Cool. I just use the throttle trim now for the same reason, so it doesn't shut off at zero throttle.

I have a switch that puts the sound card channel at about 5% when thrown. This gives me the motor startup sequence without having to move the throttle stick. The throttle channel is mixed to this dedicated channel, though. So as I start to advance the throttle the sound card responds appropriately.

I did it this way because the Mr-RC goes in to an engine "shut down" sequence when the throttle drops to zero. That's fine when you're taxiing back to the pits, but if you're in the air and chop the throttle, the sound card goes through it's shut down sounds and sometimes doesn't "restart" when you throttle up again. When that happens, the rest of the flight is without the sound effects. The dedicated channel with a switch and a mix keeps that from happening. I land and throw the switch back to "off" but the sound card continues to make sound as I taxi. When I get to the pits and chop the throttle completely the card gives me the motor wind-down sequence and my flight is complete!
That is a great idea if you have a spare channel. I did not so I setup my throttle on a three way switch. Down is throttle kill, completely off like a safety switch. Middle position I have set to about 10% throttle, and only 10% throttle no matter what the throttle stick position is. This starts the engine moving at very low rpm as the mrrcsound throttle startup sequence begins. When the sequence is over after a few seconds, I switch the the up position which allows 10-100% throttle. So even if I pull the throttle stick all the way down, it is still idling and I don't get that shutdown sequence and silence when still flying, if I drop the throttle stick too low. After landing and back at pit, I go back to 10% position and then down to throttle kill. Sometimes the shut down starts, sometimes not. So I am now using the down trim while in the "idle" 10% position which will then start the shutdown sequence. Once it starts, I quickly go to throttle kill, and everything is off. That might sound a bit confusing, but seems to do the trick and avoid the dreaded silence when flying!
BTW using a taranis
