MIDI Expression 2.9.3 BETA is available

[Rob]

Thanks for the feedback.

This is great news about 14bit CC and the ability to support 3 switch pedals. I'm really looking forward to trying that out (though very few devices or software support it - interestingly good ol Ableton Live does support it, as did the old Behringer BCR2000)

Anyone have an existing easy diagram of how these 2 switch pedals are wired? I'd like to connect three momentary buttons to one input.

I just got my Midi Expression interface to use it with the TC Switch 3. I upgraded to the latest 2.9.3.10 firmware and tried it out. Unfortunately it seems not to work for me - if I select the 3 button footswitch, the press of the 3rd switch is registered as presses switch 1 & 2 together...

Thanks. I'll investigate.

I don't actually own the TC-3, but rather made the circuit myself. Looking more closely at the schematic for that footswitch I see that the forward voltage drop of those diode is 1.1V, but the diode's I used during testing were the typical 0.7V. I'll order some new diodes and make the needed adjustments.

Can you give build 11 (linked on the first post in this thread) and let me know if it gets your 3 button footswitch working properly?

Just downloaded the new version and tried it out - unfortunately still no success. The third button of my TC Switch 3 is still recognized as a press of buttons 1 and 2. And in the firmware section the new one now shows up as 2.8.3.11 ... (and the Midi Expression Control app asked me to downgrade the firmware version)

I accidentally typed the wrong build number. I'll fix it when I get home in about an hour. The firmware will definitely need to be updated for the pedal to work properly.

Should be good now. Redownload and reinstall.
