# Effects — Parameter Guide

## What this controls

The DeepMind 12 has a built-in digital effects engine with **4 independent FX slots** (`fx1`–`fx4`). Each slot can be loaded with any of 35 effects. The FX engine sits after the analog VCA in the signal chain.

## Architecture

- **4 FX slots** — each independently selectable from the 35 available effects
- **Routing modes** — 10 routing configurations (M-1 through M-10) control how FX slots connect: serial, parallel, or hybrid
- **12 parameters per slot** — every effect exposes up to 12 parameters via `fxN.param.1` through `fxN.param.12`
- **Output gain** — each slot has an independent output gain (`fxN.outputGain`, NRPN 218–221)
- **FX mode** — global insert/send/bypass setting (`fx.mode`, NRPN 222)
- **Mod matrix destinations** — many FX parameters are available as mod matrix destinations (marked with `*` in the detail files)

## NRPNs

| FX mode           | 222         | 0–255  | Insert/Send/Bypass                       |

## Important: internal type values ≠ manual order

The manual lists effects 1–35, but the synth's internal `fxN.type` values use a different numbering. **Always use the internal type value** when setting `fxN.type` via NRPN.

## How to set an effect

1. Choose the FX slot (1–4) and set its type. `fx1.type` **accepts both `rawValue:` and `label:`**:
   ```
   fx1.type  label:"T-RayDelay"    # or rawValue: 21
   ```
2. Set parameters using either the **typed names** (preferred — self-documenting) or the positional names:
   ```
   fx1.tRayDelay.mix  value: 0.15    # same as fx1.param.1 value: 0.15
   fx1.chorus.mix     value: 0.70    # same as fx2.param.6 value: 0.70
   ```
   Typed names (`fxN.<effectName>.<key>`) are full `set_param` targets — not read-only. The `condition` on them is snapshot-display-only and has no effect on writes. Read the detail file to find the key names and their param index order.
3. The positional names `fxN.param.1`–`fxN.param.12` are always valid as a fallback when you know the index from the detail file.

## Common patterns

- **Reverb on everything**: Put a HallRev (type 1) or AmbVerb (type 4) in one slot. Set Mix to taste (param mapping in [reverbs.md](effects/reverbs.md))
- **Chorus + reverb in one slot**: Use ChorusVerb (type 24) to save FX slots
- **Tempo-synced delay**: Many delay/modulation effects support time-sync options; the Factor/Time parameters list rhythmic fractions
- **Mod matrix → FX**: Parameters marked `*` in the detail files can be targeted as mod matrix destinations
