The Professor’s Laboratory

Here are some of my electronic projects and some modifications to musical instruments and gadgets that we use in the band. If you’re handy with a soldering iron, you might like to try these yourself!

 

 

The Casio SK samplers were the  world’s first budget sampler, costing less than $100 back in 1986. The Lo-fi band scene has seen a resurgence in their use. I have developed some of these modifications for it to overcome some of the limitations in the original functions or features, so as to become more useful as an instrument in today’s music scene.

The loveable Casio EG-5 Cassette Guitar is a wonderful 80’s Casio gadget - a guitar with a cassette player and speaker built into it! It is, in fact, a very good guitar—built by the company that builds Ibanez guitars for them. It is in essence, a late 80’s Ibanez guitar - perhaps an RG series, and plays extremely well. It is no toy! I’ve done a few modifications to it to improve the electronics.

The MMT-8 was the quintessential 80’s sequencer—they were everywhere back then. The best sequencer ever built for live performance, you could do song remixes on the fly live by muting each instrument track on or off while playing, as well as a lot of really easy editing.

 

It’s main drawback was its small memory—realistically only about 10 songs could be stored in it before filling up the memory. I have developed a 16x memory expansion for it!

This RAM card was used in a number of Casio’s professional range of synths, notably the VZ-series synths and PG series guitar synths. They are quite rare and fetch over $100 on ebay.

 

Here, I propose to make them by modifying the more common and cheap RC100 ROM card.

The rare and highly sought after DM100 has a sampling keyboard as its upper keyboard, similar to an SK-8.

 

I have created a 16x sample memory expansion for it that increases the samples from 4 to 64 samples!
