4. Key Product Lineup

MeldaProduction develops over 100 plugins in total – effects, instruments, and analysis tools – and is based in Prague, Czech Republic. Every product uses a “Free for life updates” model, so once you buy, you keep getting new versions, new features, new Turbo-series models, and new MSoundFactory instruments at no extra cost.

Sales center on bundles: the effects-only MTotalFXBundle and the MCompleteBundle (which also includes instruments) are the flagships. MCompleteBundle even supports a monthly Subscribe-to-Own plan (once your cumulative monthly payments reach the full price, it automatically converts to a perpetual license). On top of that, the “Eternal Madness Discount” (a permanent weekly discount that puts 4 plugins at half price every week) and the free “MFreeFXBundle (37 plugins)” are also Melda trademarks.

Here we organize MeldaProduction’s main bundles and most popular individual plugins by category.

Bundle Lineup

MeldaProduction’s products are grouped into several bundles by purpose. Rather than buying individual plugins one by one, the standard approach is to start from the bundle that fits your goals.

Note: MCompleteBundle is the only bundle that supports the monthly Subscribe-to-Own option. Once your cumulative monthly payments reach the full price, it automatically switches to a perpetual license.

MTurbo Series (Vintage Modeling)

The MTurbo series packs a large number of legendary classic units into a single plugin, letting you switch between them with one click. Because the user interface is nearly identical across every model, once you learn one workflow you can operate every model intuitively.

MTurboReverb (100 reverbs)

MTurboReverb is a groundbreaking algorithmic reverb with roughly 100 reverbs in a single plugin, and you can even design your own reverb algorithms. It covers rooms, halls, plates, shimmer-style reverbs, and even 2D positioning reverb. Its programmable engine lets you assemble your own algorithm to build a completely original reverb.

MTurboDelay (41 delays)

MTurboDelay is the ultimate delay, combining 41 delay plugins into one. It features 41 different delay designs inspired by both analog and digital sources. From basic echoes to multi-tap, filtering, pitch shifting, and advanced feedback processing including distortion, you can switch with a single click. Because the workflow is unified, getting comfortable with each delay takes only minutes.

MTurboEQ (12 vintage EQs)

MTurboEQ is a unique vintage EQ that brings together 12 classic vintage-style equalizers in one plugin. You can access multiple classic EQs with one click, dramatically speeding up your workflow. Since every model shares nearly the same user interface and functionality, you never have to relearn the controls for each unit.

MTurboComp (14 vintage compressors)

MTurboComp is the ultimate compressor, emulating 14 classic vintage-style analog compressors. You can also design your own super compressor, with sidechain, HP/LP filters, Saturation, Dry/Wet, and more all operated through a unified interface.

MTurboAmp (30+ guitar amps & distortion pedals)

MTurboAmp is a guitar amp simulator featuring around 30 amp heads and over 10 distortion pedals. You can access the inner workings of the amp models to customize them to your liking, or even design an original amp from scratch. It is built to be used together with the dedicated cabinet simulator “MCabinet”.

Phase Correction & Time Alignment

MAutoAlign

A plugin that automatically solves the phase-cancellation problem that inevitably occurs when recording with multiple microphones. MAutoAlign automatically detects the ideal delay amount and polarity inversion – just place an instance on each track you want to fix and click a button. No complex routing or sidechain required. From version 11.02 onward it also supports per-frequency phase rotation correction, handling phase shifts in 3D space and even phase changes after EQ.

MTrackAlign

MTrackAlign is a high-performance alignment plugin that instantly time-aligns multiple audio tracks on ARA-compatible DAWs. Using a guide track as the reference, it automatically analyzes and syncs multiple recordings, greatly reducing manual editing.

By leveraging ARA (Audio Random Access) technology, it instantly analyzes entire audio clips without playback and applies precise timing correction with one click.

It also handles film and post-production tasks such as ADR (Automated Dialogue Replacement) syncing and aligning Foley and sound effects. Supported DAWs: Cubase / Nuendo / Studio One / Logic Pro X / Reaper / Samplitude / Pro Tools (beta). FL Studio, Ableton Live, and Bitwig are not supported because they lack ARA.

Microphone Simulator

MMicSim

MMicSim is a microphone simulator that instantly transforms the sound of your existing microphone into that of a high-end studio mic. Just choose the mic you are using under “Your Mic” and specify the target mic under “Desired Mic”, and your recorded sound instantly takes on a different microphone character.

All microphone data is precisely analyzed in a professional anechoic chamber. Using the multi-dynamic sweep technology that underpins MMatcher, it accurately captures both frequency response and dynamic behavior, achieving a natural simulation free from the influence of room ambience and reflections.

It also boasts a rich library of over 100 microphones, covering everything from standard studio mics to rare vintage models such as the Telefunken ELA M251 and Neumann M49b. The database is continually expanding.

It is effective not only for vocals but also for instruments such as drums and guitar amps. The Smoothness control adjusts spectral roughness, and the Dry/Wet knob controls how strongly the algorithm itself is applied.

Creative Effects

MRhythmizer

MRhythmizer is a Time / Volume / Filter sequencing arrangement effect from MeldaProduction. Three independent sequencers control Time, Volume, and Filter respectively, letting you arrange effects like gate, glitch, repeat, and scratch in fine, complex detail while switching freely between editable sequencer presets via MIDI. There is also a 6-band multiband version, MRhythmizerMB.

Instruments (Sound Sources)

MSoundFactory Series

MSoundFactory is a modular-design virtual instrument that lets you freely combine modules such as oscillators, filters, samplers, and effects. With full MPE support, cutting-edge oscillator technology, and a modular effects engine, it covers virtually every synthesis method – subtractive, FM, granular, physical modeling, wavetable, and sampling.

When you buy MSoundFactory, every instrument MeldaProduction releases in the future, plus all drum libraries for MDrummer, become available at no additional cost. This is a major perk of the MSoundFactory series.

MDrummer

MDrummer is Melda’s flagship drum instrument, serving as both a drum machine and a virtual drummer. It has a huge library packed with samples, multisamples, rhythm patterns, drum kits, and loops, covering every genre and rhythm style – rock, pop, drum & bass, R&B, salsa, jungle, jazz, progressive metal, and more.

Its standout feature is the rhythm generator: give it a simple bass loop and it automatically generates a complete drum track including fills, intros, and outros to match. You can choose between several production styles such as the MIDI Command Method, the built-in sequencer, and Jam mode. MSoundFactory users can also download additional drum libraries (addons) for free.

MGuitarArchitect

MGuitarArchitect is an all-in-one guitar chain simulator built on MTurboAmp and MCabinet. It includes 40 amps, 13 cabinets, 26 stomp boxes, 10 studio effects, and 8 utilities, and with three customizable chains (16 slots each) plus one sidechain chain, you can freely build up to 64 effects in series or parallel.

It also features advanced functions such as POLYTUNER (polyphonic tuner), Doubler, automatic input-level analysis, Neural Amp Modeler (NAM) support, and IR loading. A unique strength is that if you own other Melda plugins like MTurboEQ, MTurboComp, MTurboDelay, MTurboReverb, or MDynamicEQ, you can insert them anywhere in the guitar chain.
