Firmware version: 0.95
There are two types of UI pages: top level pages and command pages. The top level pages are:
- sequence settings
- progression settings
- system settings
- CC LFO1
- CC LFO2
Top level pages can be selected by rotating EncB at the right of the screen. First 8 top level pages can also be selected directly by pressing one of the 8 step switches while holding down SEL button (at the bottom on the right side).
Command pages are shown by selecting a command from the Command page that could be activated by pressing and releasing SEL button alone. These are the currently available command pages:
- Send sysex
Load and Save pages could be invoked directly by pressing SEQ and SEL+SEQ buttons respectively.
When the top level page is shown, rotating EncA at the left of the LCD screen changes all steps of the currently selected sequence and clicking EncA allows copying of the currently selected sequence to another one. When command page is shown, rotating EncA results in page specific action, however clicking it closes the currently shown page returning to the previously shown top level page (aka Escape).
Rotating EncB at the right of the LCD screen while the top level page is shown cycles through top level pages and clicking EncB shows the Note page or the Sequence Settings page if the Note page is already shown. When command page is shown, rotating EncB typically selects an item while clicking it carries out the page specific action (aka Enter).
EncB rotation cycles between the top level pages: Note, Velocity, Gate, CC1/CC2, three Settings pages and two LFO pages.
EncA click shows Copy Sequence page if a top level page is shown, or closes the currently shown command page.
EncB click shows the Note page or Sequence Settings page if the Note page is already shown.
Step Encoder rotation changes the step value.
Step Encoder click “plays” the step sending it’s note and CCs to MIDI OUT.
Left side switches select sequence A, B, C or D.
RUN starts and stops sequencer.
SEQ shows the Load page.
CLK cycles Clock Division slowing down the sequence by 2 or 4 times.
If the SEL switch is held down, the following switches’ action is altered:
– SEQA sets set Link Mode to None;
– SEQB sets Link Mode to 16 and selects sequence A;
– SEQC sets Link Mode to 16 and selects sequence C;
– SEQD sets Link Mode to 32;
– RUN toggles Recording mode;
– SEQ shows the Save page.
– CLK toggles “step hold” mode.
Pressing the step switches 1 to 8 while holding down SEL switch shows Note, Velo, Gate, CC1/CC2 and settings pages.
Rotating encoder while holding down SEL switch increases increment to 10 or an octave.
Lone SEL switch shows Command page.

Nonlinear sequence progression parameters are borrowed from MIDIBox SEQ v4. Thank you, Thorsten, these are a lot of fun!

System exclusive message format
MidiALF firmware update steps:
- Backup your sequences to sysex file using Send Sysex page [All]
- Connect your MIDI interface output to MidiALF MIDI IN
- Power on MidiALF while holding down the EncoderA. MIDI LEDs will blink shortly then MIDI IN LED will stay steadily lit. The display will remain blank or contain a line of box characters.
- Send firmware update sysex file (*.syx) to your MIDI interface port with 250ms delay between sysex buffers. Elektron’s C6 works great on OS X and Windows. Classic MIDI-OX is also good on Windows. MIDI LEDs will be blink while firmware sysex is being received.
Firmware update takes a couple of minutes, MidiALF will automatically reset when the update is done. Check the version number display on MidiALF startup page.
Most firmware updates do not require MidiALF memory to be reset. However, if you don’t find your parts and songs after the firmware upgrade, please restore them by sending the sysex back up you created at step 1 to MidiALF MIDI IN.
Power on MidiALF while holding down EncoderB to reset it to initial state. Note that this will wipe out device memory without any confirmation. Use this to restore MidiALF operation as the last resort.
