Feedback on 8 vs 16 GB is very mixed here. Interested in an M2 over M1 only because it has more inputs.
I would use it for recording and arranging several audio tracks in Ableton (live record max. 4 tracks at a time, editing so far max 25 tracks) and have a few effects plugins running on these tracks.
No VSTs so far, but having the option to later add 1-3 MIDI tracks with VSTs would be nice. From what I hear, 8GB should be enough for that? The price increase for 16GB is huge as there are many deals for 8GB but not for 16.
