Modular Multi FX plugin in the works 2026-05-25T20:13:14+00:00 fx.jpeg Hey I have been working for a while on a plugin I wonder there is any interest for this It's a modular audio effects design environment built around a visual node graph. It lets users create custom signal-processing chains by adding modules, connecting audio/control/modulation signals, and shaping parameters directly inside an interactive editor. I know I know! It's been done before, but I think I have something good here. I have designed every module carefully and let's just say to me it sounds pretty similar to what's out there. The reason I did this was I was angry about being limited to the constrained parameters of the existing plugins and they sometimes didn't sound right to me. It really started with that I couldn't get reversed delays how I wanted them. The knob should have had an 11. Well now you can. And the modular environments were missing features, or were geared towards something else. Annoying when a flanger doesn't get deep enough, and you just wanted to push it a bit further. :D So I used my 25+ years of software engineering experience to create this. So Technic Lego for effects, but not molding your own plastic, and not Duplo either. :D The current version already has the graph editor, patching, parameter editing, automation integration, preset save/load, and a growing set of DSP/control modules. I’m planning a separate control-panel/front-end view too, so a finished patch can have a clean interface while the modular graph remains available for deeper editing. The idea is that you shouldn't be constrained! You can even modulate with audio inputs at audio rate if you so wish. It's per-sample processing so feedbacks are handled well, and performance seems to be comparable with commercial plugins producing the same effect. It will of course use a bit more given that it runs per sample and not per block, and the fact that it is run time modular. But the overhead seems negligible --> Alpha Testers wanted for Windows / PC <-- :phones: :help: Features Visual node graph for building custom effects Audio, modulation, and control signals as separate patchable domains Modules can expose parameters directly in the graph Host automation support Macro/control modules for driving multiple parameters Preset save/load Zoomable/pannable editor Module selection and inspector-style editing Dynamic modules with variable numbers of inputs/outputs where it makes sense Audio-rate and modulation-rate processing paths Feedback-aware graph compilation, per sample processing (allows creating custom flangers, choruses, and reverbs by inserting modules in the feedback path) Stereo and multi-channel routing support Layout tools for keeping larger patches readable GPU-based rendering with optional catenary cables like Reason (with the option to switch between normal and GPU-based rendering for now) Modulate any parameter with audio / mod source through a audio -> control bridge Tempo sync for time-based/modulation parameters with grid selections (dotted, 1/4, etc.) Patch Browser Planned features Undo/redo Dedicated front-panel/control view for finished patches MIDI input/control More modules Better patch organization tools More performance/workflow polish, especially on the UI Nested Submodules Preset Variations (similar to Nord Modular, allowing different presets on the same patch without duplication) Current module categories I/O and routing Audio inputs/outputs, channel routing, utility routing, split/merge style modules. Mixing and level Mixers, stereo mixing, gain/level utilities, panning/spread-style controls. Delay and time-based effects Basic delays, modulated delays, stereo delay structures, multi-delay/tap-style building blocks. Pitch and modulation effects Pitch shifting, pitch-modulated delay structures, chorus/flanger-style building blocks. Filters and tone shaping High-cut/low-cut style modules, tone shaping, resonant/character filters, general filter utilities. (even has MS20 filter which is a favorite of mine) Diffusion and space Diffusor/allpass/chorus-like building blocks for building reverbs, smeared delays, ambience, and spatial effects. Modulation sources LFOs (can sync to each other, polarity, offset ++) and modulation generators for moving parameters and audio-rate modulation targets. Control/math utilities Add, multiply, scale, invert, distribute, and shape control/modulation signals. UI/control modules Knobs, macro controls with selectable step size, parameter-style modules, and eventually front-panel controls. Dynamics Duck, envelope follower, amplitude modulator Bridges Audio / mod to parameter control External/User Pure Data module. Load your pure data file, add a manifest for mapping to my graph system, and you can either prototype your own effects and use other people's effects inside my engine The goal is not to replace every normal plugin, but to make an environment where you can build the kind of effect that usually does not exist as a fixed plugin, or take a familiar idea and push it much further. ;) Samples : pitch shifted stereo delay with LFO controlling the pitch: https://www.dropbox.com/scl/fi/baifsxm7dho3c7gx947vz/presentation.mp3?rlkey=gvzwty53cbphkb2cb4ivn0g5c&e=1&st=kei2e8lu&dl=0 Reverb - diffused modulated delays https://www.dropbox.com/scl/fi/t2b5jj7bv5oritajy0mnu/presentation-002.mp3?rlkey=2owd90nsrby3nbw7nonsa3nhp&e=1&st=xuog9v2g&dl=0 2026-05-28_04-39-10.gif Ad0 https://www.kvraudio.com/forum/memberlist.php?mode=viewprofile&u=7285

having a blast so far with this alpha. a connection matrix could be handy, instead of, or in addition to, the oldskool Reaktor modular approach.
What i really love is the config freedom of delay (time) lengths
