“am I expected to power cycle the rack or is there another solution to reboot the unit / reload the patch?” – you shouldn’t need to power cycle the rack, just pressing the two tact switches on the daisy should be enough to get it into bootloader mode. Sometimes I find the USB/DFU seems to lose the connection with the Daisy – unplugging it and plugging it back in usually resolves that.
“Using @min/max (0 /1K) for parameter the values are correct in Max but on the Daisy they revert back to 0 - 20K? Is this expected behaviour and if so, is there a way of displaying the correct values?” – I’m not sure what you mean by this. What is K here?
“Will there be a way of adding a 2nd page for the knobs i.e. p1, knob 1-4 does this, p2, they do something different?” – Currently the knob’s action is the same regardless what OLED page is displayed; that is, the mapping of knob to gen~ param is independent of the OLED. I suppose it could be interesting to add a modal aspect to the parameter mapping, which would perhaps be (in gen~) something like [param knob1_page1] and [param knob1_page2] or something like that; but most Daisy targets don’t have an OLED screen so it might be somewhat limited in application.
In the meantime, if you want more parameter control over a Daisy Patch, there’s always the MIDI input. I’ve been tempted to get something like Michigan F8R or Tesseract Sweet 16 for that purpose.
