ALM Busy Circuits SID GUTS Deluxe

The ALM Busy Circuits SID GUTS Deluxe improves on its predecessor—which re-appropriated the SID chip into the modular realm—by offering extensive manual and voltage control options. Compared to the original, the module now features improved frequency control, a chord mode that uses all of the available oscillators to form a 1-3 voice chord, and a bunch of other sonic possibilities.

SID GUTS Deluxe Features

• 1 Volt per octave control of a ‘core’ SID oscillator 0-5v input (with tunable offset,) now with improved V/Oct tracking, adjustment and stability.
• Voltage controlled chord mode with inversion and up to 3 voice chords.
• Direct and voltage control of oscillator wave shape selection (Pulse, Triangle, Square, Saw)
• Filter switchable between 4 modes - 12dB/Octave HP , LP , BP & Notch (HP+LP)
• Voltage control of filter type selection.
• Wider frequency control range (full 8 octaves) with fine and course offset knobs.
• Attenuverters on both PWM and Filter voltage inputs.
• Direct and Voltage control (with offset) of Filter cutoff and Resonance
• 1 Volt per octave control of second SID ‘modulation’ oscillator
• Direct and voltage control of modulation oscillator ‘type’; ring modulation, sync or none
• Direct and voltage control of pulse wave pulse width
• External audio input
• Support for ALL SID chips (6851/8580) & SwinSID chips
• All settings non volatile
• Audio output and input at modular levels
• All surface mount single PCB construction thus smaller depth & more skiff friendly.
• Designed and built in England
