![]() ![]() More details on the Piana project are available on the official blog. ![]() Piana is already capable of some impressive effects but it’s not the only effort to turn the Pi into a synthesiser: others are working to port the open-source Pd software synthesiser to the Pi’s ARM processor. “All this – oscillators being alias-managed, bonkers modulation, Moogy roll-off filters, GPU interface with tons of oscilloscope vertices bouncing around in real time – all of this runs on a stock, un-overclocked, 700MHz Raspberry Pi,” project founder Omenie explains of his creation. Named as a portmanteau of ‘Pi’ and ‘analogue,’ the project aims to create a MIDI-addressable software-based analogue synthesiser along the lines of the popular Moog Slim Phatty, with up to eight voices and an OpenGL ES-accelerated user interface, which includes a live oscilloscope and adjustable component connections. Given a little extra hardware and some clever software, however, a Raspberry Pi can be turned into just such a device – and that’s exactly what the Piana project aims to do. “The idea of a self-contained, solar powered BOINC appliance is attractive,” Back writes of his experiments, “as it would not only address concerns over energy consumption but could take a novel and even decorative form, perhaps with a small e-ink screen to display computation statistics.”ĭetails on how to install BOINC on the Raspberry Pi, and how to set up the client, which analyses radio telescope data for signs of alien intelligence, can be found at the project website.Įlectronic synthesisers are incredibly versatile instruments, but they’re frequently priced at the top end of most amateurs’ bank balances. The business of attaching a solar panel isn’t particularly challenging, and Andrew Back has tackled the other half of the equation by porting the Berkeley Open Infrastructure for Network Computing (BOINC) distributed computing client to the Pi’s ARMv6 instruction set. I have one and its nicely built, and its not 'insane' to use a Pi as a light desktop workstation. The Raspberry Pi, however, can run from a solar panel, giving distributed-computing fans a means of contributing environmentally-friendly processing power to their favourite projects. Its a Raspberry Pi 400, its a Pi built into a keyboard like old-school home computers. Those cycles have, however, inevitably come at a cost of increased energy usage. ![]() Through projects like and, computer users across the world have for years been contributing spare processor cycles to create a powerful supercomputer. Another area where the Pi’s low power demands are proving popular is distributed computing. ![]()
