If this machine has a separate CPU and FM synth chip you might be able to do a 'dataline cut' mod where you cut the 8 links between the CPU and Synth that transmit preset data information and replace them with switches. With some switches turned off when you select a new preset sound some of the data for the preset will reach the synth chip and other bits won't causing some unlikely alien noises.

Do a search on the net of the serial numbers of some of the chips to find out if one is a synth chip, if you can find a datasheet it will tell you which pins are the dataline pins.
