Okay, here's a better solution for automating Reasons CV trim pots. This example allows panning to be automated in a bipolar fashion as is required whilst still being able to modulate the depth/strength of the CV signal.
- Create a Combinator.
- Create a line mixer inside.
- Assign the Combinators Rotary 1 knob to the line mixers Channel 1 Pan control.
- Label rotary 1 'Pan' or something similar.
-------------------------
- Hold the Shift Key on your keyboard and create a Thor (or disconnect Thors audio output from the line mixer if it is still connected).
- On the modualtion bus routing section of Thor, set the following along the top 'bus' or whatever that thing is called???!! ---> Source: CV In 1 ---> Amount: 100 ---> Destination: CV Out 1 ---> - Amount 100 ---> Scale: CV In 2.
- Route Thors CV Out 1 to the Combinators Rotary 1 Input.
-------------------------
- Create a Malstrom (This can actually be any synth or sampler, but for the sake of this example it is easier if it is a Malstrom.)
- Label the Malstrom 'Noise Source'.
- Route the Malstroms audio output into the Line Mixers channel 1 audio input.
- Initialise the Malstrom to a blank patch (should be a sine wave) and set Oscillator 1 to Square.
- Set the Decay slider on the Malstroms Oscillator 1 section to 127.
-------------------------
- Right click on the Malstrom and create a dedicated sequencer track for it by selecting 'Create Track for [name of Malstrom]'.
- Create a midi clip on the new sequencer track and draw in a long midi note to trigger the Malstrom constantly. (Make the length of the note the length of the entire track or just the length of the loop markers).
- Press play, the Malstrom should be playing an endless constant tone.
-------------------------
- Hold down Shift on your keyboard and create a second Malstrom inside the Combinator and label it 'CV source'. (Disconnect the audio output from the line mixer if it has automatically routed itself.)
- Right click on the Malstrom and create a dedicated sequencer track for this new Malstrom by selecting 'Create Track for [name of Malstrom]'
- As above, we need a long midi note to trigger the 'CV source', so copy the midi clip from the first sequencer track onto the new sequencer track.
- Set the sliders on Oscillator 1 ADSR to Attack: 0 ---> Decay: 127 ---> Sustain: 127 ---> Release: 0
- Set all the sliders on the Filter Env ADSR to 0.
- Route the Mod A output on the back of the Malstrom into the CV 1 Input on the back of the Thor.
- Route the Filter Envelope output on the back of the Malstrom into CV 2 Input on the back of the Thor.
--------------------------
- Expand the Combinators programmer section and select the 'CV Source' Malstrom.
- Assign the Combinators Rotary 2 knob to control the Malstroms Filter Env Sustain control, setting the minimum amount to 31 and leaving the maximum amount on 127. (For some reason I'm at a loss to explain, leaving the min value on 0 doesn't scale the control correctly...)
- Label the Combinators Rotary 2 knob as 'Pan Amount'
In theory, when you play the loop from the beginning, the constant drone from the noise source should be panning left and right equally!
You can use the Mod A section on the Malstrom as the LFO for the pan control.
Rotary 2 on the Combinator modulates the CV level (the amount of LFO signal being sent to the pan control)
You can invert the CV signal being sent from the Mod A section on the Malstrom using the Thor. On Thors modualtion bus routing section, set the left hand 'Amount' level from 100 to -100. Unipolar modulation shapes from Malstroms Mod A section will now track downwards insted of upwards (or left instead of right on the pan control).

Here's a quick dark ambient drone I made using the Combi setup from the last .RSN --->
