Sample Pack: Merlin Electronic Game

Photo courtesy: the internets.

While searching the local re-use centre for electronic goodies a couple of weeks ago I spotted a cool retro-looking box with a hand-held game on the cover. In wonderful space-age chrome lettering on the side was the word 'Merlin.' "6 electronic games," the box proclaimed,  "vocabulary of space age sounds," "powerful computer brain." The game itself still resided inside, and though a little battered, it looked to be in working order. So for the princely sum of 25 cents it was mine.


I knew of this game, but had never played it. It was made by Parker Bros. in 1978 (a year before I was born). It's actually quite fun, but more importantly it makes some wonderfully retro bleep sounds. I've created a sample pack containing all these sounds, recorded direct from the speaker using my CAD GXL1200 through an ART USB preamp. The pack is hosted on freesound.org and is 100% royalty free.

One further note: although I made sure to use fresh batteries when making the recording, I realised afterward that Merlin is out-of-tune by approximately three semitones. Thus the tone 'do,' which should be a C, is closer to an A. This being the digital age, it can easily be corrected if you plan on using the sounds musically.

The Saga of the Typewriter

Introduced in the first episode of Tales of Elves and Trolls is a contraption called a 'type-writter.' In essence, it's a typewriter to the Nth degree: a steam-powered lump of metal, pistons, cogs, and keys. In order to create the sound of this beast, I set out to find a typewriter to record in-studio. This was easier said than done!

I've frequented thrift shops, flea markets, and garage sales for years. A lot of the electronic toys that I turned into circuit-bent instruments have been sourced from them. And, yes, I've seen my share of typewriters in them too. But when it came to actually needing one, none were to be found. I came close: I found a monstrosity of a thing at the Re-Use Centre, which looked like it came from a WW2 army hospital. Unfortunately, it didn't sound as big as it looked, so it remained hidden away on its dusty shelf.

Months passed. I located no less than two electric typewriters, and had a local antiques dealer keeping an eye out for a mechanical one. It was time for plan B. I sent my aunt an e-mail. She teaches at the local college, so I figured if anyone could find me a typewriter it would be her. Lo and behold, a few weeks later I was loaned this 1925 Remington 12:


It weighs as much as a small planet, but fulfills all the requirements and is blessed with a wealth of character. Just gazing upon it is a treat. I gave it a rudimentary clean and set about working out what sort of microphone configuration would best capture its sound.

After a little experimentation, I settled on placing my contact mic beneath it (it's open at the bottom) and suspending the CAD GXL1200 above it on a gooseneck stand. The typewriter produces an incredible amount of vibration despite its weight, so the stand had to be placed on a separate surface to the one supporting the typewriter to avoid unwanted 'mic stand wobble' noise. There wasn't much choice with the contact mic (which in this case is acting as a pickup rather than being attached to the surface of the sound source), so a towel was placed underneath.


As with my breeze block experiment some weeks ago, I recorded using both mics at once, on separate channels. My plan is to mix both recordings together after I've edited and pitch-shifted them. There's a surprising amount of variation in the sound of each keypress, so I recorded the entire sequence I need for my production (two takes) as well as additional sounds such as carriage return, bell, paper-winding, etc...

My only worry at this point is the length of the recordings. Not counting the extras, they add up to several minutes. The scene in the story should realistically be under a minute. I have a feeling I'll need to speed the typing up or edit keypresses closer together or ... something. Oh, the joys of real life vs. fiction! At any rate, there's a lot of other work to be done on these recordings before I reach that stage. The GXL1200 source will need compression, to bring out the nuances lost to the low headroom of digital recording, and the contact mic source will need noise reduction and possibly EQ. I'll explain that process in more detail in 'Field Recordings Part 2,' whenever I get around to posting it.

You may be wondering why I've gone to so much trouble when I could just as easily have used a couple of generic typewriter sounds from a sound effects collection. Well, for one it's a lot of fun, and as I mentioned before: each keypress has a unique sound depending on which bit of the antique mechanics it activates, and how hard you press it. There are also subtleties such as parts of the typewriter vibrating from the sheer momentum behind the tension of the carriage. All these things, I hope, add up to a unique and expressive 'performance' rather than a stale computer-generated facsimile (not that there's anything wrong with the latter).

New Equipment

In anticipation of the soundtrack work and the sound effects I'll be doing, I've picked up some new bits and pieces for the studio:


CAD GXL1200 pencil-style condenser mic. I already had a vocal mic by CAD, the GXL2200, but it's an upright mic and not very practical for positioning in front of instruments or devices. This one is tailored for instruments and acoustic sounds. I bought a gooseneck for it as well, so it can be positioned with some degree of precision.


ElectroHarmonix Small Stone Phaser (Nano). I've wanted one of these for ages, and finally found an excuse to buy one. This is the Nano version, which is technically the same as the vintage model only smaller. It has a unique sound and was famously used by Jean Michel Jarre on his 1976 album 'Oxygene,' to process synthesized strings and rhythm boxes, among other things. I have pretty much the same use in mind.


Danelectro Spring King. I have something of a fascination with the sound of springs. I even went so far as to build my own spring reverb out of a small slinky and a poster tube once, but it didn't work very well without amplified input and I never got around to building an amp for it. So, I bought this instead. It has its own built-in amp circuit, some real springs, and a digital delay circuit inside: all to emulate spring reverbs found in vintage guitar amps (and, as a friend of mine reminded me, found in the ARP-2600 synthesizer). I doubt very much if a guitar will be going anywhere near this. It will mostly be used with my synths, keyboards, drum machines, and circuit-bent devices.
