Basic Sound Synthesis of DJs - 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 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 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 truly sharp piercing effect is reached when a non harmonic sound is created by utilising the beginning oscillator to modulate the pitch of a second oscillator. It has been found that FM effects could not be utilized successfully on analogue synthesizer key-boards.

If you utilise two oscillators, with one being the master and the other one slave youre producing the effect of hard synchronization (oscillator sync). In this instance, the slave oscillator runs faster or slower than the master, whereas the master operates as standard with its waveform. If you trigger the 2 oscillators at the same time, you will get very unique harmonic effects. The slave would also start to perform once again via it's wave form. It wont matter whether it complete it's cycle. This happens when the master oscillator is put into action.

Take two oscillator in-puts and multiply them against one another. This's dependant on the frequencies. This is acknowledged as ring modulation in music synthesis. This is the perfect answer for creating dissonant, percussive sounds, due to the non harmonic result
