Basic Sound Synthesis of DJs - Monophonic or Polyphonic

By Sandy Shaw

Even currently, nearly all synthesiser will give you the monophonic or polyphonic selection. Today though with new technology this has become a good deal stronger, yet cheaper to produce. Its got to the point where nearly all of the newer synthesiser can create an almost innumerable amount of notes all at the same time. Just like a piano will. Which is to say, monophonic synthesizer only plays 1 note at any 1 time. Its a useable setting because it forbids two keys from being hold down at the same time.

Which likewise implies they could most likely over lap one another. The monophonic is great for numerous of the lead and bass sounds too. For two or more notes to play at the same time you require the polyphonic.

To be able to slide between 2 notes the synthesiser needs the Portamento/guide. You will get your greatest effects of producing a bending 'tween notes if you utilize the portamento on monophonic sounds. On the other hand it could likewise be practiced polyphonically if played in the block chords style. You could go from a really slow sweep between 2 notes to a elementary glide. This would allow a difference in the severity of bending. This's finished when you change the time and some times the scale of the glide. It's genuinely 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 utilise two oscillators, with one being the master and the other one slave you're producing the effect of hard sync (oscillator sync). In this case, the slave oscillator operates faster or slower than the master, whereas the master runs as standard with its waveform. If you trigger the two oscillators at the same time, you will get truly weird harmonic effects. The slave will also start to perform once again via its wave form. It wont matter whether it complete it's cycle. This occurs when the master oscillator is put into action.

Take two oscillator inputs and multiply them against each other. This's dependent on the frequencies. This's recognized as ring modulation in music synthesis. This's the perfect result for creating dissonant, percussive sounds, due to the non harmonic result - 18780
