NAMM 2019: New Modules from 2hp

We at CatSynth are fans of 2hp, and not just The Cat. They’ve given us so many things to put in those pesky little spaces left in our modular systems, from highly useful VCAs (you can never have too many VCAs), to more exotic offerings like physical modeling.

At this year’s NAMM show, the debuted four new modules covering both utilitarian and creative terrain. The one that most intrigued me was the Bell, a physical modeling voice that brings metallophone sounds. It can do vibraphone-like sounds, wine glasses, bowls, and of course, bells. With the main mallet and bar parameters (indicating that is likely based on modal synthesis), one can get a variety of combinations with CV modulation. This looks like a lot of fun – I already on the Pluck – and look forward to its release.

At the other end of the spectrum is the DC module. It offers three different DC offsets along a -5v, +5v, and 10v scale. These are useful utilities when crafting specific CV signals. I could see this pairing nicely with a Make Noise Maths for more precise control, or for tuning 1v/Oct controls.

Next up is the Sine, which is more than a simple sinewave generator. It does have a pure sine wave, but also a sub that allows blending of the fundamental, one octave below, and half an octave above. It also includes a wave folder function for rich harmonics. Essentially, this is another harmonic oscillator.

Finally, there is the Grain, a granular processor that buffers incoming signals and allows them to be output using granular synthesis. This is a bit different from a sample-based granular module like the original Nebulae from Qu-bit which works on stored samples (the v2 of the Nebulae does allow processing of live input). The buffers can then be mangled and stretched by setting the density and periodicity of grains, along with the overall pitch. The demo we saw had this hooked up to The Cat.

The result of the new modules plus the Cat and percussion made for a delightful demo as you can see and hear from our video.

Owlsynth Pics for Superb Owl Day

We at CatSynth feel there is no better way to celebrate Superb Owl Day than with “owlsynth pics”. Here is our stuffed owl atop our main modular system.

And with our trusty Roland Boutique VP-03 vocoder.

And with our Arturia MiniBrute 2.

(Definitely need to tidy up a bit there.)

Owls are quite captivating as they are so different from other birds, even from other birds of prey. We all know their unique front-facing faces and nocturnal behavior. But they also have amazing auditory capabilities.

From Owls and Hearing – The Owl Pages

Both the cat and the Barn Owl have much more sensitive hearing than the human in the range of about 0.5 to 10 kHz. The cat and Barn Owl have a similar sensitivity up to approximately 7 kHz. Beyond this point, the cat continues to be sensitive, but the Barn Owl’s sensitivity declines sharply.

Some Owl species have asymmetrically set ear openings (i.e. one ear is higher than the other) – in particular, the strictly nocturnal species, such as the Barn Owl or the Tengmalm’s (Boreal) Owl. These species have a very pronounced facial disc, which acts like a “radar dish”, guiding sounds into the ear openings. The shape of the disc can be altered at will, using special facial muscles. Also, an Owl’s bill is pointed downward, increasing the surface area over which the sound waves are collected by the facial disc. In 4 species (Ural, Great Grey, Boreal/Tengmalm’s & Saw-whet), the ear asymmetry is actually in the temporal parts of the skull, giving it a “lop-sided” appearance.

We at CatSynth hope you all have a fine and enriching Superb Owl Day!

NAMM 2019: Qu-Bit Electronix

One of our first stops at NAMM 2019 was to visit our friends at Qu-Bit Electronix. This year they had three new modules to share.

The first of the three was the Prism (center in the picture above). It combines three audio processors that are mapped to a three-dimension “prism” control space. One axis controls a comb filter, another a bit crusher, and the third is time/speed control. The audio processors operate on a buffer, which can either be continuously updated from audio input or “frozen” in time and looped. Finally, there is a multi-state filter that can either operate at the beginning or end of the signal chain. Of the three, this one perhaps intrigued me the most with the possibilities of mapping these different functions to CV input (e.g., from a Maths or a sequencer) in ways that push traditional music. You can hear a bit of it, along with the other two modules, in our video which features all three modules.

The second module was the Chord, or rather the new incarnation of the chord. It’s a four-voice polyphonic oscillator with both traditional waveforms (continuously morphable) and a new set of wavetables. The oscillators can be stacked into chords, or in this new version each controlled separately for polyphony in the music-theory sense of the word – yes, with the right sequencer, this module can do four-voice counterpoint. The chord mode includes a variety of standard western four-voice chords (i.e., with a seventh degree), but also the ability to add custom chords that include microtones or dense tone clusters. It’s also more compact than the original, slimmed down to just 14hp.

The final module was the Bloom, a sequencer that could generate variations on the fly using a proprietary fractal algorithm. The amount of variation, from none to completely random, can be controlled dynamically via CV, as can the number of steps in the sequence, for quite a range of variety. And with two channels, it would seem to pair nicely the Chord.

As always, it’s fun to visit with Qu-Bit and see what they up to, especially as they are CatSynth superfans. And we look forward to seeing these modules out in the wild over the course of the year. The Prism is due in March, the Chord in late spring, and the Bloom in the fall.

NAMM 2019: Korg Volca Modular and Minilogue XD

We can always count on something new from Korg these days. Sometimes it’s completely new, but this year it was new incarnations of existing lines. We introduced them in a recent CatSynth TV episode and describe them in more detail below.

The Volca series continues to grow with its newest offering, the Volca Modular.

Korg Volca Modular

The Volca Modular is a self-contained semi-modular synthesizer in a tiny volca-sized package. It has a VCO and modulator for complex waveforms, a function section with envelopes and an LFO, a sequencer, and various patch points for splitting and mixing. Its novel element is the LPG, a low pass gate that can be used as an amp, a filter, or something completely different a la west-coast synthesis. It puts quite a lot in a little box for just $199.

It reminds a bit of some other “tiny tabletop semi-modular synthesizers” such as the Moog Werkstatt or the newer Bastl Instruments Softpop (my CDP bandmate Tom Djll uses one of these and thus I want one, too). Like those, the Volca Modular has tiny little patch points and chords, which are adorable. But unlike those, I found it difficult to patch. The wire tips were a bit flimsy and I bent at least one of them trying to create a new patch on the fly. Otherwise, though, I think this is a fine little instrument, and could end up in my Volca collection.

Minilogue XD

The other new instrument was the revamped Minilogue XD. The original Minilogue made quite a splash a couple of years ago as an affordable polyphonic analog synthesizer. In addition to a nice, darker finish, the XD adds their expandable digital wavetable technology from last year’s Prologue. The digital engine has several different oscillator types and functions, and is essentially a “third sound source” for the instrument. It’s not clear to me whether this includes the same open API that the Prologue has, which would be an unfortunate omission for us at CatSynth, though probably not an issue for most users. It also has microtonal capabilities, something which is missing from many structured MIDI-analog combinations.

Both of these instruments are interesting, incremental changes, with Korg seemingly defending the turf it established in the synthesizer resurgence. Neither is a top priority for us at CatSynth, but I would be surprised if they find their way to us at some point.
