Hi,
Look, I'm probably speaking on a totally different subject here but having read Technic Player's reply, he's quite correct.
When we step record a piece of the KN6K we use track 6 as the control track. All we have to to do is go to the part of the 'score' where we want the change to take place and, using the control wheel, alter the tempo as required. We're then asked to confirm the change and, lo and behold, that's it.
I think the major problem is that various MIDI sequencers / performers don't always use the same track number for control and it can be a matter of some guess work as to find where they've hidden it.
Regards,
Lucy
