I would like to know if I am 100% sure of the next thing:
'I'm sure that my patches can work in Aalto CM but with the limitation of one voice.'
Please tell me if I missed something or there are other more limitation.
In general, patches are not always compatible with a previous version. So if your patches are made on an Aalto newer than the equivalent version of Aalto CM, they may not work. I think Aalto CM was equivalent to version 1.3.
