{"product_id":"36753","title":"Tiptop Audio Buchla Model 248t MARF Multiple Arbitrary Function Generator","description":"\n\u003cp\u003eThe \u003cstrong\u003eTiptop Audio Buchla 248t MARF (Multiple Arbitrary Function Generator)\u003c\/strong\u003e brings one of Buchla's most legendary control voltage tools into the modern Eurorack format. Originally released in the 1970s, the MARF earned a near-mythical reputation for its depth, flexibility, and forward-thinking design. This updated 248t version faithfully recreates the original concept while refining it for contemporary modular workflows.\u003c\/p\u003e\n\u003cp\u003eAt its core, the MARF is far more than a sequencer. While it offers \u003cstrong\u003e16 stages of programmable control voltages\u003c\/strong\u003e, each stage can be independently configured with unique behaviours, allowing it to function as a sequencer, envelope generator, portamento processor, or a highly complex modulation source. Stages can step discretely or smoothly interpolate between values, be quantised to 12 divisions, mapped to specific voltage ranges, and assigned individual timing characteristics.\u003c\/p\u003e\n\u003cp\u003eA defining feature of the MARF is its ability to \u003cstrong\u003egroup stages into programmable cycles\u003c\/strong\u003e, enabling the creation of evolving pitch sets, rhythmic structures, or multi-stage envelopes. Each stage can be assigned functions such as \u003cem\u003eStart\u003c\/em\u003e, \u003cem\u003eStop\u003c\/em\u003e, \u003cem\u003eSustain\u003c\/em\u003e, \u003cem\u003eFirst\u003c\/em\u003e, or \u003cem\u003eLast\u003c\/em\u003e, giving you precise control over how sequences and cycles behave. Stages can be addressed internally or via external CV and pulse inputs, opening the door to deeply interactive patching.\u003c\/p\u003e\n\u003cp\u003eDespite its 16-stage architecture, the MARF includes \u003cstrong\u003etwo independently addressable output sections\u003c\/strong\u003e, allowing simultaneous access to different stages for layered modulation and complex interactions. A dedicated \u003cstrong\u003eTime Multiplier\u003c\/strong\u003e (with CV control) scales timing globally from 0.5x to 4x, making it easy to stretch or compress modulation across a patch.\u003c\/p\u003e\n\u003cp\u003eAcross the top panel, the MARF provides a comprehensive set of outputs, including stored voltage, stage-based ramp reference, time-proportional voltage, and assignable pulse outputs. Integration with Tiptop's \u003cstrong\u003eART protocol\u003c\/strong\u003e enables seamless communication with compatible modules like the 259t, supporting precise tuning and expanded control possibilities, including polyphony.\u003c\/p\u003e\n\u003cp\u003eCombining vintage Buchla philosophy with modern reliability and integration, the 248t MARF remains one of the most powerful and flexible control voltage generators available in Eurorack.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHighly programmable control voltage
