Waveform Graphic changes with group menu select

There was an error rendering this rich post.

Hi,

I found this code on an old thread but it is missing the on_persistence code. I have tried everything I can think of but can't seem to figure it out! Please can someone put me out of my misery!?

The group select element works as it should but no waveform graphic is displayed.

Thanks in advance!

It's work fine, at home: you must apply again your script, in the KSP editor .

I tested again - it definitely is missing something (the on persistence_changed code). The group menu's work correctly but there is no waveform displayed in the area defined. Just 2 black boxes.

The guy who posted originally on the other forum said " I had to reattach the zone on persistence_changed."

I tried to add this code myself but could not get anything to work. I'm puzzled.

Attach the zones again in persistence changed then. You'll need to store their zone IDs for recall.

Thanks for the reply.

I have tested the above code again on my Studio PC and it almost works properly - I am still not sure why the change of PC has had any impact!

The problem now is that the waveforms only show when I select a group from one of the drop down menu's. The weaveform shows up as it should when I use the dropdown. Is there a way for the 1st group of each menu to be loaded by default?

I still don't understand what code I am missing - the on persistence_changed and storing the zone ID's. Please could someone show me what I am missing? I am very much a novice coder.

Thanks for any help.

I have done some further trial and error style coding to see if I could get it working...

I have added the following code and everything seems to be working properly. The waveforms now show up when I load the instrument and no longer blanks out when I hit the Apply button in the Script Editor.

Is there anything I am missing now?

on persistence_changed

	$event_ID := play_note (60, 1, 0, 1)
	change_vol($event_ID, -200000, 0)
	set_event_par_arr($event_ID, $EVENT_PAR_ALLOW_GROUP, 0, $ALL_GROUPS)
	set_event_par_arr($event_ID, $EVENT_PAR_ALLOW_GROUP, 1, $menu_layer1)
		wait(1)
	$zoneID := get_event_par($event_ID, $EVENT_PAR_ZONE_ID)
	attach_zone($waveform_1, $zoneID, 0)


	$event_ID := play_note (60, 1, 0, 1) 
	change_vol($event_ID, -200000, 0)
	set_event_par_arr($event_ID, $EVENT_PAR_ALLOW_GROUP, 0, $ALL_GROUPS)
	set_event_par_arr($event_ID, $EVENT_PAR_ALLOW_GROUP, 1, $menu_layer2)
		wait(1)
	$zoneID := get_event_par($event_ID, $EVENT_PAR_ZONE_ID)
	attach_zone($waveform_2, $zoneID, 0)

I have been trying to add Previous and Next buttons to each of the 2 Menus for easy navigation between samples. I have got Menu_A and its associated buttons working perfectly but Menu_B's buttons aren't working at all. Can anyone help me please?

Menu_B's code is the same as Menu_A's but obviously tweaked accordingly.

Thanks a lot.

I believe I have finally cracked this. All seems to be working as it should. Thanks for the help.
