Hi all Love the site and the reviews you have done which ultimatly helped me decide between the S2 and the MC3000. I recently bought the Denon MC3000 and I am chuffed to bits with it. It is truely an awesome bit of kit. I also bought TP2 with it. I have been running TP1 on my laptop for a while and when I installed TP2 on it I quickly became aware that my laptop needs upgrading as it is a pretty old 1.6ghz single core. So I have resorted to using my desktop for TP2 at home. I've looked online for TP1 mapping but with no success. Is the TSI file that is for TP2 compatable with TP1 as I will have to use TP1 on my laptop for potential future gigs until I can affford a new laptop. Also another little question. Will the beat grids I set in TP2 work when I use the same MP3 in TP1? Thanks in advance for your help!
