[sdiy] Microcontrollers for eurorack use... What to use?

CrossWorks for ARM is a complete C/C++ and assembly language development 
system for Cortex-M, Cortex-A, Cortex-R, ARM7, ARM9, ARM11, and XScale 
microcontrollers. And when we say complete we mean complete -— 
CrossWorks for ARM is packed full of features such as:

     CrossStudio Integrated Development Environment. This is our own, 
natively built, IDE which takes care of edit, build, download, and 
debugging over SWD/JTAG.
     GNU GCC and Clang/LLVM C/C++ toolchains.
     The CrossWorks Debugger. Our multi-core debugger able to seamlessly 
debug applications built from within the IDE or applications built with 
external toolchains.
     The CrossWorks C Library. This is our own non-GPL and non-LGPL C 
runtime library is designed from the ground up for embedded processor 
applications.
     The CrossWorks Tasking Library, known as CTL. CTL is a royalty-free 
tasking library that provides a multi-priority, preemptive, task 
switching and synchronization facility.
