Are there any MIDI keyboard sound modules that can save patches that are easily played and switched back and forth live?

I use an Alesis Harmony 61 Keyboard and looking for a hardware device that could store and save, and easily retrieve my patches and sounds.

If you live in the USA go to any Guitar Center store. If it exists they will have it.

just about any midi sound module will do that, a PC will do that with a good sound card and software
