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

During a routine mining expedition in the outer regions of the galaxy five mysterious boxes of unknown origin were found. Rumours among the workers spread quickly that there was a strange feeling being around these boxes, as if time flows in a different way, not just forward but sometimes also folding back on itself. The miners nicknamed them, the five boxes of reverberation. After the excavation process, to study them more closely, it was decided to transport them back to earth. Rymdigare is part reverb, part noise and drone machine, part quality degrader and part wave shaper. The reverb is built from 5 reverberation boxes where you can control the sound with length and ratio parameters, tail and weight skew parameters and an internal feedback parameter, that could be used to create swelling tails. There is also a built in octave shifter, resonant filter, speed and level degrader and 4 LFO sources for modulating a selected set of parameters, including the LFO speeds themselves. The app can run stand-alone, connecting to other apps through Inter App Audio or AudioBus or it can run as an AUv3 plugin. Map and control any parameter with MIDI using Core MIDI, Bluetooth MIDI, Inter App Audio MIDI or AUv3 MIDI. + Resonant filter (low, band or high pass) + Noise and drone machine + Level and speed degrader + Wave shaper (input and output gain) + Reverb (length, ratio, skew, tail, feedback and type: free, bpm, tuned) + Reverb random variation controls + Octave shifter up and down + Planet orbits (LFO: double tap on parameter controls to map) + Inter App Audio, AudioBus and AUv3 + Map Midi CC using Core MIDI, Bluetooth MIDI, IAA Midi or AUv3 MIDI.

Verdict

The call

The clearest difference is update cadence: rymdigare at every 2 weeks against K7D's every 3 months. rymdigare also leads on chart position (#176 vs unranked) and iOS requirement (9.0 vs 17.0). K7D's advantage is price ($3.99 vs $4.99). On rating, review sentiment, ratings volume and ads there is nothing between them.
