Buchla Model 258t Dual Oscillator Comparator which makes the VCAs close

which makes the VCAs close instead of open in response to positive CV

which outputs both Fold and Pulse waveforms

modulars and modulation signals

That way it's possible to adjust the depth and polarity of the external control voltage which affects the parameter in question

including multiple sequencer directions

Buchla Model 258t Dual Oscillator Comparator which makes the VCAs closeWelcome to the Buchla & Tiptop Audio 200 series project. In this project Buchla has teamed up with Tiptop Audio to resume the production of Don Buchlas 200 series and convert it to Eurorack standards. These extremely rare pieces of equipment made almost half a century ago will once again be available, and this time to a wide audience. The Buchla 258t Dual Oscillator consists of two independent voltage controlled oscillators. Each has one processing
