2.2. Creating your first core cell You create new core cells by right-clicking on the background in a primary-level structure and selecting Core Cell > New Audio or, for event cells, Core Cell > New Event: We are going to build a new core cell from scratch inside the same One Osc.ens you already played with. We will be using the modified version of that ensemble with the new oscillator and chorus that we built in the last chapter, but if you didn’t save it don’t worry, you can do the same steps using the original One Osc.ens. As you can see, in this ensemble we are modulating the filter at the P input, which accepts only event signals. We are not using the FM version of the same filter because it does not perform as well at higher cutoff frequencies, and because the modulation scale is linear at an FM input, which generally gives less musical results when modulated by an envelope. (That phenomenon is typically but incorrectly referred to as “slow envelopes”.): Because we need to apply the modulation at an event input, we also need to convert the envelope’s output to an event signal, which we do with an A/E 24 – REAKTOR CORE
converter. As a result, our control rate is pretty low. Of course we could have used a converter running at a significantly higher rate (and eating up significantly more CPU), but what we are going to do instead is replace this filter with one which we build as a core cell. Alternatively, we could have taken an existing filter from the core-cell library, but then we would miss all the fun of making our first Reaktor Core structure. We’ll start by creating a new audio core cell. Select Core Cell > New Audio and an empty audio core cell will appear: Double-click it to see its structure, which is obviously empty. As you surely remember, the three areas are meant for input, output, and normal modules: REAKTOR CORE – 25
