Kurkesmurfer

VCV Rack 2 instrument family

SpaceTime

One programmable field of stages. Up to eight independent ways through it.

Architecture

An instrument assembled to fit the patch.

SpaceTime deconstructs the programming surface and function generators of the Buchla 248 concept into a contiguous VCV family. Stage blocks own their data, heads share the field without sharing transport, and MIDI sits transparently between them.

Head All (optional)→Head ×1–8→MIDI→Program→Stage4 ×1–16

Preview builds

Install SpaceTime manually.

Download the `.vcvplugin` package for Apple Silicon macOS, Intel macOS, Windows x64, or Linux x64 from GitHub Releases.

  1. In Rack, choose Help > Open user folder, then quit Rack.

Lineage

A behavioural reinterpretation.

SpaceTime is inspired by the Buchla Model 248 MARF and Tiptop Audio/Buchla 248t. Its code, panel artwork, MIDI system, extended playhead modes, and virtual bridge are original work. It is not affiliated with or endorsed by Buchla USA or Tiptop Audio.
