Yukawa is an AUv3 compatible multi-effects plug-in that combines a multi-tap sequence delay that produces a rhythmic phrase in sync with the beat, a modulatable stereo delay, and a DJ mixer style filter.

# Sequence delay
You can set the volume, pan, cutoff frequency, and resonance for each tap of the delay with up to 16 taps that are synchronized to the beat. You can also set the Damp parameter to gradually reduce the high range or low range each time the delay is repeated.

# Stereo delay
A stereo delay with various functions packed into a simple UI. It works not only as a simple stereo delay, but also as a ping-pong delay that produces the effect of sound moving left and right. The delay time can be specified in milliseconds as well as tempo synchronization. By modulation, you can create a modulation effect sound such as chorus. You can also add negative feedback and distortion or noise to the feedback.

# filter
The DJ mixer style filter can control Low Pass and High Pass Filter seamlessly with one knob. The cutoff frequency can be modulated. Also, overdrive can create a distorted filter sound.

# Routing
On the routing setting screen, you can set which signal is sent where and how much.

# Universal App
Compatible with iPad and iPhone, it has multiple screen layouts optimized for different screen sizes.

# Audio Unit Extensions (AUv3)
You can use this AUv3 Plug-In in a host application that supports Audio Unit Extensions (AUv3).

# Audiobus
You can stream live audio directly to any Audiobus compatible application. See for details.

# Ableton Link
It is possible to synchronize tempo and timing not only with applications that support Ableton Link running on the same device but also with applications running on other devices via the local network. In addition to iOS apps, you can also sync with compatible applications on Mac/PC, such as Ableton Live and TRAKTOR. See for details..

# MIDI Inputs
- Core MIDI, Virtual MIDI, Inter-App Audio MIDI Input
- MIDI Clock Syncronization
- MIDI Controller Mapping

Awesome app!

Just love it! If you’re “thinking” about it, then you should get it. It’s gonna be the special sauce for my boring (at times) drum tracks ;)

And definitely check out Lagrange! It’s amazing too. Haven’t tried any other apps from this dev, guessing they have just as much integrity and quality baked into them. But I kind of have a ton of synths already, so will get them at a later time... But Lagrange, and this FX, definitely recommend even if you’re like me and have a lot of good synths/fx already. Also check out Saturn 2 (from a different dev, but really great fx too)

I Love this!

You know all those ios instruments collecting dust in your device, coz they just aren’t inspiring to play? Well *this* is fantastic for taking those dull, lifeless sounds into creative, new, fun to play directions :-)
