LoopBud is a super simple yet very powerful MIDI recorder and looper. You can work with unlimited patterns. Although the 4-bar loops are very fun, you can work with an unlimited number of bars on each pattern! LoopBud has two record modes, Add mode and New mode. The "add mode" keeps adding new notes on each loop-cycle. The "new mode" clears out the previous recording and lets you record freshly on each cycle. You can work very fast with those modes. If you make a mistake, don't worry, you can use the "undo" option and get everything back! LoopBud has quantization enabled by default. You can toggle quantizing by pressing the "quantize" button on the top-left side. You can also set the level of quantization from the settings menu. If you want to speed up or slow down the clock, you can do so by pressing the "clock" button on the top-left side. You can achieve different effects on your live performances without a new recording. You can also focus on a single bar by pressing the bar measure on the top. You can either record or loop a single bar - which is a unique feature of LoopBud. In the settings menu, you can edit the piano roll's lowest and highest notes. The notes on the piano roll is not editable. However, you can export MIDI from the settings menu, and do editing on your favorite piano roll editor app! LoopBud is not an audio app, it's a MIDI app. You need to connect a MIDI input and a MIDI output for LoopBud to work. You can do so from the settings menu in the standalone app. You can use the MIDI matrix editor on your DAW if you are using the AUv3 plugin. LoopBud also supports Ableton Link on the standalone app.

Introducing ChaosArp, the next-level MIDI arpeggiator/step sequencer designed to transform your musical ideas into intricate, dynamic patterns with a unique twist. ChaosArp is not just any arpeggiator; it's a powerhouse tool that uses the same advanced algorithms as LoAdKer to modulate pitch, rhythm, velocity, and duration, creating evolving, complex but high musical patterns that breathe life into your music. Dive into the heart of your creativity with ChaosArp's innovative ‘rhythm event’ feature, which allows you to explore a variety of rhythmic modifications. From repeaters to stretchers and rests for extra space and emphasis—ChaosArp has it all. Each one of these rhythm events can be assigned to any of the 6 available slots, offering limitless possibilities. Fine-tune your sonic exploration with the innovative ‘variance’ control - which goes one step beyond the simple ‘probability’ control that most arpeggiators have. Adjusting this setting for either pitch or rhythm (or both) will vary the character of the generated sequences, from fairly minimalistic to completely chaotic, thus opening up a world of endless variations. Elevate your music production today with ChaosArp and unleash patterns that inspire! Features: - Two modes: arpeggiator and stepper - 1-16 steps - Scale quantizer, never miss a note again! - Variable rate, from 1/128 to 4 beats - 3 arpeggiator modes (up, down, up/down) - 3 stepper modes (forward, backward, ping-pong) - 1 to 4 octaves range - Latch mode - Pitch randomizer with probability and variance control and random octave - Rhythm event selector with probability and variance control - 6 assignable rhythm event slots - 13 rhythm event algorithms, including repeaters, stretchers, and rests - Repeat, stretch, and repeat rest probability controls for further customization of the rhythm event algorithms - Randomizable velocity and duration with variable range - 4 performance buttons that temporarily override the probabilities of pitch, rhythm, velocity, and duration - Automatable parameters
