Out of interest is there any way to control volume?
Not trivially... there are some assembly programs from the Assembly Lines zine that claim to support some limited volume control, but I've never got round to trying them...
Alternately you could use DAC.522 to playback actual samples. You could even dynamically generate the samples if the waveforms are simple enough.
