Velvet Machine (AUv3) melts the characteristics of reverb, granular-style delay… processors in one app, and transform any sound into a fluffy sonic texture. 

Yuri Turov is one of my favorite developers. His synthesizers Shoom and Xynthesizr have been with me for years. Shoom, for example, can make rich, playable drones that I’ve used at concerts. Now Yuri is back with a new universal app, even one with AUv3 support.

Velvet Machine is a new AUv3 effect processor that uses real-time convolution with enveloped velvet noise. The musician does not play with a traditional effect here but one that fits in the experimental area. Sonically, it can be a sound stretcher, advanced reverb, granular-style effect, delay & more. Yuri Turov describes his development as a sonic texture generator.

You can quickly see the flexibility of the app in the video below. A mobile musician who has found his sound home in the ambient, drone .. area can no longer ignore this lovely app. I guess. However, the fun has its CPU price. Valvet Machine is CPU-intensive and requires a minimum of 5th Gen iPad, iPhone 6S, or 1st, Gen iPhone SE, to run a single instance at maximum settings.

If you have a current iPad or iPhone, you shouldn’t have a problem with the app. And yes, an iPhone is also an effects processor, probably the most powerful on the market. Unfortunately, not a lot of musicians benefit from the power of your phone that you otherwise carry with you.


  • Flexible volume envelope with arbitrary number of segments and curvature
  • Effect time ranging from 100 ms to 10 s
  • Response density adjustable from 1 to 2000 repeats per second
  • Predelay up to 500 ms
  • High cut and low cut filters for the effected signal
  • Mix adjustable from 100% dry to 100% wet with no dry signal
  • Mix Lock to switch presets while keeping the dry/wet mix constant

Yuri Turov Velvet Machine is available now for $5.99 USD from the Apple AppStore. It’s an Audio Unit v3 plugin and requires a compatible host such as GarageBand, AUM, Cubasis, Audiobus etc. The provided standalone app does NOT support the currently deprecated Inter-App Audio.

  1. Thanks for posting about this. I bought it on impulse, alas, I realized I know zero about routing app filters. I’m missing the simple step of how to get an external signal in and out of apps. I’ll try an usb audio interface to lightning adapter, but hoped to use SynthOne. Any primers recommended?
