Sometimes form is equally important as function.
I love the style! you could try to put the Sequencers on the upper left and right corner instead of the blind panels. Then the patch cables don't go that far and around your whole rack. What do you plan to use the CV Pal for?
CV pal is the link as far as note voltage and gate from the external sequencer (Logic). It can also be a modulation source with Logic providing external MIDI control. The MIDI part is of course emulated as this is a USB interface, but in practical terms it is the MIDI to CV/gate converter. As it only works with the USB 5V DC source, the keyboard tracking is limited. But I barely know how to play a keyboard anyway, so im happy if it tracks a few octaves.
