I know we have a few excellent sound decoder installations done by members on Trainboard and I need to know if Soundtrax has a good sound decoder with acceptable motor control for the cordless motor. I have 1FEF with Tsunami with terrible motor control but great sound quality done by me right after the 1st Kato release, 1with Loksound from Kato Kobo shops that`s pretty good but lurches under heavy load and weaker that Tsunami sound output, and one with 1st gen TCS non-sound decoder. It seems like Tsunami is easier set the CVs for me anyway. Don`t have Loksound programming tools/software. Oh please greast swami's enlighten me. PLEASE!
