g-storm electro sh2-vcf & electro tonus vcf filter explorations

Published on Mar 15, 2020 impurfekt

http://gstormelectronica.blogspot.com/

"please support the channel: https://impurfekt.bandcamp.com

the g-storm electro sh2-vcf is a 24db/oct filter based on the roland sh-2 bass synthesizer from 1978. it's the epitome of the roland sound and ranges from sweet to dirty depending on how hard you hit it.

i owned g-storm's v1 version of this filter in the past and missed it. this is the v2 model and is sonically identical as far as i can tell. it's got all the features you'd expect and is a joy to use. it's very smooth with no resonance (great for subtle arps) and has a lot of character with resonance. not many filters in my bank can pull that off.

arps begin at 6:40

g-storm electro tonus vcf filter exploration

Published on Mar 15, 2020 impurfekt

"the g-storm electro tonus vcf is a 24db/oct filter based on the original arp 2600 4012 filter. the 4012 was arp's moog clone filter that was later revised due to patent infringement.

i've neither seen nor heard a 2600 in person, but the tonus vcf is certainly in the ballpark of demos i've heard and other filter clones i've used. its tone is warm, fat and vintage. the harder you drive the filter, the better it sounds. the front panel is roomy and well laid out. i look forward to further exploration; especially for bass duties.

arps begin at 4:28

"please support the channel: https://impurfekt.bandcamp.com

this is the matrixbrute. it is an analog synth with dual filters and a unique voice architecture. it is huge (takes up the whole desk) and one of the best synths i have ever heard.

both the drums and lead are being generated in real time using the duo split mode and built in sequencer. the delay is an on board analog bucket brigade stereo delay.

audio is raw from the synthesizer. turn it up and bask in the glory. you'll be hearing more of this beast in the future."

doepfer a-124 vcf5 wasp filter

impurfekt

"please support the channel: https://impurfekt.bandcamp.com

the doepfer a-124 vcf5 is a 12db multimode filter using the filter circuit of the edp wasp; an analog synthesizer with a black and yellow case built in the seventies. this filter abused digital inverters as analog operational amplifiers leading to distortions and other dirty effects that generate a unique character. it's equipped with a band pass output and a combined low/notch/high pass output.

once i had gathered the filters i was familiar with i started exploring other options to expand my palette. after seeing a few demos i was very intrigued by the wasp filter. it reminded me a bit of an ms-20 filter but with its own brand of nasty. in person the wasp did not disappoint.

the layout is nearly identical to a few other doepfer options which made it easy to pick up and play. it has the mid-forward tone you expect from a 12db filter. high resonance is nasty and unpredictable but won't blow your speakers (which is nice).

where this filter really shines is when you overdrive it. it sounds like a different version of itself; nice and smudgy. you can get away with high resonance and still get an even sound level; which means you can use high resonance in a lot more situations. in that way it reminds me of the korg prologue filter (another filter i adore).

i appreciate a filter with a broad range of character and the a-124 definitely has it. i wouldn't say it's as musical as a moog or roland filter, but it has a very usable range of nasty and can make unique sounding bread and butter sounds as well. a great option if you're looking to add something unique to your toolkit.

mopho x4 + walrus audio d1

impurfekt

"please support the channel: https://impurfekt.bandcamp.com

using the mopho x4 to explore every nook and cranny of the walrus audio d1 delay pedal (straight out of the box).

the walrus audio d1 is a digital delay pedal with stereo in/out, midi in/out, preset storage and five unique algorithms. it is the first in walrus audio's "mako" series of high-end pedals. the algorithms cover the essential delay styles and respond uniquely to the age and tone settings.

all the features i want on a delay pedal are here. the tone and character of the algorithms are as good as any i've heard (both analog and digital). the pedal is easy to use, well labeled and well built. definitely a new favorite. highly recommended for those seeking tone above all else.

dave smith instruments curtis filter exploration

Published on Feb 26, 2020 impurfekt

"please support the channel: https://impurfekt.bandcamp.com

the curtis filter module from dave smith instruments is exactly what it says on the tin; an authentic curtis filter for eurorack. it has both -12db/oct and -24db/oct settings as well as a +6db boost and an internal vca. here i explore it using the mfb vco/dco oscillator.

having a mopho x4 in the studio (and absolutely loving it) i'm quite familiar with the curtis filter sound. this module doesn't disappoint. it's raw, dirty and loves to resonate. it can sound smooth with the right source as well. during this session i was surprised to find it reminding me of the korg ms-20. it definitely lands in similar territory. i'm looking forward to doing some dark sci-fi work with it.

malekko manther growl exploration

impurfekt

"please support the channel: https://impurfekt.bandcamp.com

the malekko manther growl is a synth voice for eurorack based on their manther desktop synth. it includes a cem3340 vco chip and an ssm2044-based analog filter. it has separate levels and outputs for the square, saw and triangle oscillators. it has two adsr envelopes with outputs and an lfo with multiple destinations and an output. it has a wavefolder with two modes: tri or all. the all mode folds all waveforms and the external input post-filter.

i've had my eye on the manther desktop for some time but knew i wouldn't utilize the built-in sequencing capabilities. upon discovering the manther growl i realized i could replace a number of modules in my existing rack (including my a-105 vcf which is based on the same ssm2044 chip) with room to spare.

after spending a few hours with the manther growl i'm very impressed. it's straightforward and sounds as good as the specifications suggest. the filter has a nasty, vintage character. the oscillators are beefy. the wavefolder is a unique addition that introduces unpredictable sonic variety. all the tools i like in a single oscillator synth are there.

my only critique is that driving the levels doesn't seem to alter the tone. the manther growl sounds as though it's always being driven. that said, it's still capable of subtle sounds. what it excels at though are thick, heavy, nasty, dirty tones. in short, it does what is says on the tin.

it's time to explore the walrus audio fathom reverb pedal and show you why i use two of them.

utilizing the bass station II i first explore every parameter on one fathom. i then run the signal through both and hopefully convey the possibilities and advantages of running two mono reverb pedals in parallel.

emw multiwave digital oscillator part I - wave analysis

Published on Dec 28, 2019 impurfekt

"please support the channel: https://impurfekt.bandcamp.com

the multiwave digital oscillator from emw has 40 main oscillator waveforms and 8 sub-oscillator waveforms. it uses a multi-algorithm structure to produce dynamic waveforms (as seen via the oscilloscope). synthesis methods available are: wavetable modulation, fm, wave distortion, formant shifting, timbre stretching and windowed sync. the sound palette on tap is staggering.

this video shows each waveform and how they respond to the wavefolder knob. part II will feature musical examples."

bass station 2 + dd-200 - deep dive

"please support the channel: https://impurfekt.bandcamp.com

using a saw + triangle patch on the bass station 2 to explore every nook and cranny of the boss dd-200 delay pedal.

the dd-200 is a digital delay pedal with stereo in/out and a multitude of algorithms. it is essentially a simplified dd-500 with knob-per-function control. the algorithms sound smoother to my ears but i no longer have a dd-500 for a side-by-side comparison.

this was a lot of fun. i may make a habit of it.
