Hi,
Buchla Easel V have no midi output. Ableton Live will only record the midi notes, that you send, from whatever you are using as a controller, when you record midi.
You can record the audio output, if you wish. Then you will record, what your hear.
Buchla Easel V has many way's to trigger notes internally, but those notes will not be recorded as midi notes on a midi track in your DAW. The geberated audio will be heard on a audiofile, when you transform the midi track to audio.
If i've misunderstood you, then please feel free to ask again with more detailed informations.
Things going on can be hidden. An image does'nt show what's in the advanced sections. A preset - at least a name of a preset - will help more.
The image you have posted in example show, that notes are being gererated internally by the Sequential Voltage Source. Those notes you will not record as midi. More can be going on in the advanced section.
