OK, it is just way too quiet around here lately.
So, I quickly put together a little ad lib using the sequencer follow
mode. So what you've got is the Poly 800 playing its sequencer in note
follow mode. The Poly 800 has local control turned off but is
transmitting MIDI to the EX800. Meanwhile, the EX 800 is using a
different patch that is set to portamento mono mode. So the Poly is
playing the sequencer and is shifting played notes up and down
according to the lead notes which are being played by the EX 800.
Enjoy!
