Using the Faderport 8 in Studio One 3.x or 4.x (FP8 Studio One mode) it is not possible to individually control the same automation parameters for multiple instrument tracks that are connected to the same instrument instance.
I can understand the logic why this was built as is. S1 assumes there can only be one instrument per track. However, using samplers like Kontakt or Play allow you to load multiple instruments that each listen on different midi channels.
- Create two instrument tracks that both point to the same instance of an instrument, in my example Kontakt 5.
- Make sure the FP8 is in "Edit Plugins" mode.
- Open Kontakt and insert two separate VST's in this Kontakt instance (lets say trumpets and strings), one on midi channel 1, the other on 2, and set those midi channels for track 1 & 2 respectively.
- Using the Faderport 8/FP8 enable "Link" mode, or in S1 enable "Mouse Over" in the recent parameters list; top left corner.
- Enable track automation view, and add the Modulation (from the Midi folder) parameter for both track 1 and 2.
- Select the Modulation parameter for track 1, and touch a fader on the FP8. Assign it to the Modulation parameter by clicking the dark gray triangle (next to the recently used parameter in the top left corner, or hit ALT and M.
If all is configured correctly you can move the chosen fader on the FP8 and the Modulation parameter on this track will adjust accordingly, as well as adding the Modulation in any recorded midi events.
- Now select track 2 and repeat step 6, but use the same fader on the FP8 that was previously used for track 1.
- If you move the fader again, the Modulation parameter on track 2 will adjust accordingly, as expected.
- Now select track 1 again, and move the fader. In this case it still moves the Modulation parameter of track 2, not track 1, causing the wrong instrument in Kontakt 5 to be altered.
In my testing I noticed that the linking of automation parameters is hard coded for the track that was selected at that time. My request is to change this behavior and have the automation applied to the currently selected track (or even better, make this an option), instead of the chosen track that was used at the time (i.e. step 6 above).
This would allow us to fully utilize midi cc to control virtual instruments in our S1 sessions.
A not really usable workaround is to create separate instances of Kontakt (or Play) on each track, but due to hardware constraints this is not practical, or even possible for larger projects.
