Please note: this is an AUv3 plugin that can be used with compatible host Apps. GS-201 Mark II is the evolution of a project that began in 2007 with the release of the old version of GS-201, which evolved into a mark II version in 2019 and has now landed on the iPad platform. The aim is to capture the magic of the famous Space Echo tape delay and make it available to everyone. It's not an easy task, but the experience gained over the past 15 years in audio DSP development has helped us achieve a result that can sometimes fool even ourselves. This iOS version of the GS-201 Mark II contains only the basic controls found on the original Space Echo, with no additional editing parameters. If you want to eliminate tape hiss, if the tape splice glitch is bothering you, if you don't like wow and flutter, or need host tempo sync, you are definitely looking for a different plug-in. If, on the other hand, you want to relive the experience of dealing with an original Space Echo, with all its pros and cons, you are in the right place.
