Hi, I have downloaded some external drum loops that are not mac loops and I dont know the correct bpm of it but Im running it at 80bpm. I am using alchemy in GB too on another track and have selected a great bass arp but in alchemy I also dont know the tempo of the arp as it dosent tell me anywhere and I cant change the tempo of the arp as far as i can see within alchemy so how do i sync the tempo of the two tracks in GB. I have altered the tempo of the drum loop faster and slower to try and locate the Bpm of the arp but I cannot get it exact. Any help appreciated. I just want to be able to play the arp on the GB keyboard in time with the drum .
