Depends on what you want to crossfade it with …
All algs are single block (I think). Any alg can be crossfaded with another alg if it is small enough – the problem comes when either or both are too big. Since Eclipse has about 100 algs, there are about 10000 combinations, so we don't do a list. You have to run the machine with one loaded, and then as you scroll through the presets, it will show you which are crossfadeable with the loaded one.
