complicated tunings/feature request

[Hanno <shaftoe nurfuerspam de>]

There are some very complicated tunings out there. For example tunings which 
have up to 72 frequencys for one ocatave. I have an certain idea how to map 
this but dont know if it can be done. 

For to do this I need that meta-modul which can give information about the 
last note that was played and the note before that. This certainly only makes 
sense in monophonic mode i.e. if the number of voices is one. 

Some of the tunings could be switched on from the intrument (hey, another 
feature!) if the melody for example goes down (means: melodic direction means 
the delta of the last two different notes) some of the tunings depend on the 
last note that was played (for perfect quint/quart/terz steps for example). 

So for short there is the need of two possibilities for an instrument:

1) in monophonic mode
a) gather info about the absolute last played note
b) gather info about the melodic direction
c) gather info about the relativ last played note
d) gather info about the ocave-relativ last played note

When we are monophonic it would be very nice to have the glissando and 
portamento effects. 

2) in polyphonic mode
a) gather info about current played cords (??? Im not shure how that can be 
done)

I dont know if anyone here plays strings but I do. And I can say this for 
certain: when I play violin I have two tunings: one if im playing upwards and 
one if Im playing downwards. The halvetones are higher when playing upwards 
and lower when playing downwards - ANYTIME.
So this is a bit more then just an academic feature. It is simply not done 
nowadays because up to now we had no computer/synth/key-instruments that are 
intelligent enough for this. 

But if we have it, it would be a feature that sets us WAY AHEAD of everything 
there is on the market.
