After some digging I’m staying with the Uno in stomp mode (upper row in my case). The Uno have the advantage of configuring two CC messages per pedal. I’m been able to switch channels in the VooDoo Labs Control Switcher and turn the plugins on/off at the same time, like a snapshot. To do this, I connect a MIDI Usb Class Compliant cable to the Duo USB port, remap the incoming CC from the FCB (using the “preset” pedals) and send it back to the Duo to process the Plugins on/off. I’m still able to use the FCB stromp pedals to turn plugins on/off. To do that, I’m sending CC messages from this pedals in a diferent MIDI channel (Ch 5) from the preset pedals (Ch 1). That way, I’m able to turn the plugins on/off as stromp boxes or as snapshots by remaping CCs and MIDI Channels in the Duo. I’m also using my Line6 M5 as Wah Wah and Whammy controled by the Duo, with the on/off control been made by the Duo when the FCB expression pedal is in the heel position. The only problem with this configuration, when using the remaped CCs to turn plugins on/off, the FCB stomp status led does not update, but this is a problem commun to every MIDI on-way configurations. To map the plugins to the Ch5 I edited the Duo pedalboard ttl file (it’s the faster and better way to do it ;-)). This way it’s possible to map any plugin to a preset, even if the plugin it’s not mapped to a FCB pedal. I’m using a compressor with my clean preset, and I turn it on when I select the clean preset and turn it off when I select any other preset.
Follows a detailed descrption of my configuration and gear.
- Engl Screamer 50 Combo
- VooDoo Labs Control Switcher (to control the Engl 4 channel/gain configurations, amp boost and reverb)
- FCB1010 with UnO v.1.0.4 chip in stromp box mode (upper row). Version 1.0.4 it’s recomended because it solves the problems with the FCB expresion pedals calibration. I’m using the FCB/UNO Control Center app to configure the FCB (paid but cheap and usefull, http://www.fcb1010.uno)
- Line6 M5
guitar -> Duo input 1 -> Pre gain FX chain -> Duo output 1 -> Line6 M5 in -> Line6 M5 out -> Engl input -> Engl pre amp section -> Engl send output -> Duo input 2 -> Post gain FX chain -> Duo output 2 -> Engl return input -> Engl power amp
FCB1010 output -> MIDI Usb cable IN
MIDI Usb cable OUT -> Duo MIDI IN (this is where to Duo CC remaps will be resend it)
Duo MIDI OUT -> VooDoo Labs Switcher Control MIDI IN
VooDoo Labs Switcher Control MIDI OUT -> Line6 M5 MIDI IN
In attach follows a sreenshot with some explanations. I can publish this pedalboard later if anyone wanted. Follows also a attach with the FCB configuration.
