Great filter! Smooth controls, automation, sample speed adjust, etc. Dropbox integration, which is fantastic. Get it while it’s free, because I have a hunch the price will jump sooner or later. Probably sooner.

Brilliant Filter ★★★★★

You get what you pay for could not relate to this app whatsoever. This filter kills and does so much more than the description Aptos have you believe. Thank you!

Literally Amazing ★★★★★

This is a great effects app with a great interface. And unlike most free apps, free does actually mean free. The filters are great and when you combine those basic functions with the two x/y pads, smooth sample manipulation via the play head and the ability to apply LFOs to parameters this is better than many paid fx apps.

Nice freebie app, like a dubified version of AUFX meets Stria. In use it works well and reliably with AudioBus, producing some lovely noises when paired with Novation. I look forward to seeing what the makers can offer that might induce payment. Nic

App gratuite mais peut-être la meilleure de la série! J’ai du mal à voir la diff’ avec le waldorf analogique 2 pole filter. Super developpeur

Excellent 🙂 ★★★★★
