LoopMangler is an innovative multi-effect glitch sequencer designed to manipulate rhythmic samples, external input, or output from other applications. This powerful tool operates based on the effect sequence patterns, allowing you to transform ordinary loops into unusual glitchy and noisy textures. Key Features: Advanced Sound Design: With its well-designed user interface and creative features, LoopMangler provides an exciting playground for sonic exploration and sound design. Random Pattern Generation: Make patterns and individual bars randomly or according to specific rules, offering a quick start or a source of inspiration for your projects. Multi-Effect Sequencing: Assign up to six distortion and filter effects to each step of the sequencer, providing endless possibilities for sound manipulation. Envelope Modulation: Each effect is modulated with its own envelope generator, ensuring that every step is unique and dynamic. Intuitive Editor: The user-friendly editor allows you to easily copy, move, and delete individual cells and bars within the sequencer, making pattern creation a breeze. Live Pads: Assign presets and loops to on-screen pads and use special pads to dynamically alter sound patterns during live performances or studio sessions. Real-Time Processing: Process audio in real-time, allowing you to hear the effects of your adjustments immediately. Flexible Integration: Seamlessly integrates with other audio applications, making it a versatile addition to your music production toolkit. Whether you’re looking to add subtle textures or completely transform your audio, LoopMangler provides the tools you need to achieve your sonic vision. LoopMangler is a universal application for iOS and macOS. It can work on iPhone and iPad as well as Mac / MacBook with M1 chip (and later). LoopMangler works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, and supports Audiobus and Ableton Link. On MacOS, LoopMangler can works both as a standalone application and as an Audio unit (AUv3) with DAWs and other hosts that support AUv3 plugins. LoopMangler has a built-in detailed description of all parameters also available as PDF file on the application site.

Read full description

FuncBud is an AUv3 MIDI sequencer app that generates sequences using simple math functions. You can create math functions with the function builder, then chain and repeat them to create complex sequences. A simple x + 1 function would sequence all the notes in the scale in order. It gets more interesting when you use different formulas and chain them. The sequencer starts from the root note and evaluates the first formula to calculate the new note. Then, it moves to the next formula. If it's a repeating function, it repeats the specified number of times before moving to the next formula. The formula's result is converted to a note in the working key and scale, within the defined minimum and maximum octaves. This new note is then played. Additionally, the result is stored in a history of up to 64 entries for later sum or product calculations The function builder lets you create functions with simple addition, subtraction, multiplication and division operations as well as square, square root, sum and product operations. You can also use parentheses to prioritize the calculation order. The newly created function will be saved and accessible in the library across both the standalone app and AUv3 instances. With the conditional functions, you can specify a condition like "if this function is greater than that function, then execute the function A, otherwise execute the function B". The random function generator will generate a value between two functions, a function for the lower bound and another function for the upper bound. The sequencer picks the notes in the current key and scale, between the minimum and maximum octaves. You also have a root note, the starting note, which are all defined at the top of the UI. You can use BrainBud to change the key and scale as well. The sequencer speed (rate), gate length, gate length variety, velocity, velocity variety and swing parameters are accessible with the sliders at the bottom of the UI. In edit mode, you can change the order of the functions. You can also delete a function in edit mode, or simply by swiping it to the left. Newly created patterns automatically copy the current one, making subtle changes easier. If you prefer a clean slate, you can quickly clear the list with the clear button. The loop detection function is accessible in the settings menu. When enabled, it would detect the loop and increment the 'x' value by 1 to break the loop. Please note that FuncBud is a MIDI app. The standalone version has an optional internal synth where you can enable or disable on the settings menu. The AUv3 plugin requires an audio app for output. For the AUv3 functionality, it needs to be hosted within an app such as AUM, Loopy Pro, Cubasis, Logic Pro, Nanostudio, Drambo, or apeMatrix.
