If you've got a Sequential Circuits Six Trak then you should buy this. This app opens up a whole new way of tweaking parameters and creating patches on the Six Trak. I tried using a lemur template and there's no comparison... this app does so much more. The developer obviously put a lot of love into this app. Buy this app, you won't regret it.

Thank you🤘🏻

This app turned my tedious Sequential Circuits Six Trak to an awesome sound creation workstation. Now I can create new sounds quickly while having fun exploring through the app. I only wish for you to continue upgrading the program and make it even more awesome!
