Dubstation has been a fixture in dub, electronic, and pop production for nearly twenty years. It emulates the analog bucket-brigade delays of the 1970s and 80s, with their pitch-bending, warmth, and gradual high-frequency loss intact, then adds things those circuits could never do: true stereo dual-time delays, ping-pong, a stereo LFO, and a clean digital looper with overdub and reverse. Sound and Character The bucket-brigade model is the real thing: the high-cut frequency tightens as delay time gets longer, exactly like the original hardware. A low-cut filter trims the bass for the thin echoes of early Jamaican dub. A saturation stage on the feedback path adds analog-style breakup as repeats stack up, and the LFO modulates delay time for chorus, flange, and pitch swoops. Looper and Reverse The LOOP switch turns Dubstation into a clean digital looper that holds the buffer indefinitely and accepts overdubs. This is different from cranking the feedback, which degrades and distorts the signal over time. The REVERSE switch flips the delay memory backwards, and combined with the looper produces reverse loops that hold their fidelity indefinitely. Features >> Single, dual-time, and ping-pong modes >> Tempo-synced or millisecond timing, with dotted and triplet values >> 4 ms to 2 second delay range with X2 switch >> Bucket-brigade modeling with delay-dependent high-cut filter >> Low-cut filter from 100 Hz to 1.5 kHz >> LFO modulation of delay time, 0.01 to 5 Hz >> Saturation on the feedback path >> Tempo-synced stereo looper with sound-on-sound and reverse >> Stereo width control >> Factory and user presets, shareable with the desktop version via XML >> Optimized for low CPU usage on older devices >> Full manual at audiodamage.com

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
