3. Key Product Lineup
MeldaProduction is a software company based in Prague, Czech Republic, offering more than 100 plugins spanning effects, instruments and analysis tools. Every product adopts “Free for life updates”: once you buy it, new versions, new features, newly added Turbo models and new MSoundFactory instruments keep coming with no extra charge — a major feature.
Sales center on bundles, with the effects-only MTotalFXBundle and the instrument-inclusive MCompleteBundle as the flagships. MCompleteBundle also supports a monthly Subscribe-to-Own (it automatically converts to a perpetual license once your cumulative monthly payments reach the full price). On top of that, the “Eternal Madness Discount” (a permanent weekly discount where 4 plugins are 50% off each week) and the free plugin bundle “MFreeFXBundle (37 plugins)” are also hallmarks of Melda.
Here we organize MeldaProduction’s main bundles and its most popular individual plugins by category.
Bundle Lineup
MeldaProduction products are grouped into several bundles by purpose. Rather than buying individual plugins one at a time, the standard approach is to start from the bundle that fits your goal.
| Bundle | Contents | Count | Use |
|---|---|---|---|
| MFreeFXBundle | A collection of free plugins | 37 | A basic set of free-to-use effects |
| MEssentialsFXBundle | A curated selection of essential production effects | 10 | Entry-level, low price |
| MMixingFXBundle | Mixing effects | 36 | For mixing engineers |
| MMasteringFXBundle | Mastering effects | 24 | For mastering |
| MCreativeFXBundle | Creative effects | 38 | Sound design / experimental processing |
| MTurboBundle | The 5 MTurbo products (Amp/Comp/Delay/EQ/Reverb) | 5 (equivalent to 160+ devices) | Vintage-style sound shaping overall |
| MTotalFXBundle | All of Melda’s effect plugins | 108 | Every effect included |
| MCompleteBundle | All effects + all instruments | 112+ | All effects and instruments |
Point: MCompleteBundle is the only one that supports monthly Subscribe-to-Own. Once your monthly payments reach the full price cumulatively, it automatically switches to a perpetual license.
The MTurbo Series (Vintage Modeling)
The MTurbo series consolidates many historic units into a single plugin so you can switch between them with one click. Because the user interface is nearly identical across all models, once you learn one workflow you can intuitively operate them all.
MTurboReverb (100 reverbs)
MTurboReverb is a groundbreaking algorithmic reverb with about 100 reverbs in a single plugin, and you can even design your own reverb algorithms. It covers rooms, halls, plates, shimmer types and 2D positioning reverbs. With a programmable engine, you can build your own algorithms and create completely original reverbs.
| Feature | MTurboReverb | MTurboReverbLE |
|---|---|---|
| Included reverb algorithms | About 100 + user-customizable | About 100 (presets only) |
| Editing | Can design original algorithms | No editing |
| Multiband support | Multiband version MTurboReverbMB available | Not supported |
| Target user | For professional production | For light users |
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, switchable with one click — from basic echoes to advanced feedback processing with multiple taps, filtering, pitch shifting and distortion. Because the workflow is unified, it only takes a few minutes to get comfortable with each delay.
MTurboEQ (12 vintage EQs)
MTurboEQ is a unique vintage EQ combining 12 classic vintage-style equalizers into one plugin. You can access multiple classic EQs with one click, greatly speeding up your workflow. Since every model shares nearly the same interface and features, there is no need 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 and dry/wet all controlled from a unified interface.
| Feature | MTurboComp | MTurboCompLE |
|---|---|---|
| Included compressors | 14 + user-customizable | 14 (presets only) |
| Editing | Can design original compressors | No editing |
| Multiband support | Multiband version MTurboCompMB available | Not supported |
| Target user | For professional production | For light users |
MTurboAmp (30+ guitar amps and distortion pedals)
MTurboAmp is a guitar amp simulator with about 30 amp heads and over 10 distortion pedals. You can access the internals of the amp models to customize them to your taste, or design original amps from scratch. It is designed to be used together with the dedicated cabinet simulator “MCabinet”.
Phase Correction & Time Alignment
MAutoAlign
A plugin that automatically resolves the phase cancellation 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 is needed. Since version 11.02 it also supports per-frequency phase rotation correction, handling phase shifts in 3D space and phase changes after EQ.
MTrackAlign
MTrackAlign is a high-performance alignment plugin that instantly time-aligns multiple audio tracks in 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 the entire audio clip without playback and performs accurate timing correction with one click. Because it can precisely align even the consonants and breaths of layered vocals, choruses and harmonies come together cohesively. It is also effective for double-tracked guitars and bass and for correcting the rhythm section.
It also handles video and post-production uses such as ADR (automatic 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.
Mic Simulator
MMicSim
MMicSim is a mic simulator that instantly transforms your mic into the sound quality 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 the recorded sound instantly takes on a different mic character.
All mic data is precisely analyzed in a professional anechoic chamber. Using the multi-dynamic sweep that underpins MMatcher, it accurately captures frequency response and dynamic reaction, achieving a natural simulation free from room and reflection coloration.
It also features a rich library of over 100 mics, 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 and Filter sequence-arrange effect from MeldaProduction. Three independent sequencers control Time, Volume and Filter respectively, letting you arrange gate, glitch, repeat and scratch effects in fine, complex detail while switching freely-editable sequencer presets from MIDI. MRhythmizer also has a 6-band multiband version, MRhythmizerMB.
Instruments
MSoundFactory Series
MSoundFactory is a modular-design virtual instrument where you can freely combine modules such as oscillators, filters, samplers and effects. With full MPE support, the latest oscillator technology and a modular effect engine, it covers nearly every synthesis method: subtractive, FM, granular, physical modeling, wavetable and sampling.
When you buy MSoundFactory, all future instruments MeldaProduction releases, plus all drum libraries for MDrummer, become available with no extra charge. This is a major perk of the MSoundFactory series.
| Feature | MSoundFactory | MSoundFactoryLE | MSoundFactoryPlayer |
|---|---|---|---|
| Price | Paid (full) | Paid (budget) | Free |
| Included sounds | All | All | Limited (a few patches) |
| Editing (Edit Screen) | Yes, full access | No | No |
| Third-party instruments | Yes | Yes | Yes |
| Free new instruments | Yes | Yes | – |
MDrummer
MDrummer is Melda’s flagship drum instrument that is both a drum machine and a virtual drummer. With a huge library of samples, multisamples, rhythm patterns, drum kits and loops, it covers 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 matching fills, intros and outros. You can choose from multiple production styles such as the MIDI Command Method, the built-in sequencer and jam mode. MSoundFactory users can also download additional drum libraries (add-ons) for free.
MGuitarArchitect
MGuitarArchitect is an all-in-one guitar chain simulator built on MTurboAmp and MCabinet. It includes 40 amps, 13 cabinets, 26 stompboxes, 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 such as MTurboEQ, MTurboComp, MTurboDelay, MTurboReverb or MDynamicEQ, you can insert them anywhere in the guitar chain.
