Logique Analogique – Simulation of a real circuit board on iPad
Logique Analogique is a simulation of a real circuit board that includes an 8-bit binary counter, analog implementation of logic functions, and 4 channel, 1-bit sound generation.
To quote the developer, “The Logique Analogique sequencer consists of an 8-bit binary counter and four tracks which generate pulse waves when a user-defined majority function depending on the counter bits is true. Switches which select the counter bits (or their logic inverse) and a threshold voltage define the majority function. The output is calculated as the XOR function of the four tracks’ signals, which produces a ring modulation like effect.”
“Complexities aside, this app creates incredibly powerful sounds, with a seemingly endless amount of rhythmic possibilities. The sounds can be layered to create ring modulation type effects, with both pitch and threshold control to further shape the sound. The sequencer makes it possible to create evolving patterns or complete songs, using the tap & drag method to easily create your sequence. I would suggest starting slowly with this app, to hear the effect of each switch or dial, but then dive in and explore. It has to be noted that this app does not offer any method of recording yet, but both MIDI and Audio Copy are currently being considered for the future. Despite these missing necessities, I have to say that I’m incredibly impressed with the power of this app, and for the first time, I’m willing to connect my iPad to another source to record my creations. I haven’t found another app that creates such intense sonic delights as this does. I’m so taken with Logique Analogique, that even without recording or MIDI, I still have to rate it … A Killer App!”
