AFAIK these can’t be assigned to a MIDI-function. However it would be possible to hook the driver of the nanoPAD and then use these buttons but thats too much work for too little use.
You can assign them to a single Scene which should be ok as well if you need the function.
We have just heard the sad new from Panasonic (the manufacturer of Technics) that production of the world famous Technics SL-1200 and SL-1210 DJ turntables will stop at the end of February 2010. This marks the end of an era - Technics have been the industry standard for over 35 years with this turntable and the SL-1200 is synonymous with the DJ culture. It has been released and re-released over 9 times with different models and numerous other manufacturers have tried to compete with this deck, but above all, the Technics SL-1200 & Technics SL-1210 are the undisputed number one deck in the world.
