ters. There is only one Effects Unit per Part and therefore it
to applies to all notes on that Part, not specific notes.
On the other hand, a polyphonic destination is one that is
specific to a note. An obvious example would be filter
cutoff frequency. As would be expected of any polyphonic
synthesizer, Kyra has a filter for each voice and it is
reasonable to assume modulation would be per note.
At first glance, only a monophonic source should modulate
a monophonic destination and only a polyphonic source
should modify a polyphonic destination. But that would be
overly and unnecessarily restrictive. Consider a situation
where you would route channel pressure (aftertouch) AND
an envelope generator to filter cutoff. It is a common confi-
guration and it is reasonable to expect it to work. Each
note would have a 'twang' from the envelope generator
modulation but all notes would take a basic cutoff fre-
quency from the channel pressure - so as you push down
on the keybed, all the notes twang brighter. In this situati-
on you have both a monophonic (channel level) modulator
and a polyphonic (per note) modulator routed to a poly-
phonic destination.
This makes sense and Kyra supports it. What would not
make sense is to route a polyphonic source to a monopho-
nic destination. For example, consider the example of
routing velocity to the wet/dry mix of an effects module.
What would it do if you played a three-note chord? It
would route three different modulation values to the sin-
gle effects module which would not do anything useful and
probably cause a glitch. Note that LFOs are also classified
as monophonic destinations - they can have a different
phase for each note but all the other parameters such as
rate and shape are common for all notes on the Part.
For this reason, Kyra does not support routing polyphonic
sources to monophonic destinations but it does support
routing monophonic sources to monophonic and polypho-
nic destinations. Remember that LFOs can be applied as
monophonic and polyphonic sources, simultaneously, and
they will adapt to the destination selected.
If you configure any of these unsupported combinations,
they will have no effect.
To assist you in making valid routings, small icons are
displayed on the Mod Matrix pages (the pages where you
select the sources and destinations). These remind you
what the type of each agent is. For sources, a 'P' badge
indicates a polyphonic source. All destinations are poly-
phonic except those related to LFOs and Part effects.
