Up until now I have have not needed a midi controller while using the Aeros. Now we have a reverse function that’s changed. The midi maestro looks great but a bit pricey just to access a reverse function. I don’t have Beat Buddy and I just use the Aeros in my home studio so no live work so I cannot see what other benefit i would get from the maestro.
If you have time for some patience on this, we may have a solution for you without a MIDI controller soon, but in the end the MIDI controller will be much better at doing exactly what you want without too much tapdancing. You may want the MIDI controller in the end even if we can make this handsfree on the Aeros.
