it has been discussed…for the other Elektrons too…but dont remember the threads…

anyaway,you cannot do what you need. The only way to achieve BPM changes is to use the Arranger

Also there are some special actions to have the BPM changed at the release of FUNCT.

Like…press FUNCT rotate the Level knob to change the bpm - as soon as you release FUNCT it jumps directly to the new value.

There some others that I cannot remember…i swear there was a thread about this particular subject.

When i find it i’ll link it here.

I saw the combos on the Elektron Next Level 2011 pdf document

you can grab it from the marvellous Veets’s site

Then look for this title: OT function+ tempo knob+tap tempo options (2011)
