About

Binarhythmic Rhythm Generator

This app generates rhythmic MIDI outputs based on binary numbers, allowing for intricate control over note, velocity, and gate length. It offers advanced logic operations and randomization for unique rhythmic patterns. It functions as a standalone app and an AUv3 MIDI plugin.

Highlights
  • Binary-based MIDI sequencing
  • Configurable bit parameters (note, velocity, gate length)
  • Advanced logic operations (AND, OR, XOR)
  • Randomizer for note selection
  • Multiple gate types (Rest, Single, Multiple, Hold)
  • AUv3 MIDI plugin support
  • Standalone app functionality

Read full description

Binarhythmic is a MIDI sequencer that would generate rhythmic outputs based on the binary numbers. The sequencer has a counter, increasing on each sequencer cycle. The binary form of this number, something like "010110011".  Each 0 or 1 is a "Bit", and each bit is a MIDI output. If a bit is 1 then the gate is open for that bit, and if it's 0 then the gate is closed for that bit.  You can use the Multiplier parameter for controlling the sequencer counter.  The rate parameter controls the sequencer speed. Each bit has a note, velocity, gate length, trigger type and logic operation.  You can also vary the velocity and gate length. With the lower amounts of variety, you can humanise the sounds like Hi-Hats.  You can assign different MIDI channels to the bits and control different synths. The gate type is a very important parameter for the rhythm generation. On each sequencer cycle, if the gate is open for a bit; - Rest mode doesn't send the MIDI. - Single mode sends the MIDI once for the first sequencer cycle when the gate is opened. - Multiple mode sends the MIDI on each sequencer cycle while the gate is opened. - Hold mode sends the MIDI when the gate is opened and sustains it until the gate is closed Logic is one of the most powerful features of Binarhythmic. You can create endless rhythmic possibilities by using the logic operations. You can modulate the bits by applying logic operations on them with the other bits. - AND(&) operation opens the gate if the bit's gate is open AND the other bit's gate is open. - OR(+) operation opens the gate if the bit's gate is open OR the other bit's gate is open. - XOR(^) operation opens the gate if the other bit's gate is NOT open. With the randomizer you can randomize the notes on your bits in a range of notes that you can set. Or you can hand-pick the allowed notes from the list. With that feature, you can fully control the randomizer. In the "Random" mode, you can assign the randomization chance of the bits. When select the Random mode, the new Config button on the bottom toolbar appears and you can configure the randomizer. You can also access this configuration menu from the settings menu as well. In the multiple gate type mode, you can set the randomizer behaviour from the settings menu. If you toggle the "Randomize notes on each sequencer cycle" setting, then the randomizer will generate a new note on each sequencer cycle while the gate is open, if the gate type is multiple. Otherwise, it will randomize the note on the first sequencer cycle when the gate is opened and will trigger that note on each sequencer cycle until the gate is closed. Binarhythmic app runs as standalone app as well as AUv3 MIDI Plugin. You can create AU presets and use AU parameters of the AUv3 plugin. You can control or even automate every AU parameter of Binarhythmic.  You can modulate the multiplier parameter with PatternBud. You can also control the key and scale with BrainBud. Binarhythmic is a MIDI app and does not produce any sound on its own. You need to route its MIDI output to an audio app. For using the AUv3 plugin, you need an AUv3 host app such as AUM, Cubasis, Nanostudio, Loopy Pro etc.

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
