Input Monitor Routing

Holding the Shift key and pressing down on the Volume encoder will now toggle between 3 different ways to route the input monitor. Position 1 is the default unless changed in the options.json file (see below).


  • Position 1 routes the dry monitor of the selected input to the CHOMPI Buffer, which will output to the Headphone Output ONLY, whenever the mode switch is in the UP position


  • Position 2 routes a wet monitor of the selected input through the FX and Looper engines, before outputting an identical signal to both the Headphone and Line Outputs


  • Position 3 routes the AUX Input to the Headphone Out ALWAYS, even if a different input is selected. The Master Out is then used as an FX send and the AUX Input is the return, with the Headphone Out dedicated as the main output


User Options File Configuration

CHOMPI has some new user config options available in the “options.json” file located on the microSD card. Options include Record Latch, MIDI In/Out Channels, Tape Slew On, Monitor Position, and Pitch Quantize In Shift Menu.
