Oh man I just figured something out in 2.5.
"Controlling renoise… with renoise!:
I don’t have my glasses with me so I won’t go into too much detail, just how to do this.
You must have some sort of midi router to begin with, OSX (IAC) and linux (jack & alsa) have this, in windows use something like midi-yoke (it works perfect)
-I’ll try to make a recording of this once I find a decent screen capture for OSX.
You need at least 2 instances of renoise open for this renoise on renoise fun.
you can either do this synced or non-synced.
Synced entails making one renoise a master & the other a slave,
In the midi prefs of renoise(Master) in the middle at MIDI CLOCK Master select the routing device, such as IAC Bus 1, Out to MIDI Yoke:1, Midi Through Port 0
On instrument 00 go to the Instrument Settings, to the MIDI Properties then Device select IAC Bus 1, Out to MIDI Yoke:1, Midi Through Port 0
now that is set.
now go to the Track DSPs
insert a Meta MIDI Control Device, as the instrument, make sure 00 MIDI (cha 1) is showing.
Go to one of the “Untitled” sliders and give it a CC number like 22. (make sure the CC is next to it)
Now insert a LFO meta device in the same track and link the destination to that slider you just set up.
The slider should be moving at this point. and this slider is what we will use to begin telling Renoise (Slave) what CC controller we are using.
Now on to Renoise (Slave)
Of renoise (slave), goto midi prefs, at the top MIDI Master Keyboard / Midi Mapping:
In Device A, select IAC Bus 1, Out to MIDI Yoke:1, Midi Through Port 0 remember that is whatever you chose it to be in the instrument 00 of renoise (master)
Then at the bottom at MIDI Clock Slave, set it to whatever you have your MIDI Clock Master set as in renoise (master)
After all of that we are ready to start mapping, with the MIDI MAP.
**make sure you save the files now.
Now you can do all kinds of very weird & interesting things from the Renoise (Master)
Open the MIDI MAPPER CTRL + M or apple + M
and select the BPM!!! (Beats / Min.)
You can close MIDI Mapping at this point and see the BPM shifting with the LFO from Renoise(Master)
Now everything you saw high-lighted when you had the MIDI Mapping open, you can control from Renoise (Master)
The true power of Renoise!
