# Delay Effects — Parameter Guide > Source: DeepMind 12 Owner's Manual, pp. 98–99, 111–114 (§9.2–9.3) > Parent: [effects.md](../effects.md) ## Overview Six delay effects ranging from pristine stereo delay to lo-fi decimation. Most support time-sync options (rhythmic fractions of the master tempo). Parameters marked `*` are available as mod matrix destinations. --- ## Delay (Stereo Delay) — type 13 Full-featured stereo delay with independent L/R channels, feedback modes, and filter controls. 12 parameters. | # | Abbr | Parameter | Units | Min | Max | Mod* | Description | |--:|------|-----------|-------|-------|--------|:----:|-------------| | 1 | MIX | Mix | % | 0 | 100 | * | Wet/dry balance | | 2 | TIM | Time | ms | 1.0 | 1500 | | Master delay time (time-sync: 4 to 1/64 bars) | | 3 | MOD | Mode | — | — | — | | ST (stereo), X (cross-feedback), M (mono mix), P-P (ping-pong; disables FeedR) | | 4 | FCL | FactorL | — | — | — | | Left delay as fraction of master: 1/4, 3/8, 1/2, 2/3, 1, 4/3, 3/2, 2, 3 | | 5 | FCR | FactorR | — | — | — | | Right delay as fraction of master | | 6 | OFS | Offset | ms | -100 | 100 | | Delay difference between L and R | | 7 | LC | LoCut | Hz | 10 | 500 | * | Low-frequency exclusion | | 8 | HC | HiCut | Hz | 200 | 20000 | * | High-frequency exclusion | | 9 | FLC | FeedLC | Hz | 10 | 500 | * | Low-cut filter in feedback path | | 10| FBL | FeedL | % | 0 | 100 | * | Left channel feedback amount | | 11| FBR | FeedR | % | 0 | 100 | * | Right channel feedback (disabled in P-P mode) | | 12| FHC | FeedHC | Hz | 200 | 20000 | * | High-cut filter in feedback path | ### Feedback modes (param 3) | Value | Mode | Behavior | |-------|------|----------| | ST | Stereo | Normal feedback for both channels | | X | Cross | Feedback crosses between L and R | | M | Mono | Mono mix within feedback chain | | P-P | Ping-Pong | Bounces between channels (FeedR disabled) | --- ## 3TapDelay (3-Tap Delay) — type 14 Three delay stages with independent timing, gain, and pan per stage. 12 parameters. | # | Abbr | Parameter | Units | Min | Max | Mod* | Description | |--:|------|-----------|-------|------|--------|:----:|-------------| | 1 | TIM | Time | ms | 1.0 | 1500 | | Master delay time (= stage 1 time).
