SYSTEM-LEVEL PARAMETERS AND OBJECTS At the bottom of the main window, you’ll see system-wide parameters which affect the entire operation of the Isle I-1.  All system-level objects and parameters, including the entire MIDI configuration and tuning system selection, are saved as part of the Patch Bank file – you can have totally different system setups […]

KEYBOARD SPLITS In a given setting, you may want to remap the keys of your keyboard, and divide the keymap such that different ranges of keys play sounds from different patches.  The Isle I-1 allows this, and takes the idea a couple of steps further, via a special kind of patch called a Keyboard Split.  […]

EFFECTS The Isle I-1 ships with a large collection of onboard effects, and that collection is constantly growing.  Effects can be wired into a sound in several places.  In each spot, effects can execute in series or in parallel, or both.  Many effects can operate on multiple channels of input, and with a huge and […]

ENVELOPES, FREQUENCY RAMPS, AND VALUE RAMPS Envelopes, Frequency Ramps, and Value Ramps are the mechanism for precisely varying a value over the duration of a sound.  As a developer, it bugs me to have 3 different names for the same underlying object, which they are, under the hood.  The names, however, reflect the specific cases […]

ADDING MODULATION TO AN OSCILLATOR One of the most important goals in the design of the Isle I-1 is to allow total freedom in designing modulation algortihms.  Rather than stick you with a hard-coded set of algorithms with a fixed number of operators, you can build absolutely any algorithm you can dream up, with the […]

THE PATCH The Patch is the basic template for producing a timbre, regardless of frequency/pitch.  A new Patch Bank comes with a single Patch, with a single Oscillator set to generate a sine wave.  You’ll probably want something more interesting than that — this chapter describes how to add additional Oscillators, add Modulators, and change […]
