Modification of MIDI Map To Key v2?

[jimbobbley]

Hi all


I perform with Reaper live with a padkontrol using various scenes on the controller, but I've started to run more than 16 songs and need access to more than the 16 scenes the padkontrol will store at one time.

I wondered if I could create virtual scenes within Reaper by using MIDI Map To Key v2, and indeed this will work, but I wondered how easy it'd be to expand this to allow 16 different note on / note off configurations? As it is I'd have to load 16 different iterations of the plug, which is fine, just seems a bit inefficient in the long run and a bit fiddly.

If anyone can point me in the right direction that'd be amazing!

Many thanks

J

I do not have that JS FX. What, exactly, is it that you want to do?

[jimbobbley]

Hey DarkStar

Thanks for the reply.

This is the plug, or just code at end of message (sorry, don't know how others do this and make it neat):

https://drive.google.com/file/d/0B7O...ew?usp=sharing

Basically it allows you to say, for example, when I play C0, make it D#3 instead.

All I really want is another 15 rows of the same thing, so I can leave the padkontrol on the same default scene and have this plug do a 'virtual' scene for each project, allowing me to have more than the 16 it allows on internal memory.

Does that make sense?

Thanks

J

you can use an existing reaper fx for that if I understand your needs correctly

it takes a simple editing of a notes text file to load into it

the JS Fx is "Midi Map to Key V2" MUST BE THE V

so you edit the default text file and save it as your name and then load it into the FX..

and it will change one pressed note to whatever note you tell to output

[jimbobbley]

Sorry, I can't have been clear enough. Yes, I know this plug in does that - what I'm trying to do is avoid having to run 16 different simultaneous instances in every project (it's more time consuming and harder to troubleshoot), so I'm asking if anyone knows a way to add another 15 rows to this plug - ie let me say C0=D1, D2=E3, F#5=B2, etc etc

It already does that, you just need to set up the text file that describes the mapping. It ships with just one "00 - Default Mapping.txt" but you can add as many different mapping files as you want and they will show up in the Mapping File dropdown.

The mapping files live in <REAPER Resources>\Data\ix_keymaps. The default file maps all 127 notes to themselves (ie. does nothing). To change the mapping you just change the number at the start of each line.

If editing text files is too nerdy for you, I made another version which doesn't use a mapping file. Instead it listens for a note and displays the mapping for that note so you can change it then your mapping can be saved as a preset. That's MIDI_KeyMap II and it's in my ancient MIDI Tools II package...

Amazing! Thanks a lot. That's really really useful. And I'm just enough of a nerd to modify a text file, ha... Anything beyond that and I'm not sure!

Cheers

Your welcome. I really ought to update these plugins. JSFX has advanced a lot since they were written. Back then you couldn't do graphics so if you wanted to display a value you had to use a slider, which makes the UI of these key mappers a bit misleading.

I am a little rusty in Reaper , getting back into it , but I seem to recollect that there was a JS plug that could force any input note to a fixed output note.
As in forcing all notes to one note , anyone familiar with that ?
Feel like I used something like that at some point.

Yeah, I think maybe someone made that at some point (it'd be pretty easy). You could use this to do it but it would be very inefficient. You could probably write a custom JSFX to do what you want in the time it would take you to set up a suitable mapping file.
