Bastl Kalimba

The Bastl Kalimba is an acoustic-digital hybrid instrument by Bastl Instruments that combines acoustic metal tines with a digital synthesis sound engine. It includes internal microphones, touch-sensitive areas, and an onboard accelerometer as part of its physical interaction design. The touch-sensitive areas comprise four front touch points and two assignable back touch points. The instrument preserves the mbira’s two-directional, interlaced pitch structure even when configured in other tunings. The metal-tine approach to kalimba design dates back around 1300 years. Internal microphones capture the player’s interaction with the metal tines.

Technical Features

The Bastl Kalimba uses acoustic metal tines as its primary physical interface while the instrument’s sound generation is handled by a digital synthesis sound engine. The metal tines function as acoustic interfaces and the sound engine employs digital synthesis for producing the instrument’s audio output. Internal microphones are embedded within the instrument to capture the player’s interaction with the metal tines. These components together present the metal tines as acoustic input elements and the digital synthesis engine as the source of sound.

The instrument is equipped with touch-sensitive areas on both front and back surfaces, with four touch points on the front and two assignable touch points on the back. An onboard accelerometer is included to detect movement, and the device can be rotated or gestured with to interact with the onboard engines. The Bastl Kalimba preserves the mbira’s two-directional, interlaced pitch structure even when configured in other tunings. The combination of metal-tine acoustic interfaces, internal microphones, touch-sensitive points, an accelerometer, and a digital synthesis sound engine defines the instrument’s technical feature set.

The metal-tine approach to kalimba design dates back around 1300 years and is the historical basis for metal-tine thumb pianos used in later instruments. The traditional mbira employs a two-directional, interlaced pitch structure. The interlaced pitch layout of the mbira is presented in the source material as a defining structural characteristic of that family of instruments.

The Bastl Kalimba combines the historical metal-tine approach with a digital sound engine. The metal tines on the Bastl Kalimba function as acoustic interfaces while the instrument’s sound generation is provided by digital synthesis.

The Bastl Kalimba was funded through a Kickstarter campaign referenced in coverage of the project around Superbooth 2026. The campaign had surpassed its original goal by ten times, a funding milestone reported in the article. By the time of Superbooth 2026, the Kickstarter campaign was approaching three-quarters of a million euros in pledged support.

The reporting notes that the campaign’s funding total had already exceeded the initial target by a factor of ten prior to the close of Superbooth 2026. The coverage states the campaign was continuing toward the roughly €750,000 mark at the time of that event. No further funding breakdowns, backer counts, or reward-tier totals are provided in the available article content.

“Bastl Kalimba, with its combination of acoustic and physical interaction with fluid digital synthesis and sensing, is a triumph of instrument design.” — Peter Kirn.

“The clever twist in the Bastl Kalimba is that the titular metal tines are acoustic interfaces but that the sound engine itself uses digital synthesis.” — Peter Kirn.

“The best of show at Superbooth 2026 is an easy pick.” — Peter Kirn.

“So Bastl Kalimba has several components:” — Peter Kirn.

“Interface. Internal mics plus touch-sensitive areas.” — Peter Kirn.

“Sensors. There’s also an onboard accelerometer, plus four touch points on the front (owing some history to Buchla and the like), and two assignable touch points on the back — just every part of this you can play on, if you choose.” — Peter Kirn.

“And so you can rotate and make gestures with the device to interact with the onboard engines.” — Peter Kirn.

“There’s no reason electronic musical instruments need to lack physical interaction, or to erase or totally flatten tradition.” — Peter Kirn.

“As I write this, the Kickstarter campaign is trucking toward three-quarters of a million euros — it had blown past the original goal by ten times before Superbooth even wrapped.” — Peter Kirn.

“Just as big-data AI is removing physical interaction, automating music, and imposing sameness, electronic instruments can do the opposite.” — Peter Kirn.

“The truth is, just as we’re finding new ways to riff on the keyboard and keyboard instruments, there are basically endless possibilities for what we can invent here.” — Peter Kirn.
