No, it should not be possible. I was surprised to see a suggestion that people were able to get it to work actually!
Given the method of CV selection, there was a necessary design compromise to be made: though transport and sample modes can’t be paired, you still have some form of FM in either.
If any of you are able to trick the module into pairing transport.THIS/THAT with sampleTHAT/THIS, please do share, but as far as I know it is not possible.
Here’s a workaround if you are looking to have sample.THIS reset actions along with speed control while playing the tape backwards (which you normally would achieve with transport.THAT):
While in LIVE mode, Press PLAY to go to NAV mode and then immediately hold the toggle DOWN and press PLAY to go back to LIVE mode with direction reversed.
You may want to be quick with the gesture as your THAT voltage now sets the tape to a different speed since you are briefly in NAV mode, however this can also be something fun to experiment with. You will also want to be careful about where you choose to execute this action as if you do it near a cue point, you might hit that cue point in NAV mode and redirect according to your THAT voltage; of corse you might intentionally wish to exercise that ability!
A simple solution which doesn’t require going to NAV mode to switch direction is using Teletype to reverse play direction:
WS.PLAY -1/1
