The SEEDS is a complex powerful 8 bit oscillator and can be used as a complete synthvoice.On the sound-design side you might notice some 90's popular music influences. There are two reasons for that. First of all; those sounds are a natural match for the rather modest (8 bit, 16MHz) Atmel chip on the Arduino Nano we're using. That music was made using digital synthesizers using the processors available at the time, and those had to make the most of the chips available at the time, which were quite comparable to the Nano. The second reason is that those sounds are a lot of fun. Once that link became clear it became more a of a guiding principle than a potential problem; it seems more sensible to lean into such links than it is to resist them.The Arduino in the SEEDS kit is already programmed, but in case you need to re-install the firmware you need the Arduino IDE installed on your computer and install the CH340 driver to communicate with the Arduino Nano. The latest Arduino IDE can be downloaded from the Arduino website: https://www.arduino.cc/en/main/software The CH340 driver can be found here: https://sparks.gogo.co.nz/ch340.htmlThe firmware will be updated regularly so you might want to keep an eye on it to get fresh sounds in your SEEDS every now and than.Features:• The original “Grains” sound.

The Omen is a dual LPG with a bit more than you might be used to. Like you, I once was lost in the world of low pass gates, seeking something more, something bigger and somehow juicier. The inspiration came to me as I was reading a particularly heavy book on passive filters, and I realized it was possible to make far more interesting LPG designs than the standard we've become so accustomed to.In a convergence of old-school LPG design and more modern components, the Omen boasts two -6dB resonant filters, custom built vactrols, built in CV attenuation and no less than three cutoff modes per filter. Filter 1 is soft and light, imparting a gentle, naturally gated touch of filtering on your sound, while Filter 2 is darker and more resonant, and can turn downright growly and distorted when left wide open.Designed to give you as many creative options as possible, the Omen has the unique ability to function as either two discrete LPG, or as one 4-pole resonant LPG. When plugging a signal in to Input 1, and with no signal plugged into Input 2, the output will be present at both Output 1 and Output 2, with Output 2 producing the signal as it passes through both filters. Tweaking both filters independently will generate a wide array of soft and sometimes harsh tones, ranging from Buchla bongos to early synthesis brass and organ sounds. There is much to love here.CV is similarly handled, by plugging in only one CV source, it will act on both channels - this is useful for creating musically similar outputs as well as when using the dual filter operation. However, the dual filter mode greatly benefits from having two CV inputs: use an envelope in CV1 to act as a VCA, and an LFO in CV2 to create tremolo, for instance.Using custom designed, hand built vactrols, care has been taken to mitigate the less desirable aspects of passive LPGs - in most modules, the user can expect zero bleed through on the LPG channels, and signal attenuation is minimal even with the 4-pole filter settings engaged. Of course, many of the natural features of vactrols remain, such as subtle memory effect when engaging the vactrol for long periods.DIY enthusiast? Rejoice! The Omen is available as a fully loaded DIY kit - everything you need to build your very own Omen packed in one place, so you can easily build one in the comfort of your own home. It is not a difficult DIY project, an ambitious beginner or someone with experience from a few easy builds can tackle the Omen in an afternoon. The build is all through-hole aside from three SMD components, which are easily soldered by hand due to their large size.Finally, you receive maximum blinkenlights as LED's on the front panel simulate the action of the vactrols, so you'll always know what's going on under the hood. No collection of fancy LPG's is complete without the Omen - add some analog warmth to your signals, today.Features:• Functions both as two discrete LPGs or as one multi-pole filter LPG• A passive LPG without the characteristic signal bleed or input loss• You read that right: each LPG contains a resonant two-pole filter• Comprehensive build guide, complete with picturesDIY-Kit-Type:THT-Kit-1.

HEX row is an analogue dual resonant filter with versatile routing capabilities, sidechain/envelope follower and mischievous character, stemming from (mis)use of transistors as variable resistors in the signal route.There are two channels, each controlled by three potentiometers: GAIN (2), RES (3), FREQ (4) and sidechained by CENTER (5). Both channels have the same topology. Inputs •| and |• are fed into each channel’s gain stage and then passed to their filters. The input signal level can be adjusted by setting the GAIN which can either attenuate or amplify a signal x20. Note that the amplification affects the filter’s behaviour—high GAIN disrupts self-oscillation, conjuring PLL-esque harmonics and other sound design artefacts. FREQ and RES are used to manipulate individual filter’s cutoff frequency and resonance. Each channel has a side-mounted switch (6) for selecting low-pass or band-pass filtering. Touch the golden touch pads (1) to manually route the flow of audio and control voltages.SIDECHAIN – Left channel’s (•I, •O) post-gain signal is filtered and fed into an envelope follower. Envelopes polarity and amplitude are adjusted by using CENTER. The adjusted envelope is then mixed in the right(|•, O•) channel’s FREQ parameter. Left half of the CENTER causes the filter to “duck” and the right half produces a gating response. In the middle position, the sidechain effect is inactive.TOPOLOGIESFEEDBACK – Connect the •O and I• sockets with a jack cable and use O• as the main output. Leave •I unconnected as it’s normalised to O• by default.Alternatively, using stereo cables and a headphone splitter adapter enables the use of •O as output with dramatic stereo field dynamics.SERIAL – Connect the audio source to I• and use the •O as output.Input signals are processed through subsequent channels as •I is normalised to O•. This mode enables the so-called twin peak and auto-filtering.PARALLEL – Connect a stereo audio source into •I or two mono sources to •I and I•.Left and right signals are split into separate channels, processed and output as stereo signal via •O or as mono on both outputs.You will need a soldering iron, solder, pliers, tweezers and some patience. Before you begin the process, make sure you are working on a clean, well-lit surface. Be careful with the components, some of them are very small—take them out of the packaging one at a time, when needed. Most of the tiny SMD components are marked with numbers that match the numbers printed on the PCB. If you are new to soldering (SMD), we recommend watching some online tutorials beforehand.

ASCOLTA is a dual high fidelity input preamp with envelope follower and peak detector output for each channel. Ascolta consist of two individual high quality preamp connected to an envelope follower and a peak detector output.
