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.

NAMM 2017 Apocrypha and Final Thoughts

In this article, we go over a few remaining items from NAMM, and share some final thoughts as well.

The DATA module from Mordax takes the trend of built-in displays to another level. The large color screen displays a variety of functions, including oscilloscope, tuner , waveform generator and clock. It also has quite a few utility signal functions. It seems like quite the useful item for a medium or large modular system. Plus it looks great!

It’s a common problem with modular synthesizer systems to end up with 2hp empty and nothing to fill it with, except maybe a branded plate. 2hp quite literally fills this niche with a large selection of functional modules exactly 2hp wide.

We could all use extra multiples, or another envelope generator, or VCA. But their 2hp offerings include oscillators and filters. We could see these in various cases to get some handy functionality when needed.

Delptronics has made quite a few modules for percussion synthesis as well as for complex triggering of other modules. Their product line has grown; and we were particularly curious about the new spring module an its electro-acoustic possibilities.

We are always curious to see what 4ms has to offer, as the Spectral Multiband Filter has become one of our favorite modules for a variety of musical purposes. Their new offerings this year included a sampler module and tappable delay, which are shown in the upper right of the following photo.

There was of course more at the modular super booth and in the neighboring booths beyond what we have been able to cover this year. It will be inevitable that some products and manufactures don’t get mentioned in the blog, though we do have more on our Instagram feed during the show. We will have to figure out if there are any logistical changes we might want to try next year in order to see more while still remaining authentic and having the fun time at NAMM that we always do.

The trip home, despite the pouring rain and flooding in the LA Basin, ultimately turned out to be a pleasant one. I suppose I had a bit of a glow from the show, and full of ideas on how to move forward musically and personally in the challenging times ahead.

Even with the literal rainstorms outside and the dark pall cast by the political situation, inside the convention center we were all able to be ourselves and follow our passions for music and music technology. That doesn’t mean that outside reality didn’t intrude. It was impossible not to despair a bit on inauguration day; and by contrast Saturday with the Women’s Marches gave a bit of optimism. Mostly, I just kept doing what I came to NAMM to do. We hope you have enjoyed following our coverage, and we’ll be back doing it again next year barring some world-changing catastrophe (which unfortunately could happen).
