I uploaded a plist I am using for randomization here: https://www.elektronauts.com/files/470
This should help you with the high-res parameters, as I included the ranges, defaults, etc…for example if you want to randomize the Filter Frequency, don’t think of it as 0-127 but rather 0-16,256
If you want to send the Filter Frequency value 3000: send cc_msb of (3000 / 128) and cc_lsb of (3000 % 128). The cc_msb should be sent first.
*For the Harmonics parameter, whatever you calculate for the cc_msb, add 37 to it (no idea why they did that)
