The software can't distinguish between right to left even tho there are 2 tracks.Nonetheless, impressive software overall. Looking forward to see your future upgrades.
This issue is now fixed in version 1.2.
The version 1.2 download for Windows is now available from the website: www.visualmusicdesign.com/seemusic
The MacOS and iOS versions still need to be approved by the respective App Store Review teams - will probably be later today or tomorrow.
