The main theme from "One note samba" by Antonio Carlos Jobim played on two LEGO Mindstorms NXTs. One is used for the rhytm - the other for the two notes. All sounds are the original ones that came with the sets.
I modified the right arm on my Alpha Rex robot and fitted it with a set of sleigh-bells. Then it could play the rhytm for this christmas medley. The songs used are: "Rudolph the red-nosed reindeer" by Johnny Marks, "I saw mommy kissing Santa Claus" by Tommy Connor, and "Winter Wonderland" by Felix Bernard.
"If it wasn't forthe nights" by Ulvaeus & Anderson played on a Technics C600 organ. Outside the picture is a Yamaha PSS-12 keyboard. Automatic rhytm, arpeggiator and bass.
Oxygen XIII by J.M.Jarre played on Yamaha HE8. Rhytm by Roland CR68, and the organ is also MIDI controlling a Roland JX8P synthesizer not visible in the picture.
"Calypso part 1" by J.M.Jarre played on ELKA X-1000 organ. Everything except rhytm is played real-time. This version is somewhat simplyfied compared to the original. But the good part is that I can play it on any organ available (I concidered playing it on the small ELKA EP-8 but the sound of the X-1000 was better suited for this melody).
"Unknown Flight" by Michel Elmosnino originally performed by Milkways. The Roland D-20 plays some of the arrangement via the build-in sequencer. It is also controlling the Korg Poly-800. I'm manually adding some notes from the Roland SH-2000, some chords from the Technics organ and some "swiiiooosshh" effects from the Roland JX-8P.
"Like a Virgin" by Tom Kelly and Billy Steinberg. Everything is played on the Technics organ but in four layers using a multitrack tape recorder - a Fostex model 80 with matching model 450 mixer.
"I've Grown Accustomed to Her Face" by Frederick Loewe and Alan Jay Lerner from the musical "My fair Lady". Played on Mindstorms NXT and Technics SX-C600 organ. The NXT rotates to animate the sound - like in a leslie speaker.
"Magnetic Fields part V" by J.M.Jarre played on Elka X-1000 organ. Automatic rhytm, bass and arpeggiator. The rhytm starts automatically when the keys on the lower manual is pressed and stops when no keys is touched.
