## What is TB DualVCF?

Dual VCF - the ultimate dynamic filtering AUv3 plug-in!

Dual VCF adds motion, shape, and colour. It produces evolving rhythmic movement and complex dynamic filter shapes. It contains dozens of analog filter models with that sought-after sound of the 70s, 80s and 90s. Combined with envelope followers and intuitive modulation editors, it provides almost infinite possibilities for creative aural exploration.

Dual VCF features two filter sections, each supporting dozens of low-pass, high-pass and band-pass filter types. Every type is painstakenly modeled after analog filter types found in analog gear, analog synthesizers, and alike, including non-linear filter behavior. Dial in that characterstic 70s, 80s or 90s filter to add some analog flavor to your tracks!

Each filter's cut-off frequency and resonance can be sequenced with an intuitive, free-running or beat-synced modulation editor. Seamlessly switch between sine, triangle, noise, or user-defined modulation waveforms. In addition, these parameters can also be modulated with the built-in envelope follower.

The ToneBoosters DualVCF app captures the microphone (or external sound card) input and processes the signals in real time. To use it as a plug-in, use an AUv3-compatible host app such as Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others. ToneBoosters DualVCF will appear in the list of Audio Unit extensions for effect plug-ins. 

How to use DualVCF as AUv3 plugin in a host program, start your favourite AUv3 host app (Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others) and add TB DualVCF as Audio Unit insert effect to a track or output bus.

### 3/5 — Great sound but UI scales badly

*2024-04-21*

I like the creative possibilities with the two filters which are nice sounding too. It also saves me some space and resources in a big setup. But the UI feels like there was only little effort in porting a desktop version to mobile. I use this plugin in Loopy Pro and AUM where I have a lot of other things to control as well. To use certain buttons I have to scale the window rather big like 2/3 of my 12.9“ iPad. The „help system“ where a tooltip is displayed when a UI control is held for a second also doesn’t work well because the finger covers a part of the text and it disappears as soon as you release the button. Last but not least, the developers website opens when the plugin logo is touched which is really the last thing I need when doing a live show or just being in a creative flow.

### 1/5 — Take a look around

*2023-08-25*

You’ll be seeing particles of gold in the sea of sand! 

Btw, ToneBoosters is a kind of selfish similar to idk multimedia typ of dev.

My apologies, they’ve not reached that level though, but it’s just a a matter of time!

### 5/5 — 加油

*2022-07-19*

加油💪

**Developer response:** thank you!

### 1/5 — Simply does not work.

*2021-08-15*

No use buying this it does not work. Tried it in two sep progs. No good…

**Developer response:** Please contact us to describe the issues you are experiencing; happy to help!

### 5/5 — MUST-HAVE-NO-BRAINER

*2021-02-19*

Absolute outstanding tool, one of the best of its kind on on iOS! Tone Boosters: In the beginning it was a bit „rocky“ with them and iOS touchscreens...they and me hat several battles about it...especially about the iPhone versions, but also the iPad. In the end they refined and updated all their iOS apps really doing everything to make it just HEAVENLY JOY using their apps. Just awesome, don’t think twice: 100% Recommended.

**Developer response:** Thanks for your feedback! We've just released an update for a better touch experience and we'll be working on this in the future as well.

We'd recommend using a simple stylus for control. Our plugins have tons of flexibility and end-user control, and hence we have a lot of controls to edit on screen :-)

### 4/5 — Was looking for audio unit like this for a long time

*2020-11-15*

Great audio modulation plugin. Packed with features, two filter slots, bunch of filter types and a very intuitive UI. My only complain is about the way to set LFO length. It is hard to access. It would be great to have a quick option to set the most frequent options for LFO length like 4, 8, 16 & 32 Beats. Thanks in advance.

**Developer response:** Thanks for your review!

### 4/5 — Two big wishes for 5 ⭐️ 🙏🏽

*2020-08-22*

You’re created the best lfo/filter apps on iOS. It’s such a great app, with so many possibilities and great sounding filters, Congratulations for this🖤
I only had two last wishes, and I’m sorry for comparing, but it would make the work with it a lot easier😬
How about a „snap to grit“ Funktion and a „lfo stepper“ like someone might know from the serum lfo??
It would be soooo wonderful if my wish come true🙏🏽🖤🙏🏽🖤🙏🏽
Best wishes for all your upcoming projects!

**Developer response:** Thanks for your feedback! :-)

### 4/5 — Nice but lacks a simple VCA mode

*2020-06-14*

This app is well done, like your other apps that I appreciate a lot.
Unfortunately, I expected to be able to switch from AD Filterstation to Dual VCF but it's not possible because there is no VCA (level) mode.
I hoped that in "Bypass" mode, the drawn curve would affect the audio level but it doesn't.
Would it be possible to add it?
Shouldn't be too difficult, right?

Thanks for considering!

**Developer response:** Thanks much for your suggestions!

### 5/5 — More......⭐️⭐️⭐️⭐️⭐️

*2020-05-21*

Can't get enough Toneboosters, 
Simply the best quality apps..

⭐️⭐️⭐️⭐️⭐️

**Developer response:** Thanks for your feedback!

### 5/5 — Better Than Fab Filter

*2020-04-18*

Case closed

**Developer response:** Thanks for your feedback!
