Igor Vasiliev has updated Classic FX - Reworked classic audio effects for iOS to version 2.2. They say:
Classic FX application is a complete sound effects processor and a mono to stereo enhancer with equalizer, effects and reverb, based on specially designed high-quality processing algorithms and suitable for any kind of audio sources.
In this update a new LFO option has been added for automating morphing between the two effect slots A and B. Now you have three linked LFOs to create more complex waveforms to modify the morphing. Or you can use one LFO for simple automation. Each LFO has two ranges, fast and slow and two types of waveforms. You can set the LFO frequency in beats synchronized with the main BPM, or in seconds. Also you can see the final waveform of all the LFOs on a graph at different scales.
This update brings six new processing algorithms based on reverse delay, saturation and distortion. These new algorithms Back Talk, Bitcrusher, Oversaturate, Gated Echo, Gated Reverse and Shining will give a completely new sound to any instrument or voice, from soft saturation and ambient fuzziness to sharp and hard overdrives and bit reduction.
Complex and integrated effects sound much more varied and interesting than simple effect modules, and will give you the opportunity not to waste time looking for combinations of single effects, but to start creative work with the sound of your instruments right away.
