setBFree - Customizing Leslie speed (and other config parameters)

Software
1

Hi all,

I want to change the speed of the Leslie in setBFree.
In the interface Zynthian, nothing about the speed of the two speakers (low speed, high speed, acceleration, deceleration for the two speakers)
I tried to change the default.cfg after a reboot, no changes.

what is the good cfg file loaded by default ?

Thanks a lot.

Antoine

Try adding your changes to this file:

/zynthian/zynthian-data/setbfree/cfg/zynthian_my.cfg

Note that this file will be overwritten when updating your zynthian. To avoid this simply add the modified file to .gitignore.

Ups! Ignore my last comment! I just remembered that i moved the config to a better place so customizing is easier and persistent across updates. Please, put your customization in this file:

/zynthian/config/setbfree/zynthian.cfg

No need to reboot to test your changes. Simply reload your setbfree processor by reloading your snapshot or remove/re-add the setBfree chain.

@jofemodo I’ve found I do need to reboot for the changes to take effect, just reloading the snapshot doesn’t work (for me anyway).

I highly recommend folks tweak the leslie settings! I currently have this, might be a little slow but I like it:

You have to destroy the setBfree chain and load the snapshot after. Reloading the snapshot will try to keep the engine alive for faster reloading.
