Hi All, hopeless newbie question here - I opened a new 'songwriter' project on ProX and recorded a guitar part over the basic pre-recorded drum track but the two tracks are MASSIVELY out of sync. Any suggestions? Gear: electric guitar into Yamaha THR10 amp, then direct to iMac via amp's USB. I've also tried thru Sapphire, same issue. Makes no difference if I monitor via iMac, THR10 or headphones. Thanks to anyone who can help.
