I noticed the upcoming A-190-2 Low Cost MIDI-to-CV/Gate Interface at
Doepfer site:

Would it not be a good to get rid of the range limitation (0...+5V)
That would be benefit when used with large keyboards, computers, wind
controllers etc. Also, it could sometimes make things easier, if the
unit could output negative voltages too.
