Re: MarOS - Fresh Firmware - Usability Update 1.3
I did some investigations last night, but it turned out that the last version I posted is all I can do for you regarding the issue(s) reported.
It works all fine when the box is master for your DinSync gear. You can slave the box perfectly to MIDI clock. But when doing both at the same time there seems to be an issue, that not all is reliably in sync every time -although my tests show there is nothing generally wrong. So, we have to live with that. I doubt that the issue as reported is consistent for different setups, I think it`s a bit random how good it all works.
Nevertheless, attached is a new beta with 2 changes:
1) I copied Osmk411`s hack to have better MIDI sync synchronicity: In parameter adjustment mode press A#-KEY to turn on/off the hack. The state is stored on the eeprom, so kept until you change it again, even if the machine is turned off. It adds an additional Sync Pulse (both for the box itself and for the DinSync output) whenever a MIDI-Start command is recieved. This helps for syncing to setups that send the MIDI-Start and the first clock almost at the same time. In that case all firmwares (adafruit, sokkOS) are missing the first clock. With certain environments this is a great help to use the MIDI Sync mode.
2) I improved the internal tempo measuring used to calculate the distance of the clock/Din pulses while slaved, so that it is a bit smarter/safer.. This will reduce timing jitters both for the box and for the sync outputs - not sure if audibly or only measurably.
So, if nothing serious is coming up from you during the next days, this version will be the last, "official" (whatever that means) MarOS. Please do some tests!
