The JAF Collection is an exciting set of digital modeled classic analog synthesizer filters (VCFs) for iOS. The emphasis of this collection of audio effects is professional analog sounding and optimized behavior with touchscreen usage. The collection is exclusively available on Apple devices. The apps and the included Audio Units are “universal”, so they work on iPhones and iPads the same way and also have basically the same appearance and functionality. Note: These apps are so-called “Audio Units” (aka plugins), which usually require hosting audio applications to operate. Although, they come with their own basic host applications, which include for instance Core MIDI connectivity and microphone input, to use the filters out of the box, like external hardware devices, without requiring another host application. The JAF Collection Filters can also act as a synthesizer module due to the fact, that there is an unison oscillator section (VCOs) built in for testing and for live performances. The analog modeled synthesizer has no advanced controls or modulators. It just runs the oscillators continuously and can be controlled by external MIDI messages to snap to MIDI pitches or being automated with the volume controller. The complete MIDI assignment is documented in the MIDI Implementation Chart for the JAF Collection, which is embedded into the main app.

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.
