Actually, this is not directly supported, but it has been suggested a number of times. I think I'll make a really simple application that does exactly this - TrackSelector or something like that.
The Effect application is mostly designed to control existing effects. Have you tried to add the Mixer EQs first, and then use the application to control them afterwards?
As for assigning specific parameters to a specific control, this is something which is planned. Eventually, you'll get a "effect dashboard" which contain all the favourite effects in that particular song (but we need to figure out how to save script data in songs first)
Haha, yes, actually that would make sense. Currently, any solo button which is pressed would turn off all other tracks by ca3lling the internal solo() API method. This might change, as what you are describing sounds a bit more useful
1 Would be very nice if you implement such a thing!
2 I disagree a bit from my point of view for using existing Effects inside songs. If i wanted to use that i can use a song template with assigned CCs inside Renoise already.
Very handy (but hard to script) would be an Api-function called InsertFxOnDemand
Where options for this app is :
(CC or whatever assignment)
Tracknumber= (if not specified by RowIndex)
DSP Name (Item from List of Renoise Standard DSPs)
Then the Encoders could mapped to
group = "Encoder"
And then a routine which checks wether Fx is already there or adds it into the DSP chain accordingly to Track or RowIndex
3 Looking forward to it !
Thanks for the answers i'm looking forward the next changes
