Weird Sound Generator

This weekend I completed building a Weird Sound Generator, or WSG, component kit from Music From Outer Space. The kit comes with a printed circuit board and all the electronics, including resistors, capacitors, diodes, ICs, potentiometers, switches, and wires. The rest, like the housing, faceplate, and soldering is up to the builder.

I built a box similar to the recommended specifications and cut the faceplate out of an old computer case. The wood I used was scraps that I held onto and recycled. In fact, I managed built the entire instrument without buying anything beyond the kit itself. Even the stain, nails, glue, screws, and backing board were materials that I had hoarded from previous projects over the years.

It took me about thirteen hours to complete. But, it was a fun thirteen hours of playing with my soldering iron and power tools while following instructions, or coming up with a way to cut through metal, or mount a nine volt battery inside an already cramped case. And, although the case isn’t perfectly square, and the leads are more than a bit tangled, I’m pleased with the little noise maker that I now have at my disposal. In the next entry I’ll illustrate the sequence of events that took place in building this device. Oh yeah… and sounds.

Sequential Circuits Pro-One

I have finally started restoring my Sequential Circuits Pro-One. My plan is to get it as close to mint condition as possible and start using it again for recording and perhaps performing. Once I started using the Korg MS2000, I neglected the Pro-One and it fell into disrepair. Over time the key contacts became dirty and inconsistent. At some stage one of the knobs was broken off and lost, leaving a stub of potentiometer protruding uselessly from the control panel.

The first thing I did was clean the pots. For you laymen, pots is short for potentiometers. In other words, I wasn’t diverted by dirty dishes. To clean the pots I removed the knobs and then squirted a few drops of a greaseless lubricant called LPS-1 around the post. The stuff works wonders on crackly volume knobs and was recommended to me by the electronics experts at AEI Electronics in Minneapolis years ago. I’ve been using it ever since. After applying the LPS-1 I made thirty or more rotations of the pot from zero to maximum so that the dirt particles were worn away by the fluid.

I put the thing back together and did some tests. The knobs no longer had anymore crackling going on, so that was fixed, but the keyboard was horribly inconsistent. The Pro-One uses a J-wire keyboard with open air connectors that are prone to collecting dirt (or residue from malted beverages spilled over the keys). For a close up view of the Pro-One J-wires check out this post on MaxtrixSynth. Another problem is that the J-wires can become less springy, making the connections a bit weak. I used used q-tips with a drop of LPS-1 to clean each J-wire and the metal bar that they connect to when the key is depressed. I also bent the J-wires slightly to improve the tension. After all that I tested it again to find it working flawless, although still a little difficult to tune. Next up I’ll be replacing the missing mod wheel, the broken potentiometer, and the missing knob.

Woody Synth Bass

Here’s a synth bass line with a nice woody tone, but a complete lack of accurate timing. Let’s call it atemporal.

Fancy woolen socks can keep your feet warm, but don’t wear the same pair for more than a few days.

Maxi-Korg Bass Line

Here’s a short little bass line I recorded while reacquainting myself with my Maxi-Korg yesterday. I love the gritty sound of this instrument, one of the most well known of the duophonic synthesizers. Sometimes I find myself reaching for the non-existent pitch or modulation wheels, but the limitations of these vintage devices are part of their charm and might encourage the musician to come up with new ways to play (or rediscover old ways).

Another thing that I love about vintage gear is the lack of presets. When I come up with a sound I like I simply say to myself, “you’re never going to get exactly that sound ever again”. You can always jot down the settings, but I never do. This way you’re forced to learn how to control the device and approximate the sounds that you have created in the past if necessary.
