SampleScience released Stylo Synthesis for free
Stylo Synthesis is a virtual recreation of the famous portable organ from the 60s. Most stylophone plugins and libraries use very short samples that don’t reflect the unstable nature of this instrument. For Stylo Synthesis, each note has been sampled for 5 seconds to capture these magic imperfections. The result is the most accurate stylophone emulation, preserving the attack and sustain of the original instrument.
