low to mimic the large Octopus dofleini of the North Pacific, or turn it all the
way up to communicate with the inch long Octopus micropyrsus. FREQ controls filter content, adding second order harmon-
ics. Q controls the width of the filters, from mild to wild. SPEED sets the rate of the Vibrato. MODE controls the Depth of
the Vibrato.
Slow Filter – it’s Swell!
This triggered filter rolls off the high end of your tone, with adjustable speed. You get a choice of having your tone sweep from
dark to bright (the UP mode), or bright to dark (the DOWN mode). The Q lets you further shape your tone by creating a
sharp boost at the point of the high end roll off. Just plug in your guitar or other noise maker and you’ll see soon enough what
we’re talking about. FREQ sets the frequency where the filter begins its tone shaping roll-off. Q controls the width of the filter.
SPEED sets the speed of the filter sweep. MODE selects between two modes: UP or DOWN.
