Casio Collectors

I'm REALLY looking forward to seeing what you can do with this!  I love the idea of modifying keyboards in a useful way, rather than just circuit bending (which, to my ears, just produces noise).  

If you ever decide to figure out how to expand the flash memory on the WK3*00 synths, I'll be ecstatic!  My WK3200 has 100 slots for user waveforms, but it can, realistically, only hold about 7 (or so) useful sounds until it fills up the flash memory (which has only about 3.5 Mbs of useable space).

I'm going to install one on each of the upper and lower keyboards; each keyboard will have the ability to be a MIDI sound module via MIDI IN, as well as a be a controller keyboard via MIDI out, on separate MIDI channels. Or, I can control the top keyboard witn the bottom keyboard etc. I will have a MIDI patch switch selector that will enable me to configure different arrangements such as these.

It contains only one large board. The presets for the upper board are the same as an sk8, and it has 4 sample slots, as the sk8 does. The board has the same RAM chip as the SK8. That is where the similarity ends. It has no SK type drum sounds. There is an area on the board that contains some of the chips from an SK8, and another for the lower keyboard, which has the same sound set as the MT240, but all built on to the single board, so there is no similarity for the address lines and tracks in comparison to the SK and MT. It is its own beast.

Today, I'm going to remove the sample RAM chip and put a socket in its place, to mount a much larger RAM chip, capable of giving it 16 times the sample capacity of the original chip - so instead of 4 samples, it will have 64 samples, in 16 selectable banks!!

Basically a Casio SK8 sampler on the upper keyboard (8 preset tones, 4 sample memories) and an MT540 or MT240 on the bottom. Remarkably compact and light. There's some pics of it in the Photos section here.
