TM 2HP Cheat Sheet
TM is a probabilistic random sequence generator for Eurorack inspired by Turing Machine concepts. It is ideal for generative and evolving sequences or controlled random voltage sources.

Quick Operation
- Power: 2HP, 47mm depth (Skiff friendly), +12V: 23mA, -12V: 7mA
- Install: Ensure red stripe = -12V (down in most cases).
- Trigger: Send trigger/gate ≥2.5V to TRIG; step advances and decides to create new random voltage based on PROB.
- PROB (Probability):
- Left (100%): Always generate new random voltage per step.
- Right (0%): Sequence "locks" to current voltages, advances steps without further randomness.
- CV: Patch in modulation (e.g., LFO, envelope) to vary randomness dynamically.
- STEPS (Sequence Length):
- Sets how many steps before looping (1–32). CV controllable.
- AMP (Amplitude):
- Sets range of output voltage. Full right = up to 5V, full left = 0V.
- OUT: Output stepped random CV to pitch quantizer, filter cutoff, etc.
Patch Tips
- For evolving melodies, patch OUT to a quantizer then to an oscillator pitch input.
- Use an LFO or random CV into PROB CV for dynamic randomness control.
- Adjust STEPS to taste for short or extended looping patterns.
