T's Musical Tools
A collection of esoteric VCV Rack modules for manipulating seeded RNG and polyphonic signals in interesting ways.
Design Philosophy
TMT is a toolkit focused on control voltage manipulation rather than audio generation. The modules feature no knobs, only jacks—all control happens via CV inputs. This design encourages a pure modular patching approach where everything is dynamic and automatable.
While primarily designed for routing signals and working with control voltages, most modules can operate at audio rate for experimental sound design.
The Modules
Spellbook
Tracker-style plaintext sequencer using RhythML notation. Bring the power of text-based composition to your modular patches.
Page
Expander module for Spellbook that extends column capacity for more complex sequences.
Shuffle
Randomly reorder polyphonic signal channels with seedable, deterministic randomization.
Sort
Rearrange and filter polyphonic cables using spreadsheet-like functions and CV control.
Seed
Generate 16 reproducible random voltages from a seed input. Perfect for creating controlled chaos.
Ouroboros
Step sequentially through polyphonic input channels, turning any poly cable into a sequence.
Append
Combine up to 16 input signals into a selectable polyphonic output with CV-controlled subsetting.
Stats
Calculate statistical measures (mean, median, mode, variance, etc.) of polyphonic signals.
Calendar
Generate time and date-based LFO-like control voltages synced to your system clock.
Sight
Oscilloscope with logarithmic, non-linear time scaling for multi-scale signal visualization.
Spine
Provides frequently-used constant CV offsets, inverse, and reverse operations.
Blankt
Resizable blank panel to organize your rack aesthetically.
Key Features
