• Legendary 12-bit resolution
• Perfect modelling of the S950's audio signal path
• Adjustable audio bandwidth (and thus sampling frequency)
• Original steep 6th-order low-pass Butterworth filter
• Stereo or mono operation
• Low CPU consumption
• Supports AUv3 and Inter-App Audio

How does it work:

The Input Gain Knob makes your sound loud’n'proud with the S950’s unique grit and warm distortion. It’s powerful and will help anything stand out in your mix.

The Audio Bandwidth Knob controls the target sample rate and analog-to-digital conversion circuitry with an exquisite, yet remarkably subtle, aliasing effect.

The Filter Knob controls the S950’s infamous steep low-pass filter. Use it on separate elements, or on any output bus or master section.

The Mono switch button is for mono operation (as the original S950) with a 50/50 mix. Great for checking your mix.

I love this effect. I use it on pretty much every track on every song I make. It’s very easy to use and cpu light which is something I always need on my Air 1. It has been very stable as well in every DAW I’ve used it in

Yep, I agree with the previous review.

I use this on pretty much every track I create now, especially for guitars but it can be used on anything really. It is simple and it does what it should do, it also does it very well!

My only complaint:
Poor midi mapping support; there’s no way of mapping the already few knobs available to actual knobs, or midi CC or anything.

Please dev, consider adding this. This app is amazing!

Thank you Dev!

Great effect

5 star don’t come easy from me but I have to say this effect is what I currently needed. It does exactly what it says it does.
