Bassliner is a programmer for the Behringer TD-3 Analog Bass Line Synthesizer.
The app doesn't make sound by itself and is designed to be used with the hardware.
Connect your iOS device to the TD-3 with USB cable and get full access of all patterns on the device. Get a visual view of your patterns and edit them with ease.
You can load, edit and save your edited patterns and hear your changes as you edit when the synthesizer is running.
You will need a USB cable and the Apple Lightning to USB-A or Apple USB-C to USB-A adapter depending on the port of your iPad or iPhone.
