Demo of the Korg MS-10 with a modified MG range, I installled a switch just above the wheel that switches between standard and fast MG rate. The new setting allows the MG (LFO) to go from slightly faster than normal to into audio rate, this allows for a huge amount of new sounds to be created with the synth.
The clip starts with the MG rate set to control the filter at low, then about a quarter then half, etc round to full with the range switch set on normal, then this is repeated but with the switch set to the new extended range. The same again but with the MG set to control the oscillator. Further twiddling ensues, then a sequence with various settings to demonstrate some of the FM effects possible.
Here's how it's done:
Basically it involves removing C34 (1uf), running 2 wires (long enough to allow the switch to be mounted where you want it) from the holes left by it, then get a small toggle switch (on-on type, 3 contacts) solder a leg from C34 to one side of the switch, a leg from a 2.2uf to the other side, the remaining leg of each cap is then soldered together and to one of the wires, the other wire goes to the common (centre) of the switch, there is plenty of room for the switch to be placed above the wheel if you use a small enough toggle.
You can try different values of capacitor for slower or faster times but I found a 2.2uf gave a decent range, another good idea would be to use a 3 way switch with a low/normal/high setting.
