I know it's not really why this thread exists, but I thought I'd mention here about the Future Retro Mondovox. Fully sick chord splitter for monosynths (primarily) as well as being a very versatile midi router. I have feeling you could split your drumtrack from your BSP to your Volca Beats/Electribe 2 and more!
Also, Yamaha RY30 will thru/out notes it receives for different instruments on a single channel via different channels depending on the individual routing you make for each instrument in the RY30. Takes a good amount of time to map all the sounds but quite worth it, especially for multitimbre drumsynth triggering (not to mention the RY30 drum sounds are super versatile with resonant digital filters that are way ahead of their time).
