Hi organ lovers!
I just pushed some improvements to the setBfree engine that increases its possibilities as a combo organ emulator:
Available on vangelis. Just update and enjoy!
The best!
Can you elaborate a bit on the waveforms. In setbfree on a regular system (package-manager provided), I cannot choose between different waveforms at all. Is this a recent addition to setbfree or is it that zynthian provides the waveform for setbfree to handle?
IIUC the B3 only produced sine waveforms, which were altered by the preamp.
Of course experimenting is nice, but what choice of waveform in Zynthian comes closest to the original sound?
Hi @niels!
Waveform selection is part of the “new engine” wizard that you step through when adding a setBfree chain. Sine is the default as it matches the B3 tone wheels but setBfree offers alternatives for those who want more harmonics in their sound.
the alternate wavesforms are a zynthian tweak over the setBfree engine. You won’t find this on the repo package.
Thanks for the explanation. Currently it seems impossible to switch waveforms without removing the processor and adding it again. Are there big obstacles to make this possible?
Is everyone here just using a single manual of setbfree?
I created two issues with multiple manuals on Vangelis January 10th, but they have not yet received any activity, which strikes me as odd, especially since (nice) stuff like this is being developed.
By the way, to answer my own question: yes, there are (probably insurmountable) obstacles to switching waveform on the fly: a config file is written containing the required waveform, after which setbfree is started.
Yes. We could restarte the engine quite fast, but changing waveform without stop playing is not posible.
But perhaps it’s time to remove the one-instance limitation… i think now it’s possible.
Regards
Be aware that setBfree runs all of its processing continually, i.e. it does not ramp CPU usage based on playing. Multiple instances could add substantial resources burden.
setBfree is really light, and It is the user who decide how many instances. I’m not thinking of running several instances in one processor.
But the best option would be implementing waveform change inside setBfree code. It shouldn’t be too complex.
I find this issue really annoying.
i will fix ASAP
Grazie boss!
It’s fixed on Vagelis.
I don’t know if the issues are also present in Oram, but i’m not going to solve because Vangelis release is not far and current Vangelis status is quite stable 
On oram there were no such issues. Thanks for fixing, will try it soon!
Fixed!!!
Almost working. We re-adding setbfree with multiple manuals, the controls and option pages for the second manual are unavailable. Luckily, an error is thrown:

Sorry, I was too happy for fixing but I tested with upper mode only.
I confirm that no controls and option for second manual.
Sorry, i can’t reproduce. Please, steps to reproduce.
Regards,
OK guys! I could reproduce. Let me fix it …
