2 x Waveform Display - Attach Zone Problem

MTC84 · 2024-06-08T09:52:24+00:00

There was an error rendering this rich post.

Hi,

Can anyone put me out of my misery please!?

Currently, the Menu's populate with the correct names but the Menu B isn't behaving as it should. If I select a sample from Menu B the wrong sound is played. It is playing the Group linked to Menu A and not the from the groups linked to Menu B.

Also, the incorrect zone is being displayed in Waveform B.

What am I missing here? I guess it is a simple mistake I have made.

Thanks muchly.

I should add, I plan on having a lot more groups than 4 - this is just a test to get the code working.

theodorech

The overall order of the attach_zone code should be like that:

trigger the temporary event
execute the EVENT_PAR_ALLOW_GROUP code
bring the volume of the generated event down (change_vol or EVENT_PAR_VOLUME)
do the wait(10) thing
add the if statement
attach the zone (attach_zone)

Note that both menus return 0 at the moment, meaning that the second waveform will be assigned to group 0.

Thanks for your help.

I'm not clear on what I am missing but have had a play around with this:

function FUNC_ATTACH_ZONE_A
$Event_A := play_note (60, 1, 0, 1) 

change_vol($Event_A, -500000, 0)


set_event_par_arr($Event_A, $EVENT_PAR_ALLOW_GROUP, 0, $ALL_GROUPS)

set_event_par_arr($Event_A, $EVENT_PAR_ALLOW_GROUP, 1, $Menu_A)

	wait(1000)

$Zone_A := get_event_par($Event_A, $EVENT_PAR_ZONE_ID)

attach_zone($Waveform_A, $Zone_A, 0)
end function

function FUNC_ATTACH_ZONE_B
$Event_B := play_note (60, 1, 0, 1) 

change_vol($Event_B, -500000, 0)


set_event_par_arr($Event_B, $EVENT_PAR_ALLOW_GROUP, 0, $ALL_GROUPS)

set_event_par_arr($Event_B, $EVENT_PAR_ALLOW_GROUP, 1, $Menu_B)

	wait(1000)

$Zone_B := get_event_par($Event_B, $EVENT_PAR_ZONE_ID)

attach_zone($Waveform_B, $Zone_B, 0)
end function

This doesn't attach the correct zone to each Menu either. Any ideas?

You mentioned that both Menu A + B return Group 0. I'm not sure how to fix this part.

Thanks again.

theodorech

You forgot to add your if statement. Additionally, both Menu_A and Menu_B are currently set to 0 as the group index. You'll need to either adjust the menu index when you use the add_menu_item code or increment the Menu_B index by adding one (Menu_B + 1). I think you should check one more time the steps I provided above and make sure you also check my little note carefully. Cheers!

MTC84

I think I am there. I need to do some further testing but all appears correct now.

I actually had to increment the group index by +2 (I have 4 groups in this tester). I will have to change that number when I build the full instrument to reflect the 200 groups/zones.

Thank you so much for the help. You are awesome.

MTC84

After some testing, I noticed I am getting an error for the 2 lines below but the UI seems to be behaving as it should so I'm not sure what is going on. Groups are loaded and purged as they should be. The correct zone is displayed for both Waveform A + B. The Menu's both work perfectly. Any ideas what I am missing?

Thanks!

It seems that you edited the event's name. If it has to be Event_A, you should address that change to the rest of the script related to that event. Example: most likely, Zone_A event doesn't exist. You should change that to Event_A. Side note: you have too much waiting statements. You simply need one to retrieve the zone's waveform. Check the steps I sent you before :)

MTC84

Finally error free! Thank you so much for all your help. I wouldn't have got the answer without you. You're a legend.

I am using Zone_A to address something else in the script. It confused the hell out of me but all is working perfectly now.

My last challenge is sorting the start position and marker on the waveform. I can start a new discussion if needs be but in basic:

I have coded a MIDI CC to adjust the sample start positions and update a visual marker on the waveform to show the user visually. This works as it should. The playhead positions also work for both waveforms A + B.

However, I have an issue - Say Menu A has 100 samples within it and each sample varies in length, the start position marker on my waveform graphic doesn't line up with the actual start position.

If the samples are all say 10secs long, there is no issue. The marker and start position line up.

I'll probably use equal length samples in every group as a work around. This is a drone type instrument but it would be nice to code this so the marker adjusts automatically to the loaded sample's length if that make sense?

Is this possible? Is it a simple task or overly complicated?

Thanks again for everything.

theodorech

You’d possibly use the get_sample_length() or a constant modulator to adjust the starting point of the sample. The first might need some extra calculation in order to scale the accurate point of the starting point (visually) and the latter is more straight forward.

MTC84

Thanks. I will do some research and head down the rabbit hole.
