Macro presets are something that I would love to see make it into the R3 instrument. For example, the drawbar organ mentioned on the Renoise blog is a perfect candidate for such a system - you can dial in the exact sound you want, but having quick access to a number of presets would be better still.
Implementation-wise, we would need the ability to save presets in the Macro DSP device - or elsewhere? - presets which are then added to the instrument.I could imagine a further extension of the macro device too, with which you would be able to morph between these presets using a special xy-pad alike control. Powerful stuff, considering that each macro might control several parameters in itself!
Questions is where to edit/load/save those presets?
The macro section within the instrument editor could be expanded a little, contain this menu.
The same could be true for the Macro device (in fact, this device already has a preset system - but this is currently defunct not tied into the instrument, but rather the macro device itself. I suggest a Doofer-alike approach where saved presets are made available elsewhere too.
What are your thoughts on this one?
