Just one will do the trick... It would be a stand-alone device, not related te the seq. (Very) Basically, you want it do do something like If incoming note = C#, then output C# and +100 pitchbend. If incoming note = D, then output D and -20 pitchbend. etc etc you can store the offsets (pitchbend) which should be applied to each note, in a table - so you can store lots of different tunings by having lots of tables. When/if you know some C, you'll see that the above is extremely oversimplified and that the code would be quite different.
