Dual Timbre v1.1 is an open-source printed circuit board by StudioKAT, from the StudioKAT/DualTimbre repository on GitHub. It is a 2-layer board of 132.2 × 128.5 mm with 149 parts on 91 nets, routed with 700 tracks and 176 vias.
It is built around the CJ431, B10K and 1N4148WS, with the 1N5819WS among its other parts. Its parts include 72 resistors, 28 capacitors, 13 connectors, 7 ICs and 6 diodes.
Dual Timbre は、Buchlaのウェーブフォルダー回路を現代的にアレンジした、デュアル構成のサウンドシェイピングツールです。
VCAのレスポンスカーブは、リニアからエクスポネンシャルまで連続的に調整可能です。
TIMBREおよびOFFSETノブは、パッチケーブルが接続されていない場合にはVCAの開き具合を調整するコントロールとして機能し、CV信号が接続されている場合にはアッテネーターとして動作します。
CV入力は0～+10V、オーディオ入力は±5V（10Vpp）を想定しています。
Dual Timbre is a dual-channel sound shaping tool that offers a modern take on the Buchla wavefolder circuit.
The VCA response curve is continuously adjustable from linear to exponential.
The TIMBRE and OFFSET knobs act as controls for the VCA's opening amount when no patch cable is connected, and serve as attenuators when a CV signal is present.
The CV input expects a 0 to +10V signal, while the audio input is designed for ±5V (10V peak-to-peak).

It measures 132.2 × 128.5 mm and has 2 copper layers, 1.6 mm thick.
149 parts, built around the CJ431, B10K, 1N4148WS and 1N5819WS. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the StudioKAT/DualTimbre repository on GitHub, at the commit this page was made from: the board is v1.1/KiCAD/Dual Timbre_v1.1/Dual Timbre_v1.1.kicad_pcb and its schematic v1.0/KiCAD/Dual Timbre_v1.0/Dual Timbre_v1.0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask StudioKAT before reusing the design.
