## Implemented Interfaces

GstBtSidSyn implements GstPreset, GstBtTempo, GstChildProxy, GstBtChildBin and GstBtPropertyMeta.

## Description

A synthesizer based on the RSID emulation library of the C64 sound chip. The element provides a sound generator with 3 voices. It implements a couple of effects (see GstBtSidSynEffect), which are well known from trackers such as pitch slides, arpeggio and vibrato.
