(In fact I don't know what type 'c' is supposed to do (-64..+64 ???) , as seemingly any SysEX needs to have bit 7 = 0. I also don't know if/how the types larger than one byte will strip off the bits 7 from the multiple bytes ).

Silly me:
Of course here str_getchar does not know that it works on SysEX data, but is just a general string function. So the working of the type attribute is obvious ('c' -> -128 ... +127).
Hence to extract somthing else then unsigned bytes from SysEX, dedicated user code is needed to be done, handling the always zero upper bits of the bytes.
