As a rumor Solid State Music (SSM) was aware of this drawback and developed
a new SSM2044-compatible circuit named "SSM2046" which should have a 10dB
better control voltage feedthrough. But it's quite impossible to find more
information about this circuit and I have never seen an exemplar of this
circuit.
