I think that the biggest thing that is currently missing is the ability to control the Tonex pedal directly via the Tonex app. I use the pedal in the FX loop of my Helix Floor and control it via MIDI triggers with Helix snapshots. This works great, however, the inability to edit parameters on the pedal in real time with the app, similar to how HX Edit works, is quite annoying when designing presets for a full setlist of songs in a show. I have to load a tone model, sync it with the pedal, and then go to the actual pedal sitting on my floor to make any changes to the preset. It's quite an annoying little dance to have to do. It would be much nicer if I could tweak the parameters of the pedal digitally from my computer while designing sets lists in HX Edit.
In addition, this would make for MUCH easier auditioning of different cabs and VIRs when using the Tonex pedal instead of the plugin or standalone app. The DSP and connectivity of the Tonex pedal seem more than adequate to make this feature a possibility, and I'm sure it would massively benefit all the users that prefer to take full control of designing presets within the app.
Loving everything that Tonex has accomplished though! Seems like it's truly going to be a major market disruptor and I'm excited to see how the product continues to mature.
