More turntable research.
“The AVDJ deck is in fact a steel deck plate that can be fitted to any Technics 1200 or 1210 turntable in less than 10 seconds, - the 1200 and 1210 being the ubiquitous, industry standard deck found in literally all clubs”.
Looking at the videos, they appear to be using an optical sensor (maybe from a hacked mouse). This is an approach that VScratch also used. Putting the sensor on the end of an arm though is a nice touch. It does appear that using an optical mouse has quite a bit of latency between the scratching and response. Does anyone else have any experience of this?
