Sorry with the VCCIO... this chip (FT230X) must have it at 3.3V (or less) (as you have drawn it, so that is OK). The older ones could have it optionally at 5V.
But than the driver resistor R18 for the LED should be 560Ohms. The diode D12 is not needed.
Data sheet, page 25 http://www.ftdichip.com/Support/Documen ... FT230X.pdf shows how to connect LEDs for RX and TX.
(They don't have to be on the rear panel, just as debugging aid would be very nice. )
Resistor arrays: https://www.mouser.de/Passive-Component ... ?P=1yzu5ah
The "bussed" ones really save space, as they have one common pin for several resistors. Unfortunately we have only one application for them: the four 100k Ohms.
(I don't like to use them, if they don't belong together in the schematic or "function block". )
The 220 Ohms for the MIDI and the 1k (2k2) for the DIN-Sync are further candidates for SIL arrays with separated resistors. (Don't use too fancy types, Mouser carries a lot of them, but Reichelt, Tayda and other more DIY oriented shops, just have a few of them. )
