1) Fix the Sync modes in Track mode
When I previously rewrote how sync is managed in the "edit" modes of pattern play, I totally ignored Track mode.
Here I fix this.
Also fixes issue when pressing "Next" in track mode would cause desync of clock. If anyone wants to test this change:
https://rv0.be/tmp/yocto_firmware_1_2_Track_Mode.syx

2) Fix sync issues in pattern edit when using midi slave mode
This should also improve the Tap entry and Tap-removal
If anyone wants to test:

Have fun

Thanks for your work!
Do the two files contain both fixes, or each of them is one fix - based on 1.2a?
Will you merge those fixes into 1.2b eventually?
Thanks,
Flavio.

Each of them is one fix for testing purposes, as they are quite unrelated code-wise.
Please help by testing both version in your setup

The code has been submitted for review on the official-unoffical repo maintained by helectromagneticus
https://github.com/HomoElectromagneticu ... _808/pulls

I'm sure once he finds the time to have a look at the changes and test them that he will merge the changes and create a new release.


I started doing a major refactor btw.. But there's a ton of work to be done.. Basically changing the whole way the sequencer works under the hood... But thats for later.. Probably not for this year even If @helectromagneticus is reading this, please help me decide on code style, as things will go a lot quicker for me after doing an automated reformat on _ALL_ the things

Wow! This is great! I will look over and test the new changes this weekend.

I love the idea of a refactor. I was actually just poking around in the code the other day to try and get the MIDI sync tighter. And I hear you about the code style being a bit messy...

you have problems with midisync?
apart from issues in edit mode (fixed in latest PR) i wasn't aware of issues there..

as for refactor: yeah.. I started doing some things, but it's far from finished:
- only 1 method for playing a pattern, not 1 per sync mode.. the code should not have to worry about which sync mode it is in
- removed all code from interrupts.. just incrementing a counter in there
- make the trigger stuff a lot less voodoo (will make a lot of things more stable)
- make all sync modes 96 ppqn: this will allow shuffle and also a more uniform roll mode
- some ideas to make roll mode a lot better / flexible

This will take a while though, It's also a learning process for me.

I tested rv0's code and it works great on my machine. I think there's still some weird behavior to work out in Track Edit mode while MIDI synced, but rv0's changes are a good step forward for sure. The new release is up on github:
https://github.com/HomoElectromagneticu ... /tag/v1.2c

My problems with MIDI sync are pretty general. I don't like the delay inherent to using MIDI clock and am looking for ways to reduce the time it takes the Yocto to handle a MIDI message in hopes of reducing that delay time. I haven't put too much effort into that because I know MIDI can never be as tight as DIN sync anyway.

Some of your refactor ideas are really great. I especially like the idea to have only one function to play a pattern. In reality you may need at least two depending on the clock type (24PPQN or 96PPQN).

Stripping the interrupts down should be approached with some caution. To my eyes, it looks like there's some magic going on there.

What voodoo are you referring to in the trigger out code? If you're talking about the calls to digitalWrite(), then I agree that a better and faster solution could be found. One would just need a bit of code implementing a shadow register for PORTB on the microcontroller.

You won't be able to get 96PPQN in all sync modes. MIDI sync is only 24PPQN sadly.

I would love to improve roll mode - there is some weird stuff going on with that.

As usual - thank you guys! You're doing great work on this firmware!

let me know if you have more info on that, it should be fixable

I got an idea about that. A lot of machines have higher internal clocks even when synced to midi, so I don't see why the yocto cannot..
Initial plan was to make it all 24ppqn as it's pointless to have a total different machine and functionality when using internal sync. Having 96ppqn means we can have shuffle and crazy rolls in all modes.

I don't like magic

BTW: is anybody looking into Nava firmware as well? Not necessarily you two guys, just asking out of curiosity...

Sorry to sound stupid but im terminally challenged with modern pcs. Anyone willing to burn me an AT of this unofficial fw?

I'm still working on the firmware, so there will be more updates and new features coming this year at least from me... So I would really recommend to learn it so you can update as new versions appear, it's not difficult at all.

This is how I do it:
Initial setup:
1) Make sure you have a midi interface connected to your pc.. I use an older version of https://www.esi-audio.com/products/midimateex/ .. Connect midi out to the Yocto midi in
- Download and install Elektron C6: https://www.elektron.se/wp-content/uplo ... N_1.51.zip (there's other tools, but they need more advanced config, this just works out of the box, for now, it's end of life).
2) Open C6 and configure midi output (Config) so that it sends midi to a cable that goes into the Yocto's midi in. If the delay setting is 0, set it to something like 16, that setting works for me, but its very randomly chosen I think
Once that is setup:
- Download latest Yocto.syx from here https://github.com/HomoElectromagneticu ... 8/releases
- Open the Yocto.syx in C6, make sure it is selected and put your mouse pointer on "Send" (don't click it yet)
- Power on the Yocto holding keys 1-3-5, and quickly (within 5 seconds) press "Send" in C6
- You are now transfering the firmware (Rolling LED animation on yocto). Once done, you've successfully updated the firmware


Good luck! If you get stuck people will help you, don't worry!

Amazing! Will try tonight!!! HUGE THANK YOU!!!
