Stochas is a probabilistic polyrhythmic step sequencer / chord generator.

Stochas is at it’s core a step sequencer, which means it generates MIDI notes. As such it does not generate any sound of it’s own but can be used to sequence other plugins and/or hardware synthesizers. Although it can be used for basic step sequencing, it’s main function is to provide randomness to the step sequencing process. It does this in a few ways:
  • Randomly determine whether a note should be played or not (create more dynamic and varied drum patterns).
  • Randomly choose between two or more notes to play at a specific time (create random or semi-random melodic or drum lines).
  • Add slight timing randomness to notes so that they play slightly before or after their position.
  • Add randomness to velocity and length of notes.
In addition to the randomness features, it offers a wealth of features:
  • Suitable for both drum and melodic programming.
  • Live performance features - Most features can be controlled by MIDI so that you can mute/unmute layers, switch patterns, change timing, transpose notes, etc.
  • Polyrhythms - Create up to 4 simultaneous layers with different time signature, playback speed and/or number of steps per layer.
  • Patterns - switch between patterns during playback for more variety.
  • Timing - Parts can be played at eg half-time or double-time, etc
  • Groove and humanization - Steps can be individually shifted off the grid. Basic swing can be applied, as well as grooves. Grooves can be imported from MIDI files.
  • Chords - quickly select and add chords to your sequence.
  • Note customization - Select which MIDI notes are visible in your grid, and even customize the names (useful for drumkits). These customizations can be imported/exported. In addition you can select from standard scales to make it easy to program in melodies.
  • Chain mode allows procedural programming (e.g. “if this note plays/doesn’t play then always/never play this other note”).
  • Record incoming MIDI to the grid.
  • Themable interface.

This thing is GREAT..... it can do complex stuff, thanks to the developper, and THIS VST3 works fine in VSTHOST..... it's one of my favorite sequencer so far... I think I have all the free sequencers on the market, but this one is the easiest to use, and low CPU usage... it's a win

Stochastic sequencing throws up things you don't expect. These types of sequencers are often best used on the less important instruments in a mix, and can be a bit too unpredictable for use on the main rhythm. This is a great plugin, my DAW (Ableton), doesn't have stochastic sequencing, so this is useful for me. Thank you developer.
