Ableton Forum

Hi,

I'm making a layered trance melody using Serum 2 in piano roll (Ableton 11). No external midi controller.

It's difficult to explain, but there are some instances where the notes don't seem to play, or have no effect on the overall sound when changing key.

When I play the full midi clip certain key changes don't play, but other times they do. It makes no sense and it really confusing me.

Could someone please help me understand this?

Look forward to your reply,

Many thanks,

Could be the synth's voice limit settings, for example, if set to 3 voices max and you play 4 concurrent notes, one of the 4 notes won't be played.

Could be how most computer keyboards have rollover limits which limits how many keys you can press at the same time, and also some key combinations.

Could be an arpeggiator, that causes keys to only trigger in a certain subdivision.

Could be a LFO/modulation in something like a filter, filtering out sounds.

Could be the synth is fully set to an internal sequencer and actually not accepting MIDI input at all, but somehow sequencer is close enough to your MIDI input that confuses you.

OR THE CLASSIC ABLETON ONE:

Could be you are looking at Clips in Arrangement, but what is playing is actually a Clip in Session View (or vice versa.)

Also check note probability in Live's MIDI editor.

Does it happen with every preset?
Does it happen with another device or plugin?
