# Shapey! Expanded: An Experimental "Wavetable" Synthesizer

Shapey! is an open source, experimental synthesiser with a unusal approach to wavetable synthesis. Its primary sound generator is a single "complex" wavetable oscillator with three sections. While it borrows terminology from FM synthesis, its architecture is quite different. The modulator controls the pitch and, to a certain extent, timing of a sample player (carrier), enabling several distinct synthesis techniques* , depending on their configuration.

This listing is for an upcoming, collection of additional sounds and presets that expands Shapey!'s sonic capabilities, and helps support its future development. It is yet to be finished. Purchase now to pre-order at a reduced rate.

Features:

• Complex wavetable oscillator
• Waveshaping & FX section
• Versatile sample player
• Dual filter
• Comprehensive modulation
• Arpeggiator/step sequencer
• VST3 and Audio unit plugins for Mac OS & Windows

The Oscillator

Modulator

In its first mode, the modulator functions as a simple multi-waveform oscillator with pitch, glide, and output gain controls. A sub-oscillator with phase and AM controls can be added to the signal. Additionally, the pitch can be quantized or synced to tempo, allowing it to act as an LFO. In its second mode, it replicates the entire oscillator section, placing a sample player after the oscillator, which enables the use of two samples within a single patch.

Transformer

The transformer sits between the modulator and carrier, providing various waveshaping, FX, and filtering options. It includes a mix control along with two additional controls whose functionality depends on the current mode.

Carrier

The carrier is a versatile sample player with controls for position, input gain, smoothing, quantization, and pitch shifting.

The Filter and "VCA"

The filter is a dual low-pass/high-pass design, similar to the Korg MS-20, capable of operating in serial or parallel. Additionally, the "modulator in" control allows the signal from the modulator to be routed directly into the filter, finally there is a simple AHDSR envelope at the end of the chain.

The Modulators

The modulation section includes an AHDSR envelope, a looping AR envelope with tempo-synced attack and release stages, a loopable table envelope, and two master LFOs with multiple wave shapes and quantization options.

The Arpeggiator

A flexible arpeggiator/step sequencer rounds out the feature set.

*In addition to good old fashioned, subtractive synthesis Shapey! can turn it's hand to AM, Waveshaping, some sort of FM, single cycle and scanning wavetable, crude loop playback and and even cruder pseudo time stretching.

Built with HISE & FAUST.

Please note that Shapey! is under active development, it is not a finished product and there will be bugs :).
