Effects are fun, but I know what you mean about over using one effect. I don’t know what controller you use, but I use an S2 with the Buea Bright mapping and the jog effects are really good and add a lot of variety. There is also a echo freeze effect that works good with loops.
As far as your BPM, when you analyze the track it asks you to choose a BPM range. If you are analyzing multiple genres at once, you need a huge range so you often get half/double BPMs. You can fix this in two ways:
1. Analyze songs of the same genre/similar BPMs together and choose the appropriate range.
2. Manually fix this yourself. When you are beat gridding your tracks and you use the advanced view there is a little tab for “grid”. If the song analyzed at 1/2 BPM (like your example above) you simply click the x2 next to the bottom BPM readout. This will double the BPM number without changing tempo of the track.
I prefer method 2 because I am going to beat grid all of my tracks manually anyway and it is only 1 click to fix it. I spin dubstep sometimes and my tracks analyze at 70 BPM most of the time. I like to mix with the normal electro house I play and I use sync frequently so I always double them up to 140 so I can more easily match up with 126-132 BMP tracks.
I hope this helps.
