Sculpt A Sound that’s Uniquely Yours – Oscillators & Filters!

Oscillators are the basis of sound generation in subtractive synthesis. “Discovery Pro Synth” includes two primary oscillators, each with various modes and waveform types.

Waveforms available in “Discovery Pro” are:

Sine – FM, Leads, Percussion, Organs.

– FM, Leads, Percussion, Organs. Triangle – FM, Smooth Sounds, Bass, Flutes.

– FM, Smooth Sounds, Bass, Flutes. Square – Smooth Basses, Leads, Synced Waves.

– Smooth Basses, Leads, Synced Waves. Parabolic – Smooth Sounds, Pads.

– Smooth Sounds, Pads. Noise – Ambient FX, Percussion.

– Ambient FX, Percussion. Saw – Rough Bass, Edgy Leads.

– Rough Bass, Edgy Leads. Pulse – Vintage Synths, Pads.

Oscillator 1 (OSC1)

OSC1 is the primary sound source in “Discovery Pro”. This oscillator uses the pitch of the incoming note and plays it in the specifed waveform type.

OSC1 can be any one of the following waveform types – Sine, Triangle, Saw tooth, Parabolic (Saw tooth with red led), PWM (Pulse Width Mod), Square.

Oscillator 2 (OSC2)

“Discovery Pro” offers a second oscillator, which adds additional sound design capabilities to your patches. It may be used in various ways such as mixing with, or modulating the frequency of OSC1.

OSC2 can be set to any of the following waveforms – Triangle, Saw, Parabolic (when Saw led is red), PWM (Pulse), White Noise, Pink Noise (Noise with red led), Square.

Wave Oscillator (WAVE)

There is also a third oscillator, which adds dramatic sound design capabilities to your patches through the use of WAV/Soundfont files. You can even add your own sounds!

Sound banks and waves can be selected by clicking < and > control or clicking at the LED area to display a drop-down menu.

To add your own sound banks just zip a set of WAV fles and use .dwb extension, or select a SoundFont 2 (SF2) file. Then place it in Documents > discoDSP > Discovery Pro > Waves folder and they will appear next time Bank LCD is clicked.

Filter Section

Once oscillators are mixed, sound is next routed through the Discovery filter section. This section will transform the frequency response of the signal.

A filter is a unit that changes the magnitude of a range of frequencies of the sound, boosting or cutting these frequency values.

The two most common filter parameters are the Frequency and Resonance controls.

Frequency or ‘cut off’ point – This value sets the frequency point affected by the filter response.

– This value sets the frequency point affected by the filter response. Resonance – This value determines the amount of amplifcation of the range of frequencies surrounding the frequency (cutoff) point.

“Discovery Pro” has 12 fliter types including a selection of Lowpass, Bandpass and authentic Moog modelled filters! Additional available controls include ADSR, Keytrack, and Distortion.

Zero Delay Nord Lead 2 and 12dB / 24dB Moog® filters

Discovery Pro 6 also includes brand new Nord Lead 2 modeled Zero Delay Feedback filters. One listen and these will blow your mind… they sound amazingly great!

There are also Moog filters called X and Y, bringing a more sophisticated tone in addition to the 8 previous Discovery filters.
