I am having trouble passing MSB and LSB values into the bank helper.

I am trying to convert 2 integers into MSB and LSB values to pass into the bank helper via variables. I can't figure out how to properly convert the values to the expected format, nor find an example, and I would greatly appreciate if an example could be added.
This is what I am trying to do:
myMSB = bankSelectMSB.toString(16);
myLSB = bankSelectLSB.toString(16);
smf[smf.length - 1].add(index, JZZ.MIDI.bank(channel,parseInt(myMSB, 16), parseInt(myLSB, 16)));

Hi! Thanks for asking!
If you have the bank MSB and LSB as numbers, you don't have to convert them to anything.
The easiest way to add the bank messages to the MIDI track would be
smf[n].bank(channel, MSB, LSB);
Please check https://jazz-soft.net/doc/JZZ/midifile.html for more details.
You can also look at this: https://github.com/jazz-soft/test-midi-files/blob/main/code/test-control-00-20-bank-select.js

Thanks so much! My mistake was that I trying to use .add to put the bank select where I wanted it.
I changed my code to the below which does not throw an error:
smf[n].tick(index);
smf[n].bank(channel, MSB, LSB);

Just a note: you should chain your calls, otherwise the bank select goes to the tick 0:
smf[n].tick(index).bank(channel, MSB, LSB);

To follow-up your question...
In the latest version, I have added the ability to accept compound messages, e.g.:
track.add(tick, JZZ.MIDI.bank(channel, myMSB, myLSB));
Thanks again!

Thank you!
