I did some bits with gen-1 logue-sdk, the NTS-1 could have been a platform like the OP but the processor is severely underpowered for the price in today's standard and discontinued shortly after.

There sure is, and folks are doing some crazy things with it ..

For example: the Bent[1] and Turbo[2] synths from Sinevibes[3] are incredible.

A perfect example of how the platform was embraced by user-developers and pushed into extremely creative and inspiring territory .. surely other manufacturers will start to take note, and maybe someone, some day, will start shipping their instruments with compilers-onboard, to .. you know .. make it easier for kids to keep the bending going on ..
