TheReelPeet-Seq

TheReelPeet-Seq is a dual, clock-driven generative sequencer for VCV Rack, designed for evolving, overlapping melodic motion rather than strict step programming.

Each lane produces randomized CV values over a configurable number of steps, with independent tempo control, gating, and the ability to temporarily freeze motion using a HOLD input. The module is intended to be exploratory and musical, rewarding asymmetry and interaction between lanes.

TheReelPeet is licensed under the MIT license.

Overview

TheReelPeet-Seq contains two independent sequencer lanes (A and B).

Each lane includes:

• Variable step length
• Randomized CV values per step
• Per-lane BPM control (knob + CV input)
• HOLD CV input to temporarily freeze the sequence
• RUN control (gate-based)
• Randomize trigger input
• 1V/Oct output
• Gate output

The lanes are intentionally symmetrical but independent, making it easy to create phase-shifting or polyrhythmic melodic structures by using different step counts, BPM values, and modulation sources.

Controls & I/O (per lane)

BPM

• Knob: Sets the base tempo for the lane.
• CV Input: Overrides the knob when patched and updates the knob position to match.

Length

• Sets the number of steps in the sequence.

Run

• Button: Toggles run state when no RUN CV is patched.
• RUN CV Input: Gate-based control.
  • High voltage = running
  • Low voltage = stopped
  • When patched, this input overrides the toggle button.

Random

• Button: Randomizes the sequence values.
• Random CV Input: Trigger-based. Any rising edge will re-randomize the lane.

Hold

• HOLD CV Input: Temporarily freezes the current step.
• While HOLD is active, the sequence does not advance but continues to output the current CV value.
• When HOLD releases, the sequence resumes normally.

Outputs

• 1V/Oct CV Output: Current step value.
• Gate Output: Emits a short gate when a step advances.

Intended Use

TheReelPeet is best used as a generative modulation and melody source, rather than a traditional step sequencer.

Some recommended approaches:

• Use different step lengths and BPM values per lane to create evolving, non-repeating patterns.
• Drive the CV outputs into an external quantizer for harmonic control.
• Use slow or probabilistic sources (e.g. random gates, envelopes, sample & hold) to:
  • Trigger randomization
  • Gate RUN on and off
  • Apply HOLD at musically interesting moments
• Let one lane run continuously while the other is periodically stopped or frozen to introduce phrasing.

The module is intentionally flexible and open-ended; experimentation is encouraged.
