Cal, Take what I am about to say worth a grain of salt. I used to provide support for notebook computers (same principal would apply to a desktop). Many of our computers lacked a serial port, but people with older PDAs, that only synched through a serial port would try a USB to Serial adapter. The problem with a USB to Serial adapter, in many cases, is that it doesn't actually create a serial controller. Rather, it provides a method for a serial signal to reach the computer through the USB bus. I say that, to say this. a PCMCIA, or PCI serial card probably would work, as I imagine that it would actually have a serial port controller that would be recognized by the computer, as opposed to providing an alternate path for the serial data to reach the computer.

I tried a serial-USB adapter, but that didn't work and am wondering if I should even bother trying a PCI adapter or just get an older second-hand PC. I love the DecExpress and would prefer to continue using it as my main synth. Thank you.
