MIDI Features
The Hub v1 uses MIDI PC messages for saving and recalling scenes. Additionally, the Hub can also
respond to MIDI Continuous Control (CC) messages and MIDI Clock.
MIDI CC messages received by the Hub are passed on to the connected Soundblox 2 pedals. The
function of each CC number is hard mapped to pedal functions across the Soundblox 2 line. The
implementation table is available at the end of this document. Each pedal type has an assigned
CC number mapping so that they can be used as a single system when connected to the Hub.
The Hub can also accept MIDI Clock messages to synchronize LFOs on Soundblox 2 pedals that
support this function. This allows an external MIDI device to set the LFO rate on an effect by
sending a MIDI Clock stream to the Hub. The MIDI Clock is sent to simultaneously to attached
pedals so it’s possible to use MIDI Clock input to synchronize LFOs between two or more pedals.
The MIDI Output functions as a MIDI Thru connection by default. This means that any incoming
MIDI messages are immediately sent back out on the MIDI Out jack. However, it’s possible to use
the Hub Manager application to change the mode of the MIDI Out. For example, it can be set to
take incoming Expression and Hot Hand messages and send them on the MIDI Out as Continuous
Control messages. Other modes will likely be supported in future firmware/software revisions.
