Guitarscaper is a generative music app and virtual instrument that’s easy on the ears and fun to play. Launch the app, and with a single tap of the auto-play button, guitarscaper will create evolving and ambient guitar-based soundscapes that are unique every time. While all of the guitarscaper sounds originated from a single electric guitar, many have been extensively processed to create an “impossible guitar” that can morph between orchestral-type swells and ethereal choir-like sounds. Think of it as guitar DNA taken to the next level! Guitarscaper in auto-play mode is the perfect companion for relaxing, studying or providing non-intrusive headphone music at work or on your commute. You can even set a timer so you can fall asleep to its gentle and soothing tones. You can also play guitarscaper as a virtual instrument using the dedicated keypads and performance loop recorders, and tailor the sounds with built-in reverb, delay and “character” effects parameters. And while you’re playing, guitarscaper can lend a hand by adding auto-accompaniment parts and even provides hints for notes it thinks might sound good depending on which notes you play! As a sample-based instrument, guitarscaper currently supports two “moods” – a light mood, based on the E major / pentatonic Yo scale, and a sad mood, based on the Em pentatonic scale. Please note that guitarscaper is not a chromatic or MIDI-compatible instrument, and it is unlikely to become one. You can also record and process the audio output of guitarscaper using any Inter-App Audio host that supports IAA Generators. You are free to use guitarscaper in your own recordings or live events and installations on a royalty-free basis. All I would ask for is a simple credit that includes the name of the app – “guitarscaper”. I hope you will agree the guitarscaper interface, while minimalist and a perhaps a little cryptic initially, will eventually become very easy to use. Please do take the time to read the quick-start guide which can be found on the website. This is also the best place to ask questions, get technical support or report any issues. Happy guitarscaping! *** Please note that this app is now in maintenance / bug fixes only mode as it relies on "deprecated" (by Apple) technology such as IAA. ***
