I have a Raspberry Pi computer and one of these :
https://www.serdashop.com/waveblaster
I want to write midi data using Python ( a programming language )
on the P.C. ..... and send it to the module via USB .
I need something that appears as a serial com port ,
or disk , or ??? and will drive the module with the right baud etc .
Any help appreciated ....... :D

Only the Raspberry Pi Zero (W) has an USB OTG port that can be configured as a USB device. All other Raspberry Pi models work only as a USB host, i.e., the cannot be connected to a PC.

The simplest solution might be to use a separate USB MIDI adapter. (But then you do not need the Raspberry Pi at all.)

On the RPi I can open a USB serial port with baud 31250 ...... Presto !
I was surprised ..... I was expecting the Pi would not do that baud rate ..
Maybe you have a strict requirement for USB in your scenario, but my advice for connecting two computers is always using a network option. Your Pi probably has Ethernet and/or WiFi available, like your PC, so my choice would be ipMIDI or RTP-MIDI.
