Frequently Asked Questions - Horologic Solum Noise Engineering

What is the Horologic Solum?

The Horologic Solum is a 4HP voltage-controlled master clock generator for Eurorack modular synthesizers, featuring multi-mode clock division and an optional expander (Horologic Uter).

How do I select the clock source?

Use the INT/EXT switch. In INT mode, the internal clock runs with tempo control via knob and CV. In EXT mode, an external clock signal is expected at the input jack; the internal clock stops if no external signal is present.

What are the divisor modes?

The 204 switch selects three divisor modes: powers of 2 (2,4,8), odd numbers (3,5,7), and powers of 4 (4,16,64). These affect the four clock outputs.

How do I reset the clock?

Press the RST button or apply a gate to the RST input jack to reset the clock to the beginning of the measure. Holding the button pauses the clock.

Can I chain multiple Horologic Solum modules?

Yes, by using the EXT mode and connecting the clock output of one module to the input of another, you can sync multiple units.

What is the Horologic Uter expander?

The Horologic Uter is an optional expander that adds seven fixed-divisor clock outputs to your Horologic Solum, providing musically useful divisions.

What are the power requirements?

The module requires +12V at 50 mA and -12V at 5 mA on a standard 2x5 pin Eurorack power connector.

How do I use the CV input?

In INT mode, the input jack accepts CV (0-5V typical) to control the tempo. The TEMPO knob acts as an offset to the CV.

What is the depth of the module?

The Horologic Solum has a depth of 0.8 inches (about 2 cm), fitting most Eurorack cases.

How do I clean and maintain the module?

Disconnect power before cleaning. Use a soft, dry cloth to gently wipe the front panel and jacks. Avoid liquids and abrasive cleaners.

Overview

Type	Clock
Size	4HP Eurorack
Depth	.8 Inches
Power	2x5 Eurorack
+12 mA	50 mA
-12 mA	5 mA

Horologic Solum is a 4HP voltage-controlled clock generator. Three speed modes allow a wide range of rates. Horologic Solum also includes three divisor modes for offsetting up to four outputs. Use the internal clock or chain to an external clock to sync multiple HS.

Horologic Uter is an optional expander that offers an extra seven outputs at fixed, musically useful, divisors.

Interface

TEMPO

The Tempo knob allows for control of the speed of clock outs while the switch gives coarse control over three different speed modes. The Tempo switch adds in three different tempo speed ranges for coarse control.

INT/EXT

Choose the internal clock or chain multiple clocks together for added clock options. When in INT mode, the input jack acts as a CV control to the tempo, and the TEMPO knob acts as an offset. EXT mode expects an external clock, but this mode can also be used to stop the INT clock if no external clock is applied.

RST

Button and input jack: resets the clock to the beginning of the measure. The button also pauses the clock while it is held down.

204 (Divisor Mode)

Horologic Solum has three divisor modes. It can be set to divide by powers of 2 (2, 4, 8), odd numbers (3, 5, 7), or powers of 4 (4, 16, 64). Each yields different rhythmic patterns.

CLOCK OUTS

Horologic Solum offers four clock outputs. The numbers next to the jacks correspond to the divisor used in each different mode.

Horologic Uter (optional expander)

Horologic Uter offers seven fixed-divisor clock outputs.

Patch Tutorial

Horologic Solum and Horologic Uter are easy to use. Simply plug any output into any trigger input. Experiment with the Tempo dial and switch and Mode switch to get interesting, diverse, and useful patterns.
