Sound Synthesis of DJs - Music Monophonic or Polyphonic

By Sandy Shaw

Even presently, most synthesiser would give you the monophonic or polyphonic choice. Today though with new technology this has become much stronger, yet cheaper to make. It's got to the point where nearly all of the newer synthesiser could produce an almost innumerable amount of notes all at the same time. Just like a piano will. Which is to say, monophonic synthesizer simply plays one note at any one time. It is a usable setting because it prevents 2 keys from being hold down at the same time.

Which likewise implies they can most likely over-lap each other. The monophonic is great for some of the lead and bass sounds as well. For two or more notes to play simultaneously you require the polyphonic.

To be able to glide between two notes the synthesizer needs the Portamento/guide. You'll get your best effects of creating a bending 'tween notes if you utilize the portamento on monophonic sounds. On the another hand it could also be applied polyphonically if played in the block chords style. You can go from a truly slow sweep 'tween two notes to a uncomplicated glide. This will permit a difference in the severity of bending. This's finished when you change the time and at times the scale of the glide. Its very usable for SFX.

In subtractive synthesis, you could utilize the primary ideas of frequency modulation, which's an entire entity of synthesis. You would be practicing it's sound creation methods. If youre to speed up LFO, you will be able to create FM effects. The rate is set at such a high speed an audible pitch is produced by the oscillator.

A very sharp piercing effect is reached when a non-harmonic sound is created by applying the 1st oscillator to modulate the pitch of a 2nd oscillator. It has been found that FM effects could not be used successfully on analogue synthesizer keyboards.

If you use two oscillators, with one being the master and the other one slave you're producing the effect of hard sync (oscillator sync). In this instance, the slave oscillator runs faster or slower than the master, whereas the master works as normal with it's wave form. If you trigger the two oscillators at the same time, you'll get very peculiar harmonic effects. The slave would also start to perform over again via its wave form. It wont matter whether it complete its cycle. This happens when the master oscillator is put into action.

Take 2 oscillator in-puts and multiply them against each other. This is dependent on the frequencies. This is also known as ring modulation in music synthesis. This's the perfect result for creating dissonant, percussive sounds, due to the non-harmonic result - 18423
