Vocoding a Drum Machine

Using Cubase's vocoder to modulate my Juno-G's internal drum machine onto the TX802. I used a handy little plug-in called Elottronix to keep the loop going.


I like this effect, it's an unusual way of slicing a synth. Depending on the drum loop used, and the drum samples played you can achieve many different effects and sounds.

I'll post the instructions for how to set up the vocoder and the loop in Cubase next week. It's very simple, but the instructions in the video are a bit vague.

Yamaha VSS-200

Let me start by taking you back, way back, to the beginning of my synthesizing career. As a child I was given a Yamaha VSS-200 sampling keyboard - one of the fantastic but basic PortaSound range. I loved it, it was new and exciting. The onboard sounds are generated using FM synthesis, the same method used by the Yamaha DX7 and it's successors, although this little synth sounds nothing like it's big brothers. It lacks any form of FM programming, the patches are badly written and there's not even a sniff of MIDI.
I didn't care about realism though, I wanted weird sound effects and harsh buzzing sounds. I didn't care that the keys were the size of matchsticks, or that the internal speakers were tinny and harsh. What impressed me the most about this tiny little thing was that if you pressed a little red button near the top, you could record a snippet of sound using the attached microphone. You could then apply a whole host of effects to it and play it back using the keyboard. The overwrite function was useful too, I spent hours as a child making formula 1 noises into the mic and creating layers of sound. Ah happy days...

Sadly, while moving back from South Africa to the UK, my beloved VSS was broken. I was gutted, nothing could replace it. The sampling feature alone seemed to be unique to it (not a single one of the Yamaha keyboards I came across while looking for a replacement had the feature, and the Casio SK1 was unknown to me).

Years later I was online and I stumbled across a familiar looking keyboard. Someone had circuit-bent a VSS-200 and were selling it on ebay for £70. I was ecstatic, i finally knew what i was looking for. Every so often I checked eBay but nothing came up. Eventually I found an advert in a local newspaper for one and responded quickly. My second VSS wasn't in great nick, the speakers didn't work, there was a broken key and some of the buttons didn't work. After a bit of cleaning and soldering though, it emerged almost as good as new.

About a week later I was trawling eBay and I found another VSS, also not working. I bought it, and upon getting it home I discovered that all it needed was to have the speakers re-soldered to the main board. This one was in even better condition. The keys were whiter and intact, the speakers sounded fresher, the buttons didn't stick and the microphone sounded less fuzzy.

I have them both, and I have gigged with them both at one time or another, just to prove they were up to it I suppose. One of them became somewhat well known when I sampled my lecturer's voice and played tunes with it.


So there you have it! While it's not the most technically advanced synthesizer/sampler out there (1.9 seconds of 8-bit audio is hardly luxury), the VSS-200 will always be special to me. It's the keyboard I first began to learn on, and it's unique sampling capabilities even have their uses today, 21 years after it was first released.


Just a quick note, I wrote the VSS-200's Wikipedia article, which can be found HERE

Let me introduce myself...

Hello keyboard fans!

My name is Matthew Harrison, I'm (currently) 19, living and studying in Durham, England. I'm a massive fan of progressive rock, and everything to do with keyboards. I've grown up with three passions; technology, old stuff and music. I'm a big computer geek, I love fiddling on and seeing what I can make my machines do next. As a child I took things to pieces to see how they worked, and build new things from things that didn't work. I love old technology too, I have a big record collection, and plenty of gadgets from the past lying around my flat. Some of these things happen to be keyboards, or things relating to them.

When I was a child, I heard Pink Floyd's masterpiece "Wish You Were Here". I vividly remember hearing the opening passage of "Shine On You Crazy Diamond" and thinking to myself "I want to make those noises". The drone of the ARP string ensemble was mesmerising, completely different from anything else I'd ever heard before. Not long after I was presented with a toy keyboard, and then a Yamaha VSS-200. Before long I'd taught myself how to play some simple songs, and was picking up snippets of tunes by ear.

Since then my tastes have expanded beyond Pink Floyd, and the technology I have access to has increased in complexity. I don't have my original VSS-200, but I have two others, as well as a Roland Juno-G, a Yamaha TX-802 tone generator and a Roland F-100 digital piano, not to mention the stacks of VSTs and samples I have access to. This blog will cover what I have been able to do with those instruments and software, as well as talking about the music and musicians who have inspired me, keyboardists or otherwise. It's basically a palce for me to ramble on about my somewhat geeky hobby, and if anyone happens to read it then so much the better!

I aim to be posting twice a month. Sometimes it'll be more, sometimes it'll be less. I have a few things lined up for the future though, so there should be plenty of activity.
