Well, there is a way to work around that.

Take a quarter phone jack and solder to it a standard 9 volt power
connector. Attach a 9 volt battery to it and plug it into one side of a mono
volume pedal. Plug the other side to the CV input jack, and you've just
converted a volume pedal to a CV pedal.

I"m not "proposing" this, I'm saying it's the only way to do it that I've
ever heard of.

If you want midi input of volume, whether it by pedal, sequencer, or master
contoller, the midi data has to modulate something because NOTHING is
built-in, like you've seen on other synths. In this case, to control
volume, your choices are either VCA1 or VCA2. As VCA1 is best used for
envelope work, the logical choice is VCA2.

Route midi CC7 (or whatever you're using) to VCA2 modulation in the
modulation matrix section of your programming. Easy-peasy. I don't have
one in front of me, but you can surely figure this out.

IIRC, and it's been over 20 years, guys, the CV input is NOT for a "cv
pedal" as such. It's for a control voltage, not a regular pot pedal as
there is no voltage biasing on the jack. You have to squirt some voltage
INTO it, like if it were connected to a modular system. So it's never gonna
work with a volume pedal.

I'm still confused about this process.....you are proposing giving
up VCA number two, which would be routed to be controlled by CC#7..is there
a block diagram that shows this patch

I actually want to use the built-in CV pedal input to control CC
#2--according to the manual this can be done...anyone
