Logan String Melody

The lower range also features a simple monophonic synthesiser that is controlled from using faders labelled Bass and Perc.

On the first version, there is a button labelled Orchestra that has hard wired settings and disables the faders for the string sounds.

The second version, the String Melody II introduced in 1977, added more buttons for further hard wired settings.

It has full polyphony with a variable-gain amplifier for each key and a BBD (bucket-brigade device) ensemble effect that gives it the distinctive string synthesizer sound.

The device shown in the picture is the one from trouby; it has an switchable input-jack beside the presets to use the ensemble effect for external signals.
