the better sampler you want, the more complex it can gets

IDK, just assuming. Of course that latch chip could be replaced with a set of transistors per each D/A resistor line input. Well both should prevent most of digital ports flaws

perhaps thats why some ADC chips require some negative voltage pin too, to get the full scale of D/A conversion circuitry

....to the actual DAC circuit. Gains higher quality for the sound, as well as the "zero voltage" bias should be tad compensated for the best result of the samples. Otherwise the resulting values never get linear enough when sampled

digital latch is a good idea because they should give out more steady output voltages, i've seen that the voltage stages can differ too much between PC or c64 physical port's pinouts. That latch must be then... signaled, when to forward the signal

((on resistor DAC)) - 8 bits sample bus needs 16+1 resistors of "ladder" connection.

(digital line transitions = momentary stages causing erraneous, momentary high freqs)

Agemixer (03:04:06)
that kind of stuff.

also a high freq filter cap could be needed for DAC (additionally), filtering the port digital transitions to the gnd.
