Logic

Fixed-function Logic module using CD4xxx logic chips

Logic

A straightforward, no-nonsense quad logic processor. Triggers, gates, audio - whatever you want - can be mangled, merged and digested by logic gates and the result used in creative patches.

When fed audio, Logic will convert the audio into square waves. This can be pretty handy for making suboscillators, especially when combined with a clock divider, and adding a bit of beef to an otherwise less interesting waveform.

Applying clocks and gates to the module can be especially helpful in creating generative rhythms and beats with different logic chips resulting in wildly different patterns.

Inputs are copied down the A and B inputs (normalled) if nothing is plugged in, saving from needing to use multiples to split commonly used signals such as a clock.

Technical Information

• Quad logic gates, with a fixed function. AND, NAND, OR, XOR, NOR, XNOR operations are available
• Inputs on over 1.2v, off under 1.2v
• Outputs at 5.5v
• Negative input voltage protection on signal inputs

Availability

Available on Reverb, or as a DIY kit from Tindie
