Two identical frequency sweeps (30hz - 60hz) resonate on two slightly different elevated asphalt slabs.

Each sweep is a 10 minutes long, loops for 70 minutes, and start 5 minutes apart from each other.

the sound fades in for 50 minutes, and fades out for 20 minutes.

on a small slab a oscillator plays a random low tone on a constant low volume.

the resulting sounds reverberate in the W139 galerie's huge exhibition room in the center of Amsterdam, NL

Two frequency sweeps & one oscillator on elevated asphalt floor, janitor cleaning on the background

Born out of some improvisation with my Korg Montron combo, an original Monotron and a Monotron Delay. The basedrum you hear (and the noisy hihat-ish sound in the background, which is just a filtered version of the original) is the filter of the Monotron self oscillating, fed through the Monotron Delay and then recorded and looped in ableton.

The grit of the Monotron Delay gives the whole thing a lot of character, quite typical for dub techno beats.

Originally the thing (as it was an LFO fed filter sweep) was straight four to the floor, but I decided that this was not what I had in mind and I built a drum rack out of different parts of the original beat filtered to the desired frequency range.

The dub techno stab is a sampled single shot played with the Monotron (also fed through the delay, which creates these weird off beat sounds) turned into a proper stab using simpler, an auto filter, a ping pong delay and a reverb (and some EQ for good measure).

The bass sound uses an Ableton Simpler with the exact same sample looped and filtered.

The synth effects are pure Monotron Delay, freely recorded and then somewhat chopped up and put into place.

Starts off clean, then just BOD, then Bod>Oxide, then all three.  I'm using a Moog EP2 expression pedal to control the frequency sweep on the Xerograph.

Settings:

Oxide: EQ-3 oclock, Morph-9 oclock, Drive-8:30, Fuzz and Clean equal...voice and strangle down

BOD:  75% growl to clean

you can expando your Analog Four´s tracks adding a synth kick drum that use one of the CV outs

just traget the DC level with an audio-rate, sine LFO...then use one of the envelopes to control the LFO´s rate (kick frequency sweep) and the other to control the LFO´s amplitude (kick volume)

SINE KICK USING THE CV CHANNEL

hi all

first in (possibly) a few blind tests of my various filters

 not exactly laboratory conditions, but may be interesting nonetheless

just a simple AFG tone (saw sub and pulse) into each filter in turn, with six sweeps through the frequency range with increasing resonance.

I have used a 24db (4 pole) LPF wherever possible, but it was impossible to match all the filters by mode, as some don't have 24db and some don't have 12db. 

i have matched the cutoff as much as i can, and the range of the sweep.

i have also tried to get MOST of the different tones of resonance in - up to just before self-oscillation (if the filter does this). this is because self-osc tends to completely take over the sound otherwise, and jumps out at ridiculous volume...making for a fatiguing listen when comparing. All recordings have been normalised, but there may be differences in perceived volume due to peaks when at high resonance.

i have also tried to set each filter for pretty much its cleanest setting (some have input gain which drives the filter into a more overdriven tone - i'll feature some of that in the later audio files i reckon....if i don't get bored by then!)

so......

there are the following filters in this test  (in alphabetical order):

Blue Lantern Diode 
Blue Lantern LM4250 Polivoks Clone
Doepfer a124 Wasp 
Cwejman S1 Mk2 LPF 
Cwejman S1 Mk2 MMF 
Pittsburgh Modular Filter 
Tiptop Audio z2040 
Vermona Retroverb Lancet's Filter

not sure how easy it is to tell them apart in this particular test, but it's somewhere to start. will do a few more different ones i think...
