I have 2 questions:
1: note retrig like in the analog rytm (step + arrow up) is not possible on the A4?
2: how can I make such basslines like these tracks with the A4? I have a hard time to find the same wideness
or chorus effect on the A4
youtube: Extrawelt Added Planet (bassline around 1:10)
youtube: dj koze’s remix it’s Only (also around 1:00)
You may use ARP for such thing
Bass sounds may not be that easy to get with A4. I mean, it needs you to take the time to focus on this a few days and see how to get different bass sounds.
A good start would be analysing the Bass Vol. 1 Pack
The arp has no velocity change such as the retrig in the Rytm?
Bass pack presets:
done already, not really what I’m searching for 
anyway thanks
For wider bass you could try unison with the stereo spread turned up.
Also, lots of tips for bass in an old thread. A4 deep bass tips?
Yes the deep bass tips with the filter tracking pitch i already knew and is a good tip. Ill.try your unison tip thanks
