I for one found that an interesting module.
For what it's worth, though I'm not the greatest electronics expert,
my understanding is the EML does "cheat" on those variable features.
Most of the features you describe aren't true morphs, they are merely
crossfades between multiple outputs (that you don't get individual
outputs for, the pot is your only access). So I think you could
achieve similar results with the A-138e as a 3-way crossfader.
Actually as a side topic which hopefully isn't too DIY and
potentially slightly off-topic. I know the EML used a lot of center
tapped pots. I'm curious if anyone knows where to obtain some or has
had success modifying a standard pot to have an additional center tap
As for the ring modulator, as I understand it it's also considered
fully balanced modulation with 4 quadrant VCAs that respond to
negative voltages. One can vary the index/degree of the modulation
and get varying amounts of AM, a key difference would be with AM you
can hear the carrier while ring modulation more or less rejects the
carrier though not always perfectly. While a lot of newer modules
omit a control for less than balanced modulation quite a few older
ones had it. Serge, Buchla and PAIA come to mind. Generally one can
do one better than EML and get voltage control of the degree of
modulation from zero up to ring. That's one big downside of EML, you
get some very interesting controls via pots but they are only manual,
not VC.
