The Incredible Buchla Model 248, Reborn It’s hard to overstate how ahead of its time the Buchla 248 Multiple Arbitrary Function Generator (MARF) was when it was released in the ‘70s — in fact, the original unit continues to turn heads even today. Tiptop Audio and Buchla have partnered to bring you a modern, modular re-creation of this remarkably versatile control voltage generator in a sleek 72HP form factor: the 248t. Its 16 stages are programmable as fully continuous, quantized in divisions of 12, mapped to specific voltage ranges, or designated to a specific time interval, with each stage configured independently. The 248t MARF can act as your sequencer, portamento pitch processor, ADSR envelope generator, and so much more.
