Solution:
If you are not getting any sound out of your Toontrack drum sampler in Toontrack Solo, please first make sure that the kit you have chosen loads properly. This can be verified by checking that the samples display is fully loaded in the Drummer’s interface.
Should you receive an error message saying “Failed to Load audio driver”, your computer likely can not find the proper audio drivers to play back through your professional sound card hardware. They may not be installed, or outdated. Check the sound card manufacturer’s website for up-to-date drivers for your exact operating system.
While we recommend you only use Toontrack solo with a sound card designed specifically for audio applications, and shipping with dedicated ASIO drivers, generic ASIO drivers such as those available at http://www.asio4all.com may also help alleviate the problem. Once downloaded and installed, please make sure to choose the ASIO alternative in the Audio Device settings in Toontrack Solo.
