There are no microcontrollers used in this design. It is comprised entirely of CMOS logic and analog opamps, so does not suffer from aliasing or any other issues present in a microcontroller-based design.
This also means you can get all the parts straight from a parts store and not have to program a microcontroller, if you want to source your own parts!
- Consumes ~15mA @ +15/12/9V
- Does not need a negative supply rail
Easy to Build
- PCB mount step controls make the design easy to assemble
- Economical design can be built much cheaper than commercial solutions
- Tempo control
- Selectable sequence length (1-8)
- Simultaneous 5V and ~10V CV and Gate outputs. This means you can use sympleSEQ for pitch CV as well as higher amplitude stuff like filter modulation
- Flexible clock input accepts a wide range of voltages to clock the sequencer from
- Clock output
- Pause and Reset switches
- Pause and Reset inputs (Voltage high = active)
- Input a variable pulse-width clock and control the gate length by adjusting the pulse-width!
