In 1998 Hans Deyssenroth and Julio César Pinillos, a musician from Cuba, created a CD with the program midiVar developed by Hans, that applies midi variations to midi tracks. Julio played percussion on the keyboard and bass lines and montunos as well, but a few bars only. The rest was extemporised by the midiVAR
program. Hans played all the solos, and in some cases, bass and percussion too.
Juerg Scherrer added Conga and Bongo tracks. The result was a very interesting mixture of computer music and live performance in Latin jazz.
