Please provide the information you are sending (be specific). Are you sending the Bank Select/PC to recall the Performance or are you sending the Bank Select/PC for the Live Set location? It is not clear from your post.

I'm sending MSB/LSB/PC change messages to call up User Performances (e.g. MSB 63 LSB 80 PC 1 to call up that specific user performance as is detailed when you click the properties of that performance). I'm not trying to call from a live set location. Can I do that?Where do I find the necessary PC numbers?

Edit:
I have since got this to work using the details shown in the User Performance Properties display (I had to insert the MSB/LSB/PC instructions on different points within a beat of a bar) however, there is an unacceptable period of sound dropout once the next Performance is called. Almost a bar of music plays before the new performance patches sound. Would this be rectified if I could call the performance from the Live Set location instead?
Cheers

Are you using arpeggios? Sounds like what may happen if an arpeggio needs to finish its cycle. Maybe motion sequence. Just a theory.

Live set information is documented in the "_nf" document which is included with each firmware updated ("New Features" aka "MONTAGE Supplementary Manual").

Live Set
You can now select a desired Live Set Slot by sending the appropriate program change message from an external device. The
Live Set Slots to be selected and the corresponding Bank Select MSBs/LSBs and Program Change Numbers are as follows.
MSB (HEX) LSB (HEX) Program No. Live Set Slot
62 3E 00 00 0 – 15 Page 1, Slot 1 – 16
... continue same MSB below - now just documenting LSB (decimal then hex) for rest
LSB (HEX) Program No. Live Set Slot
1 01 0 – 15 Page 2, Slot 1 – 16
2 02 0 – 15 Page 3, Slot 1 – 16
3 03 0 – 15 Page 4, Slot 1 – 16
4 04 0 – 15 Page 5, Slot 1 – 16
5 05 0 – 15 Page 6, Slot 1 – 16
6 06 0 – 15 Page 7, Slot 1 – 16
7 07 0 – 15 Page 8, Slot 1 – 16
8 08 0 – 15 Page 9, Slot 1 – 16
9 09 0 – 15 Page 10, Slot 1 – 16
10 0A 0 – 15 Page 11, Slot 1 – 16
11 0B 0 – 15 Page 12, Slot 1 – 16
12 0C 0 – 15 Page 13, Slot 1 – 16
13 0D 0 – 15 Page 14, Slot 1 – 16
14 0E 0 – 15 Page 15, Slot 1 – 16
15 0F 0 – 15 Page 16, Slot 1 – 16

Forgive my ignorance but I have never had to use Hexidecimal data entry before. I've only just got my head round standard midi. My external device is a Tyros 4 so the midi data I have to enter is in standard 0-127 numeric format. I hoped to replace my excellent but extremely heavy Roland Fantom G8 with the sleek and light weight Yamaha Montage 7 but I fear this is going to prove too complicated and too much hassle. I'm probably too long in the tooth to start learning how to use Montage to its full potential. ☹️

And you don't have to start using Hexidecimal data entry now...

The Tyros4 will allow you to use standard decimal numbers to input Bank Select and Program Changes. I don't know how "long in the tooth" you are but I resemble that remark, and will measure teeth (proudly) with you at any time! 🙂

Now, let's speak plain English and setup your Bank Select and Program Change info.
What is very important in sending the data is the MSB/LSB must be received first by the device, followed by the Program Change event.

Yamaha sequencers ease the task of sending this three Part message by creating a "packed event", xxx-xxx-xx
So entering the 063-080-000 will select "CFX +FM EP"

Now, yes, you can have your Sequence recall a LIVE SET location using the proper MSB/LSB number and a PC through sixteen..
MSB 062
LSB 000
PC 000-015 to select the slot 1-16.

062-000-000 will select Page 1, slot 1
062-001-000 will select Page 2, slot 1

The first number in the data is decimal. Second is hex.

15 decimal = 0F hex
62 decimal = 3E hex

The table in the new features document (PDF) gives a better table version with the same information (was cut/paste from "nf" doc).

"Program Number" is how Yamaha likes to reference "PC" (Program Change). Typically the distinction is that Program Number starts with a 1 and PC starts with 0. At any rate - if you don't hear the right thing using a program number value - then subtract one (or add one) until you hear the right thing. Kind of a shotgun approach - but just be aware that PC may be documented as one less or one more than the receiving device is expecting.
