Nothingexept the midi keyboard if that counts haha
I hope one day you can plug the midi in your head and directly record the music you imagine !!!!! This would be amazing !! Direct BRAIN to Midi 

Piano and harpsichord are my main instruments, though I’ve played enough violin to have a good grasp of the techniques, and play a fair bit of guitar as well. But if you want some sweet continuo playing, I’m your man 
Also Im in a rock band band as songwriter,singer,guitarist and producer
You can check for our last video
http://www.youtube.com/watch?v=95Aebf2XQH8Once every 2-3 weeks I play Juno, Fantom, Motif, Nord, Kronos, Jupiter ,Novation, Gaia,...the list go’s on… Pretty much every synth you can find at your local Music store, dreaming I had them all, but hey!, I’ll settle for my M-audio and Vst’s…Oh! almost forgot, I bit of acoustic guitar around the camp fire with friends and a cold one.
!!!
guitar, bass, sing, and my computer. 
Primarily a tuba, trombone and horn player back in the day, but now primarily keys, guitar and bass.
Saxophone is my main instrument but I haven’t used it here yet! Otherwise, keys, guitars, percussion, vocals, harmonica, flute, whatever it takes to get the track done!
Guitar, bass, mandolin, lap steel, pedal steel, ukulele, vocals, percussion, keys (a little)
On everything that makes sound
I wish 
But most often Guitars (Ac., El.), Bass guitars, Piano, Percussions, Triangle, Wood sticks, Spoons etc. 
Keep on rocking and create some great music!
CHA!
I play the electric, classic, acoustic guitar, piano, banjo, vocals, mandolin and the darbuka ( Arabic percussion)
