Using "Supercontrols Send Own Values", Supercontrol appends program change 0

Question

Here's another repeatable anomaly I just found when "Supercontrols send own values" is enabled in Config-Options menu.

Turn on "Supercontrols send own values"

Create a button that sends a program change. Mine is on CH 3 - PC 96. which should produce C2 60 when pressed.

Exit design mode with the Log window up and touch the button. As expected, it sends "C2 60"

Edit the button by touching "supercontrol" in relationships. Do not attach any subcontrols.

Exit design mode and touch the button. Now you get "C2 60 C2 00".  

An extra program change command is appended to the stream, negating the effects of the original program change.

Now create a bank change button, and add it as a subcontrol to the supercontol button.   Exit design mode and test the button.

MD will send the correct bytes for the bank change (B2 00 00 B2 20 01) (CH3, Bank 1), then the correct program change (C2 60) but will still append the extra program change (C2 00).

This issue has something to do with the supercontrol being able to send its own MIDI because I can get it to work if I use two subs with a supercontrol.

Help!

Comments

I would REALLY recommend not using "supercontrols send own values." We'll fix the anomalies as we find out about them (like this one), as possible, but the behavior is mostly undefined for anything but the simplest cases. We'd love to remove that feature entirely (and we might do that for new layouts), but there are a few users of supercontrols-send-own-values that need to remain happy.

In general, steer clear of Supercontrols Send Own Values.

I'll mark this as a defect and we'll likely fix it for the next minor release.

Thanks for tracking this down!

I will gladly forget about it if the next release includes "send program+bank change" functionality.

The only reason I'm mucking with this is to create a page full of buttons that send arbitrary bank+prog changes when pressed.  Creating 90 buttons that each have two subs would be a hugely inefficient use of my time, so I'm trying to put the PC on the button itself (using supers send own values) and using a bank change sub that sends the correct bank.  It would work, except for this bug.

Any timeframe for next minor release?

Thanks

Hi Roy,

No timeframe for the next release yet, and the feature list hasn't been announced yet. I understand that creating 270 buttons and linking them up seems like a lot of work. For a bit of perspective, save your layout and open up the built-in Casio layout. Tap around a bit. That was made by a volunteer user and has hundreds of objects just for decoration, and thousands of little pieces like this.

Sorry for the inconvenience and the mucking, and for taking the hours out of your Sunday for our extended conversations (SOME but not all of which could be repurposed to making layouts). Again, I do NOT recommend using supercontrols send own values and you shouldn't. Take the time to create your layout without using this feature.

Thanks!

Don't misunderstand me: the bug reports are much appreciated, and I appreciate your frustrations with the App. We're working towards making the App perfect for you, but sometimes the schedule doesn't line up with your expectations. Thanks again for your patience.
