Do you have to limit any of them other than running out of memory?

I'm adding 50 Chains to the firmware (these being more like "performances" or songs ... a chain is a list of presets that you step through).

Put another way, how many patch changes on a MIDI synth/rig would there reasonably be worst case in one "song"?  I realize some Prog Rockers might have pretty long songs.
