i have reluctantly decided to move from a macintosh platform to a pc platform and because it is macintosh-only software, i am selling my altiverb 5 convolution reverb plug-in. the altiverb 5 plug-in is the latest version and is typically considered the best reverb plug you can buy. it is compatible with the au, mas, vst, rtas and as formats. it sounds amazing. price for altiverb 5: $400 also, the license for altiverb 5 is fully transferable and will be transfered to your name upon purchase. this will enable you to get updates, support and download new impulse responses. if you have any questions or would like to purchase either of these, please email me at lionnelsonmusic@yahoo.com. thanks. lion nelson
