the Conductor selects the parts the keyboard plays directly then the panel memory saves them. Press the panel memory to set up the overall conditions, R1 is already selected as Pan Flute, my suggestion was merely to press Conductor R2 which gave a pleasant acoustic guitar for the rhumba, then holding SET in the centre of the panel memories press panel memory 1 to save this setup, then saving the new file with current panel, panel memory, composer and sequencer only on page 2 of the save page.

For your alternative registration use the Part Assign buttons above the Conductor. Again press panel memory 1, Part Assign R1 is already selected, select piano 1 octave from the sound group. Press Part Select R2 and choose your vocals, then Part Select L and choose your strings. Now assign which parts the keyboard will actually play with the Conductor, if you want all three at the same time press Conductor R1 and R2 together and then L. Technichord was on in the original registration, leave it on or off as you wish. Now re-save the panel memory as above and then re-save the file to permanently keep your preferences.
