Frequently Asked Questions - TM 2hp

What does TM stand for in the 2hp TM module?

TM stands for Turing Machine, a random voltage generator and sequencer popular in eurorack systems.

How do I power the 2hp TM module?

Connect a standard 10-pin eurorack ribbon cable to your case's bus board. Ensure the red stripe aligns with -12V as marked on the module.

What is the function of the Length knob?

The Length knob controls the length of the generated sequence, from 1 to 16 steps.

How does the Bias knob affect the output?

Bias adds a constant voltage to the CV output, shifting the overall pitch or parameter range.

What does the Write button do?

Pressing Write locks the current sequence, preventing it from mutating until unlocked.

Can I use the TM module without a clock input?

No, the TM requires a clock signal on the Gate In to advance the sequence. No internal clock is provided.

What is the output voltage range?

CV Out ranges from 0V to 5V (or -5V to 5V depending on bias). Gate Out is 0V to 5V trigger.

Is the 2hp TM compatible with all eurorack cases?

Yes, as long as the case provides +12V and -12V power. Its 2HP width fits any standard rails.

How do I clean the module?

Use a soft, dry cloth. Avoid moisture, solvents, or compressed air near the panel.

What if my module is not working?

Check power polarity and cable connection. Ensure your case supplies sufficient current. If issues persist, contact 2hp support.

USER MANUAL TM 2hp

TM is a probabilistic random sequence generator based on the research of Alan Turing. His Turing machine was a mathematical model of computation that could, in theory, create any output based on a set of instructions and input variables. In a similar way, the TM chooses random values for steps in a sequence based on the user's probability settings. By manipulating probability and sequence length, the module can generate an infinite number of sequences. Whether you're looking for a controlled random source, or an evolving melody generator, TM has you covered.

• Probability control from full random, to locked sequence
  • Sequence length from 1-32 steps
  • Amplitude control for limiting the range of new random values
• Run through a quantizer for generative melodies

Installation

To install, locate 2 HP of space in your Eurorack case and confirm the positive 12 volts and negative 12 volts sides of the power distribution lines. Plug the connector into the power distribution board of your case, keeping in mind that the red band corresponds to negative 12 volts. In most systems, the negative 12 volt supply line is at the bottom. The power cable should be connected to the TM with the red band facing the front of the module.

Specifications

Format: 2 HP Eurorack module

Depth: 47mm (Skiff Friendly)

1. TRIG LED:

LED that indicates when a change in sequence has been made

2. TRIG:

Trigger input

A random voltage will emit from OUT when a trigger or gate signal is received by the TRIG input

Threshold: 2.5V

3. PROB CV:

Control voltage input for PROB

Range: 0V - 5V

4. PROB:

Controls the probability of the random voltages assigned to each step in the sequence

If the knob is far left, probability will be set to 100% and a new random voltage will be generated for the active step of the sequence when a trigger or gate signal is present at the TRIG input

If the knob is far right, probability will be set to 0% and the sequence will be locked to its last random voltage value, advancing to the next successive step in the sequence without any change in voltage

5. STEPS CV:

Control voltage input for STEPS

Range: 0V - 5V

6. STEPS:

Controls the length of the sequence

If the knob is far left, 2 steps will be included in the sequence If the knob is far right, 32 steps will be included in the sequence

7. AMP:

Amplitude control for the random voltage emitted from OUT

If the knob is far left, random voltage will be fully attenuated (0V)

If the knob is far right, random voltage will be full scale (5V)

8. OUT:

Random voltage output

Range: 0V – 5V
