TG100 Reverb is an algorithmic reverb plugin extracted from Martinic’s ACE-modeled Yamaha TG100 sound module, bringing the 1991 hardware’s LDSP chip reverb section — including its dedicated delay memory, early reflections, pre-delay, and high-frequency damping behavior — into a standalone effect usable on any source. It provides eight algorithm types across Hall, Room, Plate, and Delay categories, with four controls covering send, decay, output level, and dry/wet mix. Its differentiator is source isolation: the TG100’s internal reverb was previously locked to its own internal sounds, and this plugin makes that specific chip’s character available to any input without routing audio through the hardware module. For any producer searching specifically for early 1990s compact digital reverb character rather than a modern algorithmic reverb emulating that era, this is that character extracted from its original hardware source.

Key Takeaway

Activates when a session needs the specific compact, slightly metallic digital character of early 1990s GM module reverb — the space that sits behind retro productions, lofi electronic work, video game music, and pop productions from that era — rather than a modern reverb designed to sound smooth and spatially accurate. Displaces generic “vintage reverb” presets in broader reverb plugins when the TG100’s specific LDSP chip character, not an approximation of it, is the goal. Accepts only mono input — a signal-path constraint that means stereo sources require a mono summing stage or a parallel instance approach before the reverb processes the signal.

Eight Algorithm Types and What the LDSP Chip Shapes Them With

The eight types — Hall 1, Hall 2, Room 1, Room 2, Plate 1, Plate 2, Delay 1, Delay 2 — all run through the same LDSP chip architecture, meaning each type carries the chip’s own coloration characteristics on top of its specific spatial algorithm. The dedicated delay memory connected directly to the LDSP chip is what shaped the original hardware’s specific character: the memory’s timing and capacity constraints determined how early reflections arrived, how the pre-delay behaved, and how high-frequency content was damped across the tail. These are hardware constraints replicated in the model rather than parameters a user adjusts — they’re part of what makes the reverb sound like a 1991 GM module rather than a modern design optimized around the same algorithm types.

The result across all eight types is a reverb that sits compactly rather than spreading wide, and that has a slightly digital edge rather than the smooth diffusion of a modern high-quality algorithmic reverb. Hall 1 and Hall 2 produce small-to-mid-sized spaces with that specific early-digital coloration; Room types are similarly compact; Plate types have the characteristic metallic shimmer of early digital plate emulation rather than the warmer, denser plates a modern reverb would produce. The Delay types add repeat-based echo with the LDSP chip’s same frequency response limiting applied across the repeats.

Four Controls and the Two-Screen Layout

The main FX screen exposes four controls — Send, Decay, Output Level, Dry/Wet — plus the reverb type selector, keeping the interface close to how the original TG100 hardware section operated. The Settings screen exposes the same controls in a more direct layout alongside additional parameters not visible on the hardware-faithful main screen. This two-screen structure is Martinic’s standard approach across their product line: one screen for the original hardware experience, a second for practical plugin use.

The Send control determines how much signal enters the reverb algorithm — at lower values it functions as a parallel blend before the Dry/Wet control shapes the final mix, so the interaction between Send and Dry/Wet gives more nuanced control over how much reverb character appears in the output than either control alone. Decay sets the reverb tail length within the constraints each algorithm type imposes — the range available on Hall types differs from the range available on Delay types, since the LDSP chip’s memory allocation per algorithm type affects how long a tail each type can sustain. The developer responded directly to a KVR suggestion about simplifying the control layout to a single rotary encoder, explaining the two-screen approach as the deliberate solution — a hardware-accurate front screen and a more ergonomic Settings screen rather than a condensed single-control layout.

Mono Input and Bus Workflow

TG100 Reverb accepts only mono input and outputs a stereo signal — the LDSP chip in the original hardware operated this way, and the model preserves that path rather than adding a stereo input stage the hardware never had. For stereo sources on a track insert, this requires either summing the stereo input to mono before the plugin or sending a mono signal. The bus and send workflow — routing a mono or summed signal to a dedicated reverb bus loaded with TG100 Reverb — is a cleaner fit for the plugin’s signal path than track insert use on stereo sources, and matches how the developer describes the intended use in the product documentation.

The 16 presets cover the eight original TG100 hardware reverb presets plus eight new ones designed specifically for the standalone plugin context. Loading one of the eight original hardware presets reproduces the same settings that appeared on the TG100’s factory preset list, giving a direct reference for how the reverb type and parameter combination sounded in its original hardware application. The eight new presets extend the same eight algorithms into settings optimized for DAW use rather than General MIDI playback, covering vocal, drum, guitar, and synth applications.

One Chip’s Reverb, Freed From the Module That Contained It

TG100 Reverb delivers the LDSP chip character that the original Yamaha hardware reserved for its own internal sounds — now available on any source, with the same mono input path the chip always required.
