Introduction

The Screens are (most of the times) devided into 3 parts

The first row is something like the menubar. The first button is always the play/stop button

The second row is for pages / banks. The Sequencer has 128 steps. 8 pages with 16 steps

The last 2 rows are the buttons to use. It contains the steps, the patterns etc.

The Sequence (Main) View

This is the home view

Pressing the Play button starts the sequence (if there is at least the first step assigned). It leads to the Play-Screen.

The Init first Pattern button sends a program change of the first step. See the MIDI Section below

Load lets you load an existing project. Leads to the Load-Screen

Save lets you save the current project. Leads to the Save-Screen

Clear lets you clear the project. It deletes all Steps. Make sure to save before you do so.

Insert Hold button and press a step, to insert an empty step after the step you pressed. All other steps are moved one back. If you already have 128 steps built, this will delete the last one.

Delete Hold button and press a step, to delete the step you pressed. All following steps move one forward.

The Page buttons let you navigate through the pages of the sequence. Up to 8 pages apear while you fill the leading pages.

The Sequencer interprets an empty step as end of the sequence. If you have 1, 2, 3 and 5 filled, only 1-3 will pay.

The Steps that already have a pattern assigned are marked blue. Click any step (blue and grey) to go to the Pattern-Screen.

Pattern Screen

On this screen you choose, what pattern is played.

Pressing the Play button starts the sequence (if there is at least the first step assigned). It leads to the Play-Screen.

Clear resets the Pattern and clears the Step. Leads to the Sequence-Screen.

Press and Hold the Length Button to acces the configuration for the Length of the pattern. Opens the Length Screen.

Back leads back to the Sequence-Screen.

With the Bank and Pattern buttons you choose the pattern to play. The last used Pattern length is used. Leads back to the Sequence Screen.

Play					Clear	Length	Back
Bank A	Bank B (Active)	Bank C	Bank D	Bank E	Bank F	Bank G	Bank H
Pattern 01	Pattern 02	Pattern 03 (Selected)	Pattern 04	Pattern 05	Pattern 06	Pattern 07	Pattern 08
Pattern 09	Pattern 10	Pattern 11	Pattern 12	Pattern 13	Pattern 14	Pattern 15	Pattern 16

Length Screen

While holding the Length you can choose what length the pattern should have.

Every button is 1/4 of a bar. In the Example, it is set to 8/4 that is 2 bars.

Releasing the Length button will lead back to the Pattern Screen.

Play	Clear	Length	Back

Play Screen

This is visible, when the song is played.

The Playbutton turns red and is now a Stop button. Pressing it will lead back to Sequence screen.

You cannot anything here but on stop

The currently active Page is highlighted, as well as the currently played step.

Empty pages and steps are not emitting any light.

Stop
Page	Page	Active Page
Step	Step	Step	Step	Step	Step	Step	Step
Step	Step	Step	Step (Currently playing)	Step	Step

Load Screen

Lets you choose the project to load

There are 8 pages of 16 projects. Empty slots are not eluminated. Filled slots are white, blue marks the currently active project slot.

Loading will reset every not saved change to the currently active project!

Clicking Back leads back to the Sequence Screen without doing anything.

Play	Init first Pattern		Load	Save	Clear		Back
Page 1 (Active)	Page 2	Page 3	Page 4	Page 5	Page 6	Page 7	Page 8
Project	Project	Project (Active)	Empty	Empty	Project	Empty	Empty
Empty	Empty	Project	Empty	Empty	Empty	Project	Empty

Save Screen

Lets you save your current project.

Saving to an empty slot directly saves.

Saving to the same slot the project was loaded from, directly saves.

Saving to a slot that already contains a project, will ask for permission. (Green: okay - everywhere else: cancel)

Play	Init first Pattern		Load	Save	Clear		Back
Page 1 (Active)	Page 2	Page 3	Page 4	Page 5	Page 6	Page 7	Page 8
Project	Project	Project (Active)	Empty	Empty	Project	Empty	Empty

MIDI Infos / Issues

Program-Changes need a MIDI Channel. The MIDI Channel is set to 10. I will work on a settings-page, where this can be changed.
Currently I am not able to recieve MIDI. I generate a MIDI Clock and send it. This is based on the internal clock of the microcontroller. It is quite stable, but it does not send perfectly accurate clock signals. When set to 100bpm it sends 100.09 bpm and oscillates unregualry by +- 0.01 bpm. I have not encountered isses with that. Its just, that you have 99.9 or 100.1 on the Electron Screen.
Elektron Devices need the Program Change for changing patterns slightly before the actual change occures. Currently I send the change around 1/8th to 1/16th before the pattern ends.
Elektron Devices don't change directly but behave to MIDI Changes like to changes made by hand. They wait until the pattern finishs. If the length of the pattern don't match, this might cause issues, because we cannot know, if the elektron device indeed performed the change.

Stuff on the roadmap

Insert and remove Steps in the sequence, like you add and remove cells in Excel
Build a Settings Menu to change the Midi Channel, Pre Delay for Pattern changes etc.
Understand how MIDI in works, to be able to record pattern changes instead of programming them.
