Introduction

The C15 is an instrument for the performing musician, designed for playability and detailed sound editing. Its unique sound character ranges from crisp and organic to complex and experimental. The top-quality semi-weighted keybed drives a digital synthesis engine which responds with a wide spectrum of sound colors and intensities.

As a dedicated real-time instrument, the C15 is built for human control. There are no modulation sources or sequencing modules to create rhythmic patterns - we leave this to the musician. Instead, the C15 is a decidedly responsive instrument which combines high-resolution keys, ribbons, and pedal inputs.

Almost every parameter on the C15 can be selected directly by pressing a button. In other words, while all functions are software-defined, they have a dedicated haptic control surface. In addition, a User Interface is available, which can be displayed and edited on any device with a browser application and Wi-Fi. Like many classical instrument builders, we have chosen wood for most parts of the housing. All other parts are made of steel or aluminium. Along with the excellent keyboard with monophonic , there is a specially-designed ergonomic (pitch) , two very long (touch-strips), and inputs for up to four .

About this manual

The following chapters refer to different important aspects of using the C15. Each chapter excludes the broader picture by focussing only on the crucial related aspects.

Nevertheless, the manual attempts to cover as many details as possible. When you use the manual, it is best to be sure you have identified the subject you are interested in before you look something up. The following overview explains how the manual is structured:

Setting up the C15

Please read this chapter before you assemble the C15's components for the first time.

Basic Concepts

This chapter outlines the general approach to the C15, explaining how to perform with it, how the modulation mechanism works and how everything is organized.

User Interfaces

This chapter explains how to actually use the instrument. The navigation methods, editing and access to presets are described in detail for each available interface.

The Synthesis Engine

All signal- and DSP-related aspects are covered in this chapter, including details on signal synthesis and flow, tutorials, and details on the integration of Sources.

Recorder

This chapter explains the Recorder feature of the User Interface.

MIDI

This chapter explains the MIDI features of the C15.

Setup (C15 System Settings)

When you have already gained some familiarity with the instrument, the setup chapter provides insight into the C15's advanced system settings.

Keep in mind that the HTML Manual provides some external links to the web, such as the Nonlinear Labs download section, for example.

However, these links will only work when an internet connection is active, which is usually not the case when accessing the HTML Manual by using the C15 UI (because the connection is already in use for the Wi-Fi hotspot, provided by the C15).

When connected with the C15, a second Wi-Fi adapter can be used in order to access the internet from the mobile device in parallel.
