Long awaited MidiALF firmware upgrade is here. New features include:
- Conditional triggers for Note, CC1/2 and re-trigger, similar to the ones found in Elektron RYTM and Digitakt. No more static sequences, spice them up periodically, randomly or manually by pressing the SHIFT key!
- Note, velocity and CC1/2 randomization. Note value can be randomized according to a selected scale which can be different for each step of a sequence. Try mixing different scales in the same sequence, endless joy!
- Note re-triggering, 2-16 per step, velocity and pitch modulated, chromatic or restricted to a selected scale. Also can be conditionally triggered. Now you can ratchet just like TD!
- Song mode: up to eight steps, each specifies the sequence to play, how many times and at what transposition. Chain sequences creating songs!

Where is the link to download the firmware?

Thank you
Amazing!!
is there an option to configure encoders behavior ? i’ve bought chinese ones and they are decrementing instead of incrementing. this is a simple trick in the code where you set clockwise and counterclockwise regarding increment/decrement. ideally this would be in the Config section of the midialf directly accessed from the Menus
There is no such option, however those who have this problem simply rebuild the firmware making one simple change in the source code.
thanks for your reply. do you have a link for the midiAlf v2 sources in this case please ?

Hi Alpesmachines,
If you need any help with this i would be happy to lend a hand. I am about to recompile the source with some changes of my own.
@kvitekp – do you mind if the source is hosted in a public git repo?
Actually I do because i’m planning to publish it on github at some point and would prefer it to be forked. Just need to resync my changes to avrlib so it could be forked from Olivier repro.
@kvitekp – no problems at all, that would be perfect.
I just spent last night familiarising myself with the new code.
Hello,
I have built a midialf and programmed with midialf V2 hex files.
I’ve been able to programmed the Atmel 644PA but after that, when I power on the sequencer everything is really going slowly.
I.e : the ignition sequence is really very long. After that, if I turn one encoder it’s really long too and it takes a long time to go from one step to the next one. Everything is really longer that it should.
I have used the original BOM, respecting encoders type and all the recommendations….
Do you have an idea ?
best regards
Otto
I’ve finally found my problem. It was a bad fuses configuration.
I haven’t selected the right clock parameters. Now it works and I have learned something new 🙂
Thank you for your works and making this project free !
(feel free to delete my previous message if you want)
Best regards
Otto
Yeah, that’s what I thought. Congrats on the successful build!
You may want to verify that you’ve burned the correct fuses, see here: https://midisizer.com/midialf/midialf-build-instructions/flashing-midialf-mcu/
Many thanks for the v2 firmware! I’ve only discovered this 4.5 year too late (…). I dusted off my MidiALF and burned the v2 firmware, after which lots of new functions and a better GUI appeared.
Very nicely done! I just need to finish a proper case for the MidiALF now.
If you have access to a 3D printer, I have a pretty nice design for a MIDI only MidiALF case.
Thanks for the offer – but I have one with CV, and there is also going to be a (somewhat stripped down) Shruthi inside the same case, mounted horizontally (with the two board next to each other), underneath the MidiALF+CV.
That’s why it is taking more time 🙂
Good luck with the project!
