Melda MTurboFilter

Your custom filter, your signature sound.

MTurboFilter combines the warmth of classic hardware with infinite creative freedom, serving as both a premium library of 9 modeled vintage synthesis filters and a groundbreaking designer tool. Whether you want to instantly load iconic character using predefined options like Fat, Liquid, and Brutal, or program entirely custom filter modules from scratch using its modular algorithm designer, MTurboFilter provides an unrestricted canvas for your sound. Backed by an integrated modulation matrix for its main controls, advanced LFOs, and input-following envelopes, it is the ultimate tool for producers who refuse to be limited by standard audio software.

9 Classic Filters

MTurboFilter features 9 analogue filter models inspired by famous vintage synthesisers. Variable resonance compensation lets you transition from original, low-end-losing behaviour to boosted bass response. Every model can be overdriven to emulate hardware distortion and its unique interaction with resonance. Furthermore, a dedicated feedback control recreates the classic "headphone-out into input" technique, yielding everything from subtle fatness to screaming distortion. Delivering distinct personalities—from acidic squelching to brutal crunch—the interface lets you dial in parameters first, then instantly switch models in context to find the perfect sonic character.

Design Your Own Algorithm

A fully customizable designer lets you construct ultimate filter topologies from scratch. You can mix and match biquad or state-variable versions of low-pass, high-pass, band-pass, and notch configurations with various slopes. Combine these with wave-shapers, compressors, feedback, combs, saturators, and bit-crushers, then map internal parameters to the main controls for seamless interaction.

Modulation Matrix

An integrated routing section sits directly under the 5 main controls, bringing dynamic movement to your filters. Onboard modulation sources feature Melda’s advanced LFOs—complete with morphable, drawable shapes, host syncing, and step sequencers. Meanwhile, customizable envelope followers track your main audio or sidechain input for precise, reactive expression.

Available in MSoundFactory

Integrate MTurboFilter natively as a modular sound design block within MSoundFactory synthesiser creations. Modulate vital parameters with per-voice modulation for unparalleled polyphonic expressivity. Combine the classic filter models with MSoundFactory’s random analogue drift engine to recreate authentic analogue circuitry or build complex, cutting-edge modern algorithms.
