PO-35 Speak - transmission of audio material (samples, sequences) in digital form

I have been the owner of PO-35 Speak for some time. In general, I got to know its possibilities. I still wonder why it is not possible to transfer audio material (samples, sequences) in a digital form to another device (PC, MAC, etc.). To transfer created material it should be sampled losing quality. Since it is possible to create data copies (write + sound key) and restore them again (record + sound key), you can certainly transcode the data of audio samples in some way. Does anyone have any knowledge about this?
