Hundekraft expands the original Teenage Engineering OP-1 with selectable synth engines, drum synthesis, effects, sequencers and performance tools. Its browser workshop builds a personalised firmware from your unmodified R246 update file, then supplies a preset pack matched to the selected features. Sounds range from wavetable, granular and chip synthesis to thumb-piano tones and a virtual analog polysynth, with stutter, modulation and spacious reverb effects. The firmware supports 300 user synth presets. Chord mode, an editable C64-style arpeggiator and a four-track MIDI recorder add ways to develop patterns and automate sound controls. Four independent tapes, undo, loop editing and expanded sampler tools support arranging and recording. After the first installation through the OP-1 boot menu, the workshop can manage plugins and send reviewed updates over USB MIDI. This firmware supports the original OP-1 only; it does not run on the OP-1 Field.
