Sensor families and zones
Yamaha pad/module compatibility table (March 2025 PDF) distinguishes exact module inputs, zones and separate functions. An unverified table entry is not a tested failure. Different implementations can support multiple zones on similar connectors, so the preflight requires a declared zone ceiling and exact-pair evidence rather than deriving it from TRS.
Supported split configurations are narrow
Roland SPD-SX: two BT-1 setup and Roland TD-6/TD-6V paired-input example specify particular input/mode arrangements. Their settings do not transfer automatically to another module. The allocation planner assumes one equivalent pool, one group per dual-zone pad and at most two single-zone pads per explicitly eligible group. Extra cymbal resources must be reserved before counting.
Strike and controller functions differ
Audiofront eDRUMin 2.4.3 manual distinguishes trigger and controller paths and warns about specific powered-controller-input connections. This supports a separate foot-position route and an exact-manual safety boundary, not a general voltage, resistance or polarity rule. Faceplate labels alone cannot classify every manufacturer’s assignable function.
Assignments and symptoms need exact context
Roland TD-50 Quick Start describes how certain digital assignments affect corresponding analog trigger inputs. That is a model-specific shared-resource example, not a rule for all digital pads. Alesis DM10 troubleshooting separates supported connections, trigger behavior and settings. This site does not copy a generic calibration, reset or threshold prescription from those examples.
What each result can establish
- Preflight: whether the entered exact documentation covers requested functions.
- Allocation: a conditional count and logical worksheet, not physical jack mapping.
- Hi-hat route: required strike/position information paths, not measured controller response.
- Fault record: the next evidence layer, not a certified defective component.
