there are no problems here - it is designed like that, to support polyphonic patches and MPE controllers. you can set midi modules to accept any combination of midi channels and depending on how many midi modules are in the patch and the channels they accept, the voice allocation algorithm will route the notes to the different modules. that is how the polyphonic wavetable patch that comes with the ssp is capable of supporting its voices.
you might have a certain idea of how something should work but that does not mean we have to design it like that. there are many users who all have different opinions and ideas and expectations so be respectful of that and don’t assume we don’t know what we are doing.
you can have multiple midi modules set to listen to the same channel or you can have one module and use its pitch signal for sample selection like i explained elsewhere in the forum. with some effort and creativity as @CNTRLR demonstrates you can go a long way.
