Great concept but needs work

App is able to get pretty close to most tone clues you give it but parameters that are given OFTEN do not align with the options for that model pedal/amp etc (amps that don’t have presence setting, compressors that don’t have sustain, cab terms, etc). Would think this is an easy fix as it is very clear what options the preloaded efx in the QC have on them…just not sure why doesn’t match and can leave you with tone that is “off”

Cortex studio disappointment

I love the layout but the app is constantly makes parameter suggestions that aren’t available on the suggested devices. I.E. sustain and attack on a jewel compressor or suggesting a mid settings on a UD DLX 64 Vintage
