I ordered the chip and labels separately as there were no labels in stock and I didn't want to wait too long for the chip. Now that a new batch of labels had arrived I received an email saying they would send a free chip-upgrade with the labels. Praise to Xavier at uno4kemper.com for excellent CC.
Here are the details about the new firmware. I assume the information on the uno4kemper.com site will get an update soon:
"What's new in this firmware ? A number of changes were done in order to improve the expression pedal behavior of the FCB1010. After a lot of finetuning and testing, the "hysteresis" is now reduced to a minimum, which means that the slightest movement of the pedal will now cause the volume or wah to respond, while earlier versions required some more pedal movement before the adjustment kicked in. Along with that change, also the adjustment resolution has been improved. But the most important add-on of firmware v.1.2 is the possibility to choose the "sweep curve" for each of the 2 pedals independently. Up till now the FCB1010 expression pedals showed a more or less linear behavior, which is far from optimal for volume or wah adjustment. A volume pedal normally uses a logarithmic "audio taper", and a wah pedal typically has something between audio taper and linear taper. WIth the new firmware, you have 5 different sweep curves to choose from , going gradually from linear to audio taper. You will notice that this results in a far more natural volume and wah adjustment.
I didn't have the time yet to extend the user manual, but by the time you receive your chip, please check our website for a new manual, which mentions how to configure the 2 expression pedal sweep curves. "
