Bastl Instruments launches Kickstarter campaign for experimental Kalimba synthesiser

Bastl Instruments, a manufacturer recognised for its unconventional audio hardware, has launched a Kickstarter campaign for the Bastl Kalimba. The device is an experimental synthesiser engineered to be played like a kalimba, or thumb piano, yet it relies on a physical modelling and FM synthesis engine rather than acoustic resonance to produce its primary sound.

The instrument utilises touch-sensitive tines that function as velocity-sensitive triggers for the internal synth engine. While the tines are designed to be plucked or tapped like a traditional kalimba, they do not generate significant acoustic sound themselves. An internal microphone can be blended in to provide a subtle layer of acoustic texture, but the sonic output is predominantly driven by the digital engine which combines physical modelling with FM synthesis.

Developed over a period of more than three years, the Kalimba represents one of the most challenging projects the company has undertaken. The device offers a wide range of sonic capabilities, extending from pluck sounds to atmospheric pads. It includes built-in effects such as delay, reverb, distortion, bit crushing, and tape emulation, alongside multi-mode filters and a simple arpeggiator.

Unique features distinguish the Kalimba from standard synthesisers, including a looper capable of time-stretching, reversal, and destructive processing through the effects chain. The instrument also incorporates accelerometer-based controls that allow users to manipulate timbre using effects designated as Soil and Wind. Additionally, two programmable touch points on the top surface enable users to assign specific parameters, such as pitch bends or the size of the reverb effect.

Bastl Instruments is currently running the Kickstarter campaign to gauge market interest before committing to mass production. The company, which has a long track record of delivering niche music gear at scale, noted the project's complexity during the development phase. This approach allows the firm to validate demand prior to manufacturing, a common strategy for hardware developers on the crowdfunding platform.

Final specifications, pricing, and shipping dates remain unconfirmed as the campaign is in its active phase. While the company suggests it is assessing interest to inform production decisions, the extent to which the project will proceed to full mass production or remain a limited run is currently unknown.
