Other key parts include the LM324, LM723 and OpAmp. By type, the board carries 38 resistors, 13 connectors, 11 capacitors, 6 transformers, 4 ICs and 2 switches.

It belongs with the audio designs in this gallery.

From the project

Knock-off of the Elektor Formant Synthesizer project with the initial goal of being quasi-authentic and secondary goal undecided. Probably tweaks of some kind.

- Both IS and IOS are optionally bus assignable. Beware of loopback assignments. - IS is normalized to ES. Plugging anything into the ES jack breaks that normalization. - Regardless of IOS selection EOS is always present at the jack.
