I think the A4 is my favourite Elektron machine to date, I loved it from day 1 when it was in beta, the various enhancements added since then have made it even better, people’s tastes and requirments differ though and that is cool with me. As an instrument I find it to be very flexible and easily able to be used on its own to do complete minimalist jams, the sound locks and flexible architecture allow me to work within a limited but not too restrictive framework that I particularly enjoy.
I wish that there were a few more routing options WRT modulation destinations from the LFOs and envelopes, and I wish that the illogical scale page was sorted out - but this is the same on all Elektron machines.
The trig conditions are really great, I think that a few extra enhancements here would make the sequencer even more flexible though.
Overall I find it the easiest Elektron machine to get sounding good quickly, it seems to have far more sweet spots than the AR and MD possibly due to its more open architecture (no ‘machines’) and it is also my favourite Elektron for analog kick drums.
One final thing I love about it relates to my use of nanoloop mono, due to the similar architecture of the sequencer and sound generation (although of course the A4 is more featured) I can use nanoloop mono on the go to come up with ideas then quite easily translate the patterns into the A4, or vice versa with some omissions. Combining the 2 quite different approaches to pattern creation is a nice way to encourage me down paths which I might not have travelled otherwise.
But yeah the A4, a classic in my book.
