This expander adds two additional channels to µTune. Each channel has a CV-in, GATE/FREQ-in, CV-out and GATE-out. Functions for each output can be assigned freely.
An additional LED shows the state of the gate outputs: Channel A in blue and Channel B in red. The led is green normally to indicate proper connection to the host.
Up to three expanders can be added to µTune for a maximum of 8 channels.
The expander houses a complete microcontroller system used for AD/DA conversion, frequency measurement and communication with the host µTune module. The expander is essentially a complete µTune, but without display, buttons and midi connections.
Like µTune, each expander is calibrated and tested by Tubbutec prior to shipping.
µTune and expanders feature a flexible voice allocation. Channels can be grouped and each group act as a separate polyphonic or monophonic voice group. See the µTune manual for more info.
