For me it would be two things:
- A Kemper Software (Mac & Windows) Standalone and as VST3 Plugin for any DAW - so that you only need your PC interface for recording
- A new Kemper Floorboard with Power Amp and all the features from HELIX and AxeFX. Mostly more Stomp Sections and the abillity to have mixed cab simulations for individual tones.
Then they could go the extra mile and include:
- A Feedbacker (like the DigiTech FreqOut)
- Sweetend Tunings (see Ed.Van Halen)
- Compatibillity with Neural Amp Modeller
- A specific Kemper Audio Driver and Audio Codec
- A Graphic Audio EQ where you can Compare 1:1 what the "Real Amp in the Room" Freq. Curve is to compare and experiment
