Modular is a powerful sound design tool which allows you to build your own custom synthesizer by connecting different sound modules together. By separating each synthesis process, modules can be connected in any way. You are no longer limited to fixed synthesizer design, you are now in full control of your sound. This is the beauty and power of modular synthesis. Whether you are a professional musician or a beginner who just loves sound, modular offers you an incredibly powerful synthesizer experience.

Modular looks, acts, and sounds like a hardware modular synthesizer to give you features that musicians want such as pulse width modulation, oscillator sync, 4 pole ladder filters, and 1v/oct filter tracking. Traditional modular systems are expensive and out of reach for the average artist. Modular is here to bridge that gap and allow everyone the opportunity to use these powerful synthesizers.

Modular provides modules in every category for free. Enough to build a vast array of sounds. Buy only the modules you need or get the bundle which includes all modules including future modules. Owning a module means you use as many as can fit in the modular rack. You want to build a monster 6 oscillator synth? You can.

What makes modular special is the audio and visual experience you have with it. Beautifully minimal menu systems and interface along with ultra realistic synthesizer graphics are just the beginning. The real beauty is not what you see, but what you hear. Pristine and punchy oscillators that sound great, even at the extreme ends of the frequency spectrum. It starts with band limited oscillators. Not just traditional methods of band limiting, but band limiting that enables each note you play to have the maximum number of harmonics without distorting.

Every detail of the audio has been analyzed to provide you the most amazing sound possible such as buttery smooth filter sweeps and resonance so stable you can use the filter as an oscillator!

Modular goes a step further with connectivity and supports Audiobus, CoreMIDI, as well as AudioShare so that your music making workflow is streamlined and integrated.

Pretty cool


It is worth checking if you are into sound synthesis. You can get some pretty interesting sounds out of this app. There are a few technical things that would make this app a perfect 5/5, such as the interface needs to be refined further, a clear all panels option, and I have been having trouble with the wires as in getting them where they need to be quickly. Thanks!

For those who can't afford a real modular...


...this fulfills the basic urge to patch and tweak.

Not the most logistically simple layout, but some really cool sounds can be had with a little exploring (start with presets if you're unsure and change things methodically).

Obviously this app took a lot of skill to develop. I can't understand why it was abandoned. I've tried to write the developers and see if it could be ported to Mac. No reply. Everyone who uses this loves it and hates it. It's the BEST virtual modular synth out there, on any platform. And it works. You can build whatever you want to. It sounds good. It even looks nice. But it's very hard to actually use. The GUI is awkward, even on iPad. I'm not mad about the patch cables, they are easy to lock and set transparency. But the fact that it doesn't use the whole screen and you can't "fold" sections when making adjustments really makes it a nuisance to operate. If they would just update the SIZING and FOCUS so you could navigate better, it would be a huge improvement. And the pale colors of the patch manager and other backgrounds?? Maddening. Darker colors and better contrast would make a huge difference.

I've been struggling with this app for a couple of years and keep trying to make real use of it but it burns me out after a few minutes each time. It has Audiobus support and EVERYTHING for pro work but it's just impossible to navigate. What a shame :)
