Want to reinvigorate this point, as having just got the V Collection (for others mainly) have found this to be almost unusable on my 24" 1920x1200 screen - the labels and controls are simply too small. It would be really useful if you provided the option (at least on CS80, ARP2600 and Modular; maybe some others like Jupiter) with the ability to "magnify" the size, even if only in fixed intervals of, for example 100%, 110%, 125%, 150% and 200%.
I would hope your plugins use some shared libraries for the GUI side of things, so this should be something you could implement at that level.
This is becoming even more important as we move towards both even higher resolutions screens and also the support for touch at 1028p and above, where these sizes are simply unusable.
