CYCLE

CYCLE is a modular monophonic sequencer, based on eurorack physical format it has however no patch cables in the front but has rather midi jacks in the back.

It is based on Motherboard12.

NOTE: This is a work in progress.

Features

• 8 steps
• 8 modes
• 8 scales
• 8 octaves
• MIDI over USB
• MIDI over mini jack

Getting Started

Prerequisites

What things you need to make it work:

1 Teensy 4.0
1 MOTHERBOARD12A pcb
1 MOTHERBOARD12B pcb
1 CYCLE front panel pcb
8 vertical potentiometers 10K
1 vertical rotary encoder
9 LED
4 14 pins male header
6 14 pins female header
8 CD4051 multiplexers
8 DIP16 IC sockets (optional)
2 3.5mm jack connectors
1 resistor ~ 22ohm
1 4 positions dipswitch (optional)

In order to run any sketch on the Teensy you have to install the Teensyduino add-on to Arduino. Follow the instructions from the official page: https://www.pjrc.com/teensy/teensyduino.html

Then open the sketch located in the Cycle folder of this repo.

In the Tools -> USB Type menu, choose "Serial + midi".

Then you are ready to compile and upload the sketch.

How to use

1. Default screen
    - Each pair of LED-Potentiometer represent a step.
    - The LED indicates when the step is active.
    - The potentiometer sets the note of the step within 2 octaves.
        - At 0 the note is muted
2. Clock
    1. Usage
        - A long press on the Clock rotary will enter the Clock mode screen.
        - Turn the rotary while in this mode to select between Follower and Leader modes.
        - Press to validate and exit
        1. Leader
            - Sends MIDI clock and song position messages
            - Turn the rotary to increments or decrements the tempo
            - Press to toggle Play/Stop
        2. Follower
            - Synchronize its steps to the received clocks and song position messages
            - Turn the rotary to choose between 8 values to divide the received clock
            - Press to toggle Play/Stop
    2. Display
        - Leader is a slow blink, Follower is a fast blink
3. Direction
    1. Usage

        1. Forward
        2. Backward
        3. Pendulum
            - Going forward and backward alternatively
        4. Sawtooth
            - 1,5,2,6,3,7,4,8
        5. Transposer
            - The bar becomes 4 steps. The 4 steps at the top are being transposed by the 4 steps at the bottom. 
        6. Pendulum Transposer
        7. Alternate Transposer
            - Alternates between 4 top steps and 4 bottom steps being transposed by 1 alternating step on the oposite side.
        8. Random
            - Random steps, avoid repeating notes by leaving blanks.
    3. Display
        - The selected direction is indicated by a blinking LED.
