EVERYTHING SYNTH
File this one under the bizarre. This is a photo for an ad for the "muffler puffs letterpress card" you see sitting on top of the Polysix. The description reads:
"JRackAttack is a project producing a Java-GUI for the RackAttack, a drum synthesizer from Waldorf. With more than 100 parameters but a limited set of only 4 knobs it's quite hard to do the necessary settings in the nick of time. In addition 50 program slots are not enough for me."
