I use a Roland UM-ONE cable to send receive midi to and from Octatrack MKII. it worked great. After update to 1.7.0 I had the issue with stopping/starting tape transport on OP-1 F from my Octatrack. Transport START doesn’t work. If I start tape transport on OP-1F and hit STOP on Octatrack it stops I downgraded to 1.6.9 and it worked correctly again. Anyone else? Bummer.
