The Scapes Synthesizer incorporates the richness of pre and post envelope reverbs with wavetable and scanned synthesis. You’ll find yourself making mostly beautiful pads with this instrument.

There are two bandpass filters that help shape the sound which you can pan individually in the stereo field. Once again, a small modulation system is included on the right side, so that your pads and textures will always have motion.


Prkshn is a sound design tool that specializes in generating percussive envelopes and random rhythmic sequences. This is a single voice synthesizer in which there are four sound generation mode and seven unique envelopes. Each mode and envelope uses a different synthesis technique to generate it’s texture. Experiment with both the voice and envelope options individually by perusing the drop-down menus.

The Sync option turns on the sequencing function of this instrument. You must have Live playing for this to work – Prkshn uses your session’s tempo to sync up to your track. Select Cycle, next to the Sound and Envelope menus, to cycle through the options in ascending order. Select Rand to randomly select sound and envelopes.


Pitch Mod Delay is a delay processor that can manipulate the pitch of the delayed signal. It has features like stereo spread, low-pass filter cutoff, and a feedback control.

The Modulation section controls a LFO which is modulating a pitch factor on a phase-vocoded delay signal – this ensures that the delay time remains the same while the pitch is being manipulated. Pitch Offset is a factor which affects the pitch of every iteration of the delay tap.


This monophonic synth is a great tool for designing dirty bass sounds, harsh analog textures, and massive noise clusters. Mono-Classic consists of two oscillators, amplitude and filter envelopes, two bandpass filters, and a modulation matrix.

Everything is capable of automation and is MIDI mappable with Ableton Live. (Hint: Try Automating elements of the Modulation Matrix for powerful results)


BeatSketch is a four voice drum synthesizer. You have the power to design a Kick, Snare, Hat, and Tone voice – making up a minimalist drum set. The MIDI notes C3, D3, E3, and F3, are mapped to these drum voices respectively.

On the right, there is a randomization system, which uses a interpolated gaussian distribution as a modulation signal. Every element (except for volume and panning) of each of the voices is modulated by this signal when attenuated in. Experiment with attenuation amounts to get the most natural or unexpected sound.


XScanTable is a simple and efficient implementation of the Scanned Synthesis Algorithm by Verplank, Shaw and Mathews.

It uses the trajectory of a “circular string” and animates a collection of external tables for variety and richness.It is a simplified version of XQuadScanned particularly suitable for large string pads.


XQuadScanned uses a unique synthesis technique devised by Bill Verplank, Rob Shaw, and Max Mathews between 1998 and 1999 at Interval Research,Inc. They were working there on new ways of “animating” sound and how to directly control,in a complex and interesting way,the evolution of the timbre during live performance – a human/haptic rates.

The result was “Scanned Synthesis” in which wavetables are given “physical” characteristics by assigning to the elements in the table (the samples) physical parameters (mass and elasticity) and connecting them to each other in a network to each other and to the “ground” via “damping”.

You can read more about this powerful new synthesis and processing technique in The Csound Manual and from some of the online tutorials, but CsoundForLive is the best place to “explore” the sound world that this technique reveals – one in which dark, rich, timbres and textures are “constantly and naturally evolving”.

XQuadScanned follows four pre-defined trajectories around the network of masses which can be unique or identical and used simultaneously – for even more sonic depth.


A resonator is a device or system that exhibits resonance or naturally resonant behavior.It’s a filter, but one with “personality”, “physicality”, and “attitude”.

Based on Fran├žois Blanc’s “mode” opcode, the CsoundForLive resonator effect gives the user a wide range of physically
modeled percussion instruments to use are a controllable filter for their sources audio.

In the Csound Manual, John Bower has compiled a list of “modal frequencies” for various objects and materials such as tabla, wood, string, tibetan bowl to name but a few,and these were used as the basis for this collection.

This beautiful, unique, and rich “filter” adds interest and nuance to samples and synths and will surely become one of your go-to processors in all your Live work.


Built with Victor Lazzarini’s PVS opcodes, that allow for real-time “streaming” phase-vocoder based analysis-resynthesis, PsychoDelay creates a complex “cloud” of unique (multiple) delays in different frequency bands.

The pvsanal opcode is used to analyze the input and generate “fsig” data using phase-vocoder based overlap-add analysis.Using the pvsbuffer opcode, a second process reads from a circular buffer, of user specified length (in seconds),taking a handle for the buffer and a time pointer that holds the current read position (also in seconds) and wraps around when reaching the end.

Multiple instances of this process, with different time positions, are resynthesized using an inverse FFT producing this spectrally shimmering result.


Metallics is a 4-operator Phase-Modulation (PM) synth.In a way, PM is related to Frequency Modulation (FM), but the difference is that whereas in FM the frequency of the carrier is modulated to produce harmonic and inharmonic “sidebands”, in Phase Modulation, the sidebands are the result of modulating the Phase of the “carrier”.

Like Yamaha’s classic Tx81z 4-operator FM synthesizer, Metallics also features four “operators” that can use a variety of waveforms as their starting “spectrum” and thus produce much more dramatic, complex, and interesting resulting spectra.

These four operators can be configured into many unique modulator-carrier arrangements and each features an independent LFO,ADSR.These “algorithms” mix to a choice from a bank of complex classic filters and resonators which can be controlled and automated using an onscreen XY control or MIDI.

To round out the instrument, there is a multi-effects section featuring delay, chorus, phaser,flanger, and comb-resonator, plus an independent reverb too!

Many sections of the instrument feature “global-random” buttons that produce a wide range of complex textures and futuristic timbres. Infinitely rich. Infinitely beautiful.

Metallics is “heavy.”
