I´m trying to build a "poor mans ptz" with a korg nanokontrol midi device. When using its faders as shortcuts for the t-bar or volume knobs in the audio section it works great so I thought I could maybe also use it to control the Zoom and Pan X/Y for a virtual input. In my case I´m using a 4K Input and want to move the virtual input which is zoomed up to factor 3 "live"... BUT: the numbers in the Zoom have a lot of numbers after the "," (sorry, don´t know the english word for this kind of numbers) which can not be controlled via midi, as this only sends 1-127... Is there any workaround for this?

Thanks in advance and greetings, Thomas
