Either that second cup of coffee helped, or I need glasses !

I rechecked the data strings and the offending digit was the first one after each step value (ie the second byte) - How I missed it I don't know !


Now that phase 1 is complete, its time to move on to phase 2. Uploading the data sequences via RS232 comms..... time to read the manual

And before you ask what phase 3 might be... its Music triggering.... Time to go searching for a circuit that will provide either a beat pulse to trigger the stepping of the pattern, or some form of filter so I can produce a 4 channel sound to light with RA0 & RA1 triggered by the bass, RA2 and RA3, lower midrange, RA4 and RA5 upper midgrange and finally RA6 and RA7 treble
