Ploytec PL2 – MIDI Powered Duophonic Synthesizer
Sound On Sound Magazine
by Paul White
Can this tiny box deliver a big sound? At every trade show we come across at least one product that seems to be half barking mad and half genius. This qualifies. First shown in 2013 but now shipping, German company Ploytec’s Pi Lambda Squared (PL2) is powered entirely via its MIDI input and based around some type of lo-fi sound chip. Its output is a simple mono RCA phono connector and it is only around twice the size of a 9V battery. It also has a micro-USB port that can be used to provide power where MIDI bus power isn’t available.
Although all the sounds are based on just four waveforms derived from square waves, and there are only two tone oscillators, the synth ships with 32 factory presets and room for 32 more user patches. One side of the single-sheet instruction manual (which is about the size of a cracker joke) is taken up with MIDI information that allows real-time control over a surprisingly large number of parameters. Further user information is available on the company’s web site (www.ploytec.com).
