BLEASS Delay is the ideal tool for adding depth, movement and interest to your mixes. Whatever style of music you produce and whatever instruments you work with, its versatility and ease of use help you achieve perfect results with the minimum of fuss. Echoes are just the starting point. The integrated frequency shifter and dual filter give you deep control over the character and sound of every repeat, so you can achieve with a single plugin sound effects that would otherwise require a complete plugin stack and complex routing. BLEASS Delay also includes three LFOs, one each for the delay engine, the frequency shifter and the filters. As well as classic modulation effects such as chorus and flanging, these dedicated LFOs are ideal for creating exciting sound effects and epic, constantly-shifting soundscapes. FEATURES • Delay time synced to your host tempo (note values, including triplets) or set freely in milliseconds • Ping Pong mode with adjustable stereo width • Frequency shifter applied cumulatively to each repeat • Low pass and high pass filters: drag on the graph to set cutoff and resonance • Three LFOs, each with depth, rate and stereo phase offset up to ±180° • Feedback from a single echo to infinite repeats • Dry/Wet control • Preset manager with factory and user presets, plus a preset generator • Clear single-screen interface on iPad and iPhone WORKS WHERE YOU MAKE MUSIC BLEASS Delay is an AUv3 plugin. Load it in GarageBand, Logic Pro, AUM, Drambo, Koala Sampler, Loopy Pro or any other AUv3-compatible host. Your saved presets are available in all your hosts. A standalone app is also included. BLEASS Delay is also available for macOS, Linux and Windows (VST3 / AU / AAX). More information at www.bleass.com/delay

K7D is a powerful and affordable, vintage tape delay effect plugin for iOS. K7D recreates the hardware echo machines of the past using Imaginando’s signature style of obsessive analog emulation, but with an enhanced level of control from a sleek, modern interface. Using this approach allows a whole new world of creative possibilities, while still retaining a warm, full-bodied analog sound, bursting with character and personality. To give K7D it’s distinctive analog flavour, we studied and analysed the tiny details of what makes classic hardware delays great, and painstakingly recreated every subtle nuance for a fantastically authentic sound. Available as a standalone app and audio unit plugin, you can use it digital audio stations for iOS such as Garage Band, AUM, Cubasis, Auria, Audiobus, etc. Features - 1ms to 1 sec. dual playhead analog modeled delay with noise, tape distortion and mechanical vibration models - Modeled microphone input with pre-amp saturation - Normal and Ping Pong modes - Optimized gain staging and saturation algorithms for very musical results - Delay time spread between heads and stereo width control - High pass and Low pass filter on feedback path - Powerful LFO bipolar time modulation with multiple waveforms (sine, triangular, saw, square, sample and hold and filtered sample and hold) and possibility of inverted LFO phase on second play head (for added stereo imaging) - Delay time syncable with BPM - Possibility of delay time modulation via incoming midi notes - Oscilloscope visualisation of audio waveform and LFO waveform - Built-in patch manager - Audiounit compatible
