Tiny Time Machine

Olivia Artz Modular

An 8-tap stereo granular delay for Eurorack, mixing eight delay lines from milliseconds to minutes; supports clock sync, CV control over time, spread, and feedback, and can produce reverb-like, rhythmic glitch, or chaotic textures.1117

Capabilities 2

Delaydelay
Eight-tap stereo delay with times from milliseconds to several minutes, clock-syncable and CV-controllable.1117
Granular Synthesisgranular-synthesis
Granular delay engine distributes eight taps across time with controllable spread, producing granular textures, reverb-like spaces, and chaotic feedback.1117

Audio In Laudio-5V to 5V1117
Audio In Raudio-5V to 5V1117
Clockclock—Clock input that quantizes the delay lines to its tempo; the last tap (t) is always quantized to the clock when present.1117
Feedback CVcv-5V to 5V1117
Spread CVcv-5V to 5VCV input controlling delay spread distribution; negative voltage bunches taps toward now, positive bunches them toward the maximum delay time.1117
t/2vcv-5V to 5VExponential CV input for maximum delay time: +1V halves and -1V doubles the time set by the t knob; accepts -5V to +5V.1117

Parameters 3

NameTypeRangeBehavior
Feedbackknob—Within the arc-marked zone, audio neither decays nor swells; beyond that zone, feedback grows chaotically in a digital manner analogous to guitar-amp feedback.1117
Spreadknob—At noon all eight taps are evenly spaced; turning left bunches taps toward now (more recent delays); turning right bunches taps toward t (more distant delays), producing reverb-like textures.1117
Zones
Bunched toward now
Evenly spaced
Bunched toward t
  • Bunched toward now -100–0%Taps cluster near the present, providing more recent delays and fewer near the maximum time t.1117
  • Evenly spaced 0–0%All eight delay lines are evenly distributed across time, and all quantize to clock when present.1117
  • Bunched toward t 0–100%Taps cluster near the maximum delay time t, providing more distant delays and fewer near the present.1117
tknob0s – 8sSets the maximum delay time exponentially, giving finer control over shorter times; with CV input the range extends from 0.0001s to 150s.1117

Firmware history 3 versions

VersionReleasedNotes
1.1.1—Added support for the VCA Expander accessory.1117
1.0.1—Fixed a bug where all CV below 0V was recognized as 0V, which also prevented calibration data from being stored; users upgrading from v1.0 must re-run calibration.1117
1.0—Initial release; shipped with orders before March 25, 2024.1117
