Bending the MT240
This is a great keyboard to bend because there are SO many possible bends and most of them are awesome. I usually make a patch bay where I connect all of the points shown in the picture below to a bunch of banana jacks.
A patch bay system is great because it allows you to explore all of the potential connections over time. If you like having switches, just wire the leads of a toggle switch to two banana jacks then wire in your favorite connections for quick activation. It’s a good idea to label the rows and columns of patch points. Then you can keep track of the bends you find.
I have found that LOTS of cool effects can be found by using potentiometers to limit the resistance between patch points. Use LOW value pots. 100 ohms are good. 10 turn 100ohm pots are great. The best configuration is a single turn 100ohm pot and a 10 turn 100ohm pot in series. They work as a coarse and fine tune and let you tweak the hell out of the effects you find.
Linking 2 or more MT240s
The clock speed of each keyboard is controlled with a crystal. You can sync the two keyboards by connecting them both to the same crystal. The pictures below show you how it’s done. This allows you to perfectly match the tempo of both keyboards and make some really rich overlapping rhythms.
