Taking this thread exactly as it comes and without mentioning the obligatory 'fix these things first' - enter list. Which i'm not against as Arturia do have a list of things to address and it's getting bigger with the more stuff they release, however.
Roland Juno 106 has to be the next one, in fact i'm not sure why it's not been done. In the range of the Prophet and the Mg etc the Juno 106 is a classic. Far cooler than the the Jupiter 8.
So, Arturia.. Please, please… Do the Juno 106
As well as fixing Spark of course.
