Inspired by the Pultec HLF-3C, the ACM-3SA is a high and low-cut passive filter emulation. The plug-in is available free to download from the Applied Computer Music Technologies website at https://www.acmt.co.uk/products/download-acm-3sa/
V3.1.1 Adds CLAP support for compatible host applications and includes some minor bug fixes backported to the VST2 and VST3 versions.
Note: While every attempt has been made to test the CLAP format plug-in with available host applications, at the time of posting CLAP is still a relatively new and evolving format.
