Two different commands on same control? BCR2000

Hey, 

Long time no see, this is genmce from "back in the day", I'm trying to resurrect my BCR2000 for use!

I am working in Reaper with BCR2000 and CSI3 plugin.

I am wondering if I can stack two different commands on the same knob? 

I am looking to be able to turn on a plugin parameter like reverb on/off with either a cc or note

and adjust parameters of that reverb size or decay based on a different cc.

Can two commands be sent from same knob? I'm guess this would be a custom message, I've been away too long.

Thanks

Yes, you need a "custom" definition, which can consist of up to 125 bytes.
You can even use a "standard" definition and a "custom" definition together for the same BCR element (button or encoder); in this case the BCR always outputs the message defined via the standard definition first.
One advantage of a standard definition is that the value of the BCR element is updated when the linked device (in your case Reaper) sends a message to the BCR using the same CC number (or NRPN etc.) on the same MIDI channel. On the other hand, a BCR element doesn't update its value when the BCR receives a message that concerns the element's custom definition. So the idea is to put the "main" definition in the standard definition, and the rest in the custom definition.
See section 14.6 of BC MIDI Implementation.pdf for further details.

Hope this helps,
   Mark.

Thought I posted a reply... ah well.

Thanks for reply - I am looking at that section you recommend.

The specific behavior I'm looking for on the custom definition: When knob is turned past 0 send 1 "note on"  no more. When knob reaches 0 again send "note off". Is that possible? I don't quite understand the syntax to write that kind of message.

I can't figure out how to edit a post, perhaps that is not allowed?

So maybe I won't need the note off. 

I have a relative knob ... what I am after may be impossible with a relative knob, because it never reaches 0. I will try to drill down to what I need specifically then post back. You can delete my previous post, as it's not thought out enough. Thanks

No indeed: when I set up this website, I decided to disallow users from editing or removing their posts, because this can easily lead to "historical confusion". For instance if user A changes a post to which user B has already responded, then user B's post may become incomprehensible.
A related point: to stay below the maximum daily number of outgoing emails allowed by the webhost, the website sends subscription emails in batches: each batch consists of up to 50 emails, and there are 3 hours between consecutive batches. So when a user changes their post, some people may already have received the original version, whereas the rest will receive the updated version. This would be very confusing.

Of course there are also drawbacks to disallowing editing posts. For instance, people can't correct typos etc. But we'll survive typos...

You can delete my previous post, as it's not thought out enough.

For the reasons outlined above, I'll let it stand: if I deleted it, people reading your request to "delete [your] previous post" might start wondering whether it refers to your original post.
So I guess the bottom line is: never try to change the past [emoticon:smiley]
