If you have a transition fill assigned to main part 1 but still want to go to main part 2 without playing it, it can currently be done in a bit hack-y way.
To put it simple: make sure you trigger a transition and make sure you released the pedal hold before a new bar kicks in. Depending on how you Queue Period option is set this may lead to exactly what you are intending.
What is Queue Period?
- It is a logical separation margin of a bar.
- If the pedal is pressed/hold before that margin, the fill/transition will play imstantly (right at current bar).
- If the pedal is pressed/hold after that margin, the fill/transition is queued to start on the next bar instead.
As far as I recall, the default setting for Queue Period is 75%.
A 4/4 bar with 75% Queue Period looks like that:
[–1--|–2--|–3--||–4--]
Now if you trigger the pedal when playing 1-st, 2-nd, or 3-rd quarter of a bar, what you triggered will play instantly. And only triggers in 4-th quarter will make the fill queue to the next bar.
Now, we come to the next totally not obvious thing: Transition fills are only queued if the pedal is still being pressed when a new bar kicks in!
So, the full answer to your question is:
Press the pedal after Queue Period but release it before a new bar starts.
Doing that way, you will
- play a clean bar from a main part without insta-changing to transition (as the transition is being queued), and
- no actual transition will be ever played as you released the pedal before the new bar started, and a clean bar of next main part will be playing.
Thus you skip the transition.
This solution may seem somewhat flawed, as if you use 75% Queue Period and, let’s say, 200+ BPM 4/4 time signature, you will probably never ever be able to initiate a transition (as you will be holding the pedal for far too little time!). But this exact situation was being evaluated carefully while beta-testing, and this behavior was specifically chosen as it is the most flexible one.
Simply put, you will probably want to use BPM’s in 100 - 150 range as well as set Queue Period to no higher than 50% to use this technique much more easily.
