Been playing with mine today - fun sounds but I'm looking forward to firmware updates!

Would be great if RND didnt affect locked channels.

Exit EDIT mode allways leave steps on the key press you use to leave the mode with, so I have to press 12 for example before exiting to another channel if I don't want a step there - a bit tedious!
Yeah, you are totally right. This and a lot of other features are planned to the next firmware update.

You will be able to random partially or fully each channel that you want instead of all parameters at the same time between other things...

Please, go getting one of the stlink v2 gadget (around 3USD in ebay) to update it when ready if you dont have one yet!

Great!

I bought a partial kit a couple of weeks ago and wonder if it is possible to get hold of the firmware? Eventually I’d like to play around with it and possibly do some modifications.

Cheers

Mine is lying beside the OR and waiting for its first job...

... why buy it for $100 when you can build it yourself for $150?

I just received a pre-programmed Blue PIll and (of course) it works! Finally!!! :sb:


(please, we need a 100% working procedure to update the firmware in the future using the St-Link and and .hex file...I don't want to "break" the current working board, so I have a couple of Blue PIlls replacements...)

I just made a quick demo-jam using the Opera Rotas in sync with my LXR (using Clock Out on the OR)
This thing is wicked!!!

Just finished building mine, it sounds great.

just a warning to others - Don't push the random button if you are using headphones, the volume is seriously unpredictable. (Probably worth running the output into a limiter if you plan on experimenting with the random mode)

I have this wonderful machine too and it is a joy to play with it.
As of right now there is no midi sync?
Did I get this right?
And just in case a FW update arrives, is there already an update procedure?
Thank you for your replies :)

Yes, yes, and no- not yet. Spherical has promised these features in future updates, there are a bunch of interested users, and plans for an eventual open source-ing of the firmware so it will happen sooner or later.... Look back thru the thread, there is a hardware programmer for the blue pill that is needed to do the updating.

Open sourcing the firmware could be very interesting, as I think there are lots of implementations of this machine that could work.
