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.

Ridgewalk is a standalone app and AUv3 plug-in. Ridgewalk lets you explore sound in unique ways not possible before. Meander between microscopic moments in a sample to create an infinite soundscape, or stretch or compress audio in realtime, all while recording and reacting to new input instantly. Ridgewalk is both a looper and a granular engine. Output is generated by a set of independent microloopers that traverse a single buffer of audio. The audio buffer can be freely recorded to, overdubbed over, and reverted to a previous version, and the microloopers will transition smoothly and instantly. With control over the microloopers’ size, behavior, and movement throughout the buffer over time, you’re free to reimagine and reinterpret audio like never before - all in realtime. Ridgewalk is designed as a modular tool for flexible usage. It is equally comfortable at the heart of your composition, collaborating with you as you perform, or as a finishing touch to provide a unique complementary atmosphere to deepen your mix. Ridgewalk is fully compatible with modulators such as Ableton CV or Bitwig LFOs to broaden horizons even further. Ridgewalk has the following controls available: Recording: Record via your choice of two unique techniques. Choose between automatic recording via input volume detection and a classic latching recording technique that can record infinitely. Buffers can be up to 60 seconds or 16 bars. Overdubbing: Freely overdub on top of existing audio with two methods. Choose between a traditional feedback dub or a unique sidechain dub which compresses existing audio against new input. Playback will smoothly transition to new recordings instantly. Layers: Each overdub creates a new layer, which you can then move between smoothly and revert to previous versions of audio. Full recall: All recorded audio will be saved and reloaded when reopening a project. Sample importing: Rather than record, Ridgewalk can import samples directly. Volume controls: Independent volume trim controls for dry and wet volume. Playback: Looper playback can be played and paused independently of input and recording. Playback will instantly reflect any changes to recorded audio. Hold time: Looper playback can be automatically paused after a defined time since starting. This allows Ridgewalk to act like a strange reverb or delay. Reverse: Playback can be reversed and audio can be recorded in reverse as well. Looper size: Loopers can span from microscopic fragments of the buffer to the full size, and can be synchronized with your BPM. Looper amount: Up to 7 microloopers are available, which move together in concert with one another. Drift: Looper size and positioning can be randomly and independently desynchronized to add variations and unpredictability. Blur: A one-stop-shop for increasing ambience: this controls looper crossfading as well as introduces reverb. Repitch: Playback can be repitched from ±2 octaves. Random movement (Wander): Looper positioning can be set to randomly wander the sample over time via Brownian motion. Sequential movement: Looper position can move linearly through a sample over a time defined in seconds or synchronized to your BPM. Manual looper positioning: Loopers can be positioned manually via tap or click, turning Ridgewalk into a performative instrument. Instant playback: Ridgewalk can start playing back from recorded audio as soon as it is able, turning its granular looping algorithm into a live effect. Transport syncing: Ridgewalk can be synced with your DAW’s transport to automatically start/stop playback or recording.
