Batman sends Grayson on a quest so he can continue working on the BatSynth. Can anyone who can identify which synthesizer schematics he has pulled up on the BatComputer!?? Post in the comments!

Sorry, the comment form is closed at this time.
Looks almost like the Korg Monotron. The lower panel looks like a VCO circuit heading in to the "MIX/HPF". Good eyes to whoever figured this out!
FYI the comic is Batman and Robin #34 that was released Wednesday August 20th.
It’s from page 9 of the service manual for the Roland MKS-30 rackmount polyphonic synthesizer (ca. 1983-84.) The Batsection called up by Batman up on the Batscreen displays the voice mixer, which combines the audio signals from each of the 6 voice circuits via TL072 family op-amp. The resulting signal is fed through a high-pass filter (HPF), a simple RC circuit to bleed off high frequencies, user controllable via 100k potentiometer (“Brilliance” control.)

Strangely, while the more common Roland JX-3P keyboard uses the same design, the service manual for that synth was apparently drawn by a difference tech and the schematic for the above circuit was drawn in an entirely different manner.
