The latest stuff done
Korg ES-1 stuff
Good to have!
OS, software and some banks. One of the bank is empty (very handy if you like to reset your ES-1). The software is from the great Interwebb.

Bonotron - effect unit
A nice effect unit!
It was made by Bonotron, a company that still seems to be active in Karlskoga, Sweden.
Modifications on Doepfer A-110 VCO
Doepfer has a lot of nice synthesizer modules, and they often gives away the schematics. This leads to a lot of modification being made to enhance and enrich the already nice modules.
The A-110 VCO is easy to modify to get softsync and FM-input for a more complete function as a voltage controlled oscillator. The schematic is found here. The electronic part is really easy.
How to mount the extra jacks and switches
To make life simple, I did a small template for the drilling of the extra holes. It is very nice when all the holes are made equal on all VCO´s when making the modification on more than one module.The drilling itself was done by my dear wife, who is a silversmith and good at making nice holes in metal.
Here is the SVG-file. It contains one layer with the scanned panel and one layer with the drill guide. The SVG-file can be opened by Inkscape and adjusted.
A nice picture of the A-110 after modification.
