<p style="margin-top: 0px; margin-bottom: 0px;"><font size="2" style=""><span style="font-size: 14pt;">Indeed Pete is correct that the </span></font><span style="font-size: 14pt;">original Electronotes offering was called a digital synthesizer. More properly
it was what would now be called a </span><span style="font-size: 18.6667px;">sequencer</span><span style="font-size: 14pt;">. It sequenced pitches as a programmable melody. </span></p>

<p style="margin-top: 0px; margin-bottom: 0px;"><span style="font-size: 14pt;">Back in 1972 I think we
</span><span style="font-size: 18.6667px;">considered</span><span style="font-size: 14pt;"> something to be digital if it </span><span style="font-size: 14pt;">used digital logic gates etc. and had only two levels at the backbone, as opposed to
</span><span style="font-size: 18.6667px;">being</span><span style="font-size: 14pt;"> analog (op-amps and transistors) with an audio range. My sequencer was of

<p style="margin-top: 0px; margin-bottom: 0px;"><span style="font-size: 14pt;">Today we consider
</span><span style="font-size: 18.6667px;">something</span><span style="font-size: 14pt;"> as being
</span><span style="font-size: 18.6667px;">digital</span><span style="font-size: 14pt;"> if it is
</span><span style="font-size: 18.6667px;">time</span><span style="font-size: 14pt;">-sampled and generally
</span><span style="font-size: 18.6667px;">amplitude</span><span style="font-size: 14pt;">-</span><span style="font-size: 18.6667px;">quantized</span><span style="font-size: 14pt;">, and probably
</span><span style="font-size: 18.6667px;">largely</span><span style="font-size: 14pt;"> </span><span style="font-size: 18.6667px;">software</span><span style="font-size: 14pt;">-based. </span></p>

on to Fourier based </span><span style="font-size: 18.6667px;">additive</span><span style="font-size: 14pt;"> schemes as
</span><span style="font-size: 18.6667px;">pioneered</span><span style="font-size: 14pt;"> by Hal Chamberlin, to primary reliance on software. </span></p>
