PolyStep Sequencer For Reason

Propellerhead has introduced PolyStep Sequencer for Reason – described as “an evolved polyphonic step sequencer for your Reason Rack.”

Here’s what they have to say about it:

“Create sequences by drawing in notes, record in real time or record with step input and then let the magic begin. Transpose your sequences in real-time from MIDI input, always in scale. Grab single notes and drag them in the horizontal or vertical to create boxes. These boxes transform into chords, repeats, arpeggios or strumming. Create up to four variations of each pattern, switch between them manually, randomly or in sequence.

For the detail-minded, each note has separate properties. You can set basic values like pitch and velocity, but also go deeper with probability, timing offset, legato and more. And if you have dragged notes in your sequence to create boxes, the properties will allow you to set repeats, chord density, alternate voicings as well as settings for arpeggio or strum.

Sequence more instrument parameters with two separate CV tracks for every pattern and variation, like rhythmic control over your synth’s filter or an effect send.

PolyStep Sequencer can be a straight-up polyphonic pattern sequencer, a jam-friendly phrase sequencer, a song writer’s harmonic exploration tool or just about whatever you want it to be.


  • Polyphonic step sequencer with real-time, step time or graphical input
  • Scale-aware playback means no off-scale notes (unless you want it)
  • Jam and improvise dynamic arrangements with four evolving variation states
  • Explore chord progressions and chord structures by turning single notes into chords of varying complexity
  • Two CV tracks to control parameters on the instruments you are playing
  • Eight patterns, each with four variations
