Glad you got it to work!
Regarding getting all the knobs, faders and so forth working, it is all about getting the grip of the MIDI implementation. First and foremost you need to know how UNO Synth implements MIDI, and that you find at the end of the the manual here
https://download.ikmultimedia.com/plugins/Manuals/UNOSynth/UNO_Synth_User_Manual.pdf .
IF your keyboard doesn't do exactly what you want (say, you want knob A to control the Filter Cutoff knob on the synth), you need some way of translating (or "map") the MIDI message from your keyboard before it reaches the UNO Synth. This can be normally accomplished with software like Ableton Live where you can do the mapping there. Ideally you should be able to bring up the UNO Synth Editor as a VST plugin, and simply enter Ableton's MIDI mapping mode, where you click on the control in the editor you want to control (such as Filter Cutoff) and then click on the physical knob on your keyboard. Volia - the MIDI mapping is finished. BUT ... Unfortunately the VST implementation of the UNO Synth Editor has some issues where it only has one MIDI connection, and since Ableton "takes" this at Ableton-startup, the VST UNO Synth Editor will end up in a neverending "WAITING FOR UNO"-state. This kind of mapping isn't therefore straight forward.
*Perhaps* you can get tools like MIDI Translator Pro (

Good luck and please report back how you solve things!
