Classic FX 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. This application will add brightness and expand the sound space of any musical instruments, synthesizers, drums or voice. Unique and diverse effects with unified control parameters provide convenience and ease of customization, while at the same time plenty of room for individual expression and experimentation. Another unique feature of Classic FX is the Morphing option, based on complex effects matrix transformations, which allows you to control the dynamic transition between any two presets. While this can produce stunning effects, it's a breeze to control - you just need to move a fader or push a button. For more morph experimentation, this app has three LFOs to create more complex waveforms for changing morphs. Each LFO has different ranges, waveforms and can sync to the external BPM.

BLEASS Flanger harnesses the sonic characteristics of classic flanger effects and brings them fully up-to-date with a pair of flexible LFOs, variable modulation routing, an envelope generator and beat synchronisation. Classic flangers are a delay-based effect, and modulate the delay time to create the distinctive, repetitive flanged sound. But with BLEASS Flanger, multiple modulation sources are combined to create detailed, complex and evolving timbral movement within your sound. The addition of an envelope generator, which is triggered by the incoming signal, adds an additional dimension to the flanger effect, making it sensitive to the dynamics and nuances of your performances. The second LFO can take the sonic possibilities further still, with the option for it to modulate the delay’s feedback strength or stereo width. The tonal character of the effect can be controlled easily thanks to the multi-mode input filter, whilst the ability to synchronise the LFOs to the beat of your music allows you to explore completely new rhythmic and evolving effects. BLEASS’ trademark interface design ensures this powerful collection of tools are both easy and fun to work with, so you can harness their sonic versatility without ever hindering your musical creativity. And with super-efficient CPU usage, and compatibility with all major hosts and DAWs on desktop, iPad or iPhone, BLEASS Flanger is the only flanger you will ever need.
