Looks great.

What does the auto tune function do?

Is it just a sine tone to tune to like on the minimoog?

At this point I think it’s just there for looks/historical accuracy and serves no functional purpose.

We have spent time about the autotune , it’s a comparator design ,and have created a schematic as a top notch X upgrade.
Don Buchla had already designed the connection for,(there are always on the 259X pcbs,)but its not finished,or perhaps was controlled by a Buchla 300 .
Finally,we have decided to offer a 100% vintage version for this little beast, (with a few pcb design upgrades like a ground plane,no flying wire with the volages ,another trimmer to help in the calibration,etc),perhaps one day we will offer a little autotune pcb to mod the 259X.

Thanks for the update

If the module isn’t complicated enough, Don decided to also put switches on there that don’t do anything!

Look forward to building
