pianoscaper vs StringLab
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
pianoscaper
This app generates unique, evolving ambient soundscapes from processed acoustic piano sounds. It can be used for relaxation, study, or as a non-intrusive musical companion. It also functions as a virtual instrument with performance tools and sound customization.
- Generative ambient soundscapes
- Virtual instrument play
- Performance loop recorders
- Reverb, delay, and character effects
- Auto-accompaniment and note hints
- Royalty-free use in recordings

Pianoscaper 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, pianoscaper will create evolving and ambient soundscapes that are unique every time. While all of the pianoscaper sounds originated from acoustic pianos, many have been extensively processed to create an “impossible piano” that can morph between orchestral-type swells and ethereal choir-like sounds. Think of it as piano DNA taken to the next level! Pianoscaper 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 pianoscaper 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, pianoscaper 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, pianoscaper currently supports two “moods” – a happy mood, based on the G major pentatonic scale, and a sad mood, based on the Dm pentatonic scale. Please note that pianoscaper is not a chromatic or MIDI-compatible instrument, and it is unlikely to become one, although additional moods and scales may be added as free updates. You can also record and process the audio output of pianoscaper using any Inter-App Audio host that supports IAA Generators. You are free to use pianoscaper 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 – “pianoscaper”. I hope you will agree the pianoscaper 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 pianoscaping! *** Please note that this app is now in maintenance / bug fixes only mode as it relies on "deprecated" (by Apple) technology such as IAA. ***
StringLab
This app is a digital synthesizer that uses physical string modeling to recreate the sounds of various instruments, particularly plucked or hammered strings. It allows users to explore acoustic physics and create unique instrument textures through extensive parameter experimentation.
- Karplus-Strong physical modeling
- Exciter Impact and Noise modes
- Resonator objects with feedback
- Frequency Dispersion support
- External live input
- Preset randomizer and manager
- Drag & Drop preset export

StringLab is a physical string modeling synthesizer based on Karplus-Strong theory. It is capable of reproducing the sounds of many different types of instruments, but is especially useful in the reproduction of hammered or plucked strings and other types of percussive instruments. It works by passing carefully crafted waveforms and short bursts of white noise through a series of tuned delay lines. The delay lines have an internal feedback loop with a series of filters to mimic the natural decay of harmonics found in a real instrument. StringLab allows you to discover the character of real-world accoustics, exploring the physics of how materials interact. Many new and original textures are born out of experimenting with the settings, so don't be afraid to experiment and create your own unique and dynamic instruments. Features •Karplus Strong based physical modeling. •Exciter Impact with multiple modes. •Exciter Noise with many envelope driven filters. •2 resonator objects with feedback. •8 bands per object with inversion. •4 Coupling modes. •Supports Frequency Dispersion. •Feedback low/high Damping. •Per object Body Filter. •Pitch Deformity. •External live input mode. •Preset randomiser. •Build it Preset Manager & Favourites. •Search Presets. •Drag & Drop preset export of presets. •Supports Color Sets.
