Hi,
I wrote the message below to a list member (Marc) but my e-mail gets
bounced back. It concerns an off-list message Marc sent me re last
week's thread "evolver and poly questions?". I thought it appropriate
to post it here instead.
Best to all,
Tomas.

Hi Marc,
It works for me. I do the following: I have a Mono Evolver Desktop, a
Poly Evolver Rack, and a MIDI controller (BCR 2000) all attached to a
MIDI interface (AMT8), which talks to my Mac running Logic Pro 6.
Since the BCR does not send sysex, I cannot send the sysex string
F0 01 20 01 51 xx F7 (where xx=00 to 03, depending on the part of the
PER I want to select)
directly from it to the PER. Instead I send a MIDI CC message from the
BCR (I use CC 58 on channel 1, but of course this doesn't matter much)
into Logic, which translates this into the sysex string above (the
value of CC 58 determines the part 00 to 03). In Logic I use a
transformer object to do this translation, but also the MIDI Solutions
Processor should be able to do this.
On the other hand, if you have a MIDI controller which does send sysex,
you can directly send the sysex string from there. Every controller
that sends sysex should be able to do this. The problem with some MIDI
controllers---Novation?---is that their knobs are unable to send more
than 128 different values, while some of the parameters of Evolver have
more values to choose from. This is not a problem here since we only
have four values (00 to 03).
If you do not have a MIDI controller, but you do have the MIDI
Solutions Processor (or something else that will turn MIDI messages
into sysex), you could also do something like this: the MED (or MEK)
sends out a bank message (CC 32) when you change banks, so you could
translate this CC 32 into the sysex string above and let the bank (1 to
4) determine the value (00 to 03). In this way you could select a part
on the PER by selecting a bank in the MED. (I tried this using Logic as
a translator and it works.)
This would also work with any other CC messages which Evolver sends
out, but the bank messages seem appropriate.
However, in each of these cases, when you are changing parameters of
the PER by turning knobs on the MED (or MEK), the parameters of the MED
will be changed as well, so that when programming the PER via the MED
this way, you 'lose' the voice of the MED.
Hope this helps.
All the best,
Tomas.
