Matrix 256 Description
There are plenty of circuits out there for sequencers, many are 8, 16, or 32 way, i have only seen one 64 way.anything higher are computerised.
This project is based on a vertical and horizontal matrix, the crosspoints are connected to the 2 inputs of an 'and' gate, if both inputs are high, the output is high
Each output is taken to a potentiometer (acting as a variable potential divider, if connected to a voltage controlled oscillator, you can produce music
Additionally, the same 'and' output could be fed to other switches to activate 2 on/off signals, my idea is for bass drum and cymbal
but these could be used for other triggers. each output includes a 'steering' doide to prevent problems.
There are 16 horizontal steps, and 16 vertical to make up the matrix, it's up to you how you drive this, but my idea is that
any row can be paused or selected,
This project is split into multiple sections for clarity, links are listed below
These links will be added to as videos are made for each board
