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.
