Hi. I posted a similar question before and got very helpful responses, as usual. Listers report that Dectalk Express (the old synth, not the USB version) can work with Windows 7 so long as it is hooked up with a serial-to-USB connector. However, everyone who replied was using a 32-bit machine. Has anyone yet had success using Dectalk Express with Windows 7 on a 64-bit machine? Thanks.
