Seriously needs a program change command.
That is like midi 101, to be able to change sounds is fundamental, try using the keystep 37(or pro) with Roland Zenbeats which also doesn't do program changes(or CC send) fun times not.
My workaround involves keystep into a Roland SH-01A which does send program changes, changing the midi channel of the SH-01A to send the program change to one of my devices with the same midi channel, via a 10 way midi thru box, then changing the SH-01A back to its own midi channel and resetting the patch, hassle, gonna get a Retrokits RK-008.
