Those newer desktop synths that have 5-pin DIN classic MIDI and USB already have a microprocessor to control the synth engine, and USB, and MIDI. The firmware was written to handle all three, and the MIDI is just a serial port with the correct settings and
code to pass along the messages, in and out.<br>
<br>
Any keyboard controller that has a USB connection built-in will already have a microprocessor, but it might not have a serial port (for MIDI), or if it does have a serial port then the pins might be used for something else, or if they're not used then they
still might be inaccessible under the microprocessor chip package. The firmware would have to be rewritten to add 5-pin DIN classic MIDI if it wasn't originally designed into the product. There's a very small chance that your USB keyboard controller already
supports 5-pin classic MIDI on the PCB, but you'd have to figure out how to wire it up.<br>
<br>
As for your realistic options:<br>
<br>
You could replace your keyboard controller with one that has both USB and classic MIDI (or even one that has only classic MIDI).<br>
<br>
Apart from that, you could design your studio around a device that can act as a hub for all kinds of MIDI: classic 5-pin DIN, ethernet (RTP-MIDI), and USB-MIDI. This option isn't cheap, but then you don't have to worry about adding new modules or devices that
aren't like the rest.<br>
