Virtual Gesprächskonzert / Meng Qi, China
Judging by the size of China, it's not really known for synth design, but Tian Jin Qin developed a ribbon synth https://youtu.be/t31IoRkIn7Y around 1978 that still looks quite unique and hyper-modern today.
Beijing-based musician and designer Meng Qi first attracted attention with his Eurorack and banana designs in the mid-2010s, and he also teaches sound synthesis, electronic musical instrument production and creative programming at the Shanghai Conservatory of Music and the Xinghai Conservatory of Music, among others, and frequently gives workshops and lectures on musical instrument making.
What stands out is his personal approach to conceiving and implementing synthesizer systems primarily as playable musical instruments. The analog Wing Pinger and the pocket-sized digital resonator, Wingie, are two instruments in their own right that show a great deal of respect and awareness for designs by Serge, Ciat-Lonbarde, Lorre Mill and Rob Hordijk, but can also be easily learned as instruments without ballast or prior knowledge, conveying a directness and joy of playing that is so rarely found.
Meng Qi started Synthesis Minority in China a few months ago, a podcast and platform in Chinese. You can find his music on Bandcamp.
