When I wanted to learn notation software I went with Notion. Considering Sibelius and Finale, I was told the playback was better on Notion. I am a hobbyist and time slips away trying to get into my ambitions of learning the software. I play jazz and the sound samples for jazz were not available at the time of purchase. I also bought Progression for guitar. It was simpler to use and I ended up using Progression more. Progression stopped working after OS upgrades. I want to get back into sheet music software and I am at a crossroads to choose one of the other companies and suffer the $700 loss of the monies spent so far with the Notion software. I am guessing Presonus took over the original company that started Notion?? Are there any legacy pricing for original purchasers. I bought a few Presonus products in the past. I am still using the Digimax 8 pre.
