So you thought tuning your synth was a thing of the past? Indeed, how wonderful it is just to be able to switch on and play without having to check your tuning every time you want to do a bit of recording or present your musical wares to the public. Poor old guitar players still have to do it, but those clever tuning checkers are a real help and should be made compulsory for all string pluckers (and sampler owners for that matter - perhaps Ill tell you about their sampling applications some time). The problem with analogue circuitry is that it is inherently unstable. Take a common or garden transistor for instance. Its output current is dependent on the input current and guess what? Temperature. The transistor, which is the building block of virtually all analogue circuitry, is affected by temperature to a high degree (I couldnt resist that one). So, even with all manner of compensating techniques, any transistor based circuitry is bound to be prone to the effects of temperature changes, and oscillators, which ideally should be accurate to at least one part in a thousand, are first up for producing noticeable problems.
Now you might suspect that tuning an analogue synth is as easy, with the aid of a stable pitch reference or a tuning checker, as tuning any other instrument. Not quite, because not only do you have to check the tuning, you also have to make sure that the scale is correct. If the scale was incorrect, then you would find that one note would be in tune but the rest would be out, which is easily checked by playing the note an octave above. So the first thing you have to know about any Minimoog is that these things need to be checked and adjusted if necessary, otherwise you might lay down a track that is impossible to overdub to in tune, even by retuning or using varispeed. Hopefully, the scale tuning of the Minimoog that you find yourself sitting at will be very close to perfect, but if it isnt then you have a job on your hands. Since this is far from being a current instrument I think it would be a public service to describe how to perform the tuning procedure so that those Minimoogs that have drifted beyond usability may be fully rejuvenated. Full details in a separate panel.
Can you imagine a synthesiser that you have to reset totally each time you want to use a different sound. And to make presets you must have a wad of blank charts showing the front panel controls for you to write in your settings? Did anybody ever get round to producing any useful music with synthesisers in the old days? Well things were very different then, and peoples expectations were lower. You didnt expect to be able to buy a voice card with a hundred new and excitingly different sounds pre-programmed and ready for you to use. You had to start off each time with a basic idea of the sound you wanted and sufficient understanding of the instrument to be able to get from square one to that elusive perfect bass, or whatever. Lets take a trip around the instrument and see what we can get out of it.
Figure 1 is a classic Moog bass setting and if you hear it you will find that it is indeed fuller and richer than modern digitised equivalents. Is it better than a sample of an original Moog sound? Too right it is because you have full hands-on control of the sound at all times, and the Minimoog itself can modulate a sound as you play in ways your sampler cannot. And from this starting point it is just so easy to fine tune the sound to exactly what you want to hear that you cant help but wonder how on earth we ever let manufacturers deprive us of those oh so wonderful things called knobs. Figure 1 will serve as an aid for me to describe how the Moog does its stuff, and will also act as a starting point to move onto some other fine Moog features. I hope you have a Moog in front of you now because youre in for an adventure.Come on the FREE COURSE TOUR
