I use to collect plastic parts on my path, when I walk through the streets at night. Sometimes, somebody lost it, got rid of it, or it accidentally fell off. The best part of this behavior is not the fact, that it wouldn't remain in the nature, or in the streets. Round objects are a good start for example, because they'll fit together, very often. You can create real artifacts, out of these random objects, which are considered trash. But not in my viewpoint, as well as the little toy keyboards, which I use to modify. I don't talk about the new models, which are built very cheaply. The plastic housing is thin and they don't sound so well. The people from the eighties did a real good job, when they created the early Yamaha and Casio product line, of toy keyboards. But they aren't toy keyboards. The only fact, that they sound a little bit harsh and not so clean, doesn't make them obsolete and the reason for this is a missing filter section and that they were not created for the use in a studio. The lower sound resolution is also a reason for this problem. But we talk about problems and I like to solve them. Just take your old Casio or Yamaha toy keyboard and plug it into a filter, or any effect-section. The result is often a true surprise for many people, because most of them would think, that toy, which was made for children, can't have a great sound. And the fact, that they were made in this decade and had to withstand more stress, makes them really reliable and portable. What comes out of these little machines, is the same basic waveform, like from a great synthesizer model. And again, I have to note, that the resolution of the waveform is not the same. And especially this, is something, which is a part of their personality.
