How to use VCV Rack Explanation of Surge for Rack

This is yosi from Chillout with Beats.

When I was looking for a new module with VCV Rack, I found a familiar name.

Surge, who wrote an article in the introduction of free soft synths before, seems to be able to run Surge on a module-by-module basis with VCV Rack.

I tried immediately.

It was divided into 18 pieces.

So, this time I will only give an overview.

However, the manual only roughly explains everything except the oscillator.

Overview of each module of Surge for Rack

Basically, it is translated by Google as usual. (I'm lightly fixing it)

Surge for Rack Oscillator Modules

Surge has two rack modules, the "SurgeOSC" module, which produces waveforms, and the "SurgeWTOSC" module, which is a wavetable oscillator on top of a set of wavetables.

SurgeOSC

The SurgeOSC has five waveform generators that you can select with the toggle button at the top.The bass pitch is set by note or frequency (switching "f / n"), modulated by a polyphonic CV, and has a collection of parameters. As described in the Surge manual, the types and meanings of the parameters vary from oscillator to oscillator.

Unison count is a special property that ignores the control voltage input for technical reasons.

SurgeWTOSC

SurgeWTOSC is a surge interpolation type wavetable oscillator. There are two interpolation modes.They are WaveTable mode, which simulates an early D / A converter that outputs preset waveforms, and Window mode, which uses a collection of more common interpolation methods.It also ships with over 2 wavetables.

The main WTOSC control that OSC lacks is wavetable selection.Wavetables in the waves are divided into categories that can be switched by the “cat” spinner, and each category has a collection of wavetables selected by the “wt” spinner.Browsing the wavetable does not change the oscillator.When you are ready to load the wavetable, press the "Load" button. A red light with the "Load" button lit indicates that you are looking at a different wavetable than the one you are playing with.

If you have created custom .wt files in ~ / Documents / Surge (or in the appropriate location of your OS according to the Surge documentation), the SurgeWTOSC module will make them available.

Surge for Rack The SurgePatch Player Module

SurgePatchPlayer plays surge patches with a full-fledged surge synthesizer installed.The notes played are triggered by a polyphonic gate input (which acts as a note-on-note-off trigger) and capture the triggered note and velocity using 1v / oct notes.Other control surge reads from standard MIDI are exposed as CVs.

Follows the same load / browse semantics as SurgeWTOSC.

Surge for Rack FX Modules

The FX module will eventually have a custom faceplate for each FX.For now, they can be divided into two groups, those with a custom faceplate like the chorus shown here.

Module with custom faceplate in FX

Surge Chorus

4-stage chorus algorithm

Surge EQ

The EQ unit provides 3-band full parametric equalizing.This high quality algorithm has a much better response at higher frequencies than a digital equalizer would normally have.

Surge Rotary

Rotary speaker simulator algorithm

Surge Freq Shift

Frequency shifter effect Provides a delay unit and a feedback loop to provide a continuously shifting repeat delay.

SurgeVOC

The Surge voice input is used to modulate the carrier signal at the input stage of this 20-band vocoder algorithm.The carrier channel is stereo, but the modulator uses the monaural sum of the input channels.

Module without custom faceplate in FX

Like the stereo delay shown here, with a generic faceplate whose parameters are shown as a simple labeled list.

Surge Delay

Surge's delay algorithm is very versatile and works well as both an echo / delay and a chorus.

Surge Phase

4 stage phaser

Surge Distort

Distortion Algorithm Provides many EQ options as well as a feedback loop for changing the tone of the clipping stage.

Surge Reverb

The reverberation algorithm is suitable for simulating room acoustics, adding atmosphere to the sound, and creating special effects.

Surge Conditioner

The conditioner is a simple EQ, stereo image control, and a limiter built into one unit.The limiter automatically applies make-up gain.

Surge for Rack Filter Modules

Surge has an extensive collection of interlocking filters and filter banks. As of 1.beta1.0, only the most primitive single bike wad unit is available as a SurgeBiQuad unit.It supports multiple filter types.

Surge for Rack Other modules

SurgeLFO

Surge LFOs are polyphonic LFOs. There are two modes.If ungated, it will output a single free-running LFO controlled by the top section of the control panel.If gated (monaural or polyphonic), it will output a collection of enveloped LFOs according to the DAHDSR envelope shown in the section below.When gated, there is one unique LFO and envelope for each gate polyphony.All items can support tempo synchronization to the clock.

Surge ADSR

Surge ADSR is a polyphonic ADSR envelope generator with multiple modes and tempo synchronization.Polyphony is driven by the gate input.

Surge Wave Shaper

Surge Wave Shaper is a collection of waveform shaping algorithms for adding warmth and distortion to an input signal. Surge Noise is a noise generator that appears in VST's Surge Mixer.

Surge Clock

SurgeClock is a small utility clock that outputs the gate and CV at a specific BPM set by the control.

Surge for Rack Summary

I was surprised at all the modules that can be used.Perhaps open source itself was originally designed for each part (module).

Wavetable oscillators, filters and vocoders look pretty good.

Patch pliers are honestly a foul.

Modules whose GUI is still halfway will be updated, so update at the right timing.
