Hi.  I am a previous user of Garritan instruments in Digital Performer on the Mac. Recently I retired. I no longer need all the features of DP, since I am pretty much just doing music for my own enjoyment now. I also migrated from Mac to Windows, because I need to do things more on the cheap these days. I tried running DP 10 on my Windows 10 machine, but the; computer just doesn't have the resources to handle it. It crashes almost immediately. So I am looking for a new sequencing program. I say sequencing because I really don't need to record audio, just do MIDI.  I have been enjoying the current state of playback capabilities in Finale, but I really want a dedicated sequencing program that lets me control more aspects of the sound than Finale allows. I have the latest downloads of the Garritan Anthology (which I love, although Instant Orchestra isn't available in Finale) as well as the UVI sounds that came with Digital Performer. 

What I'm looking for is a MIDI sequencer that lets me utilize all the wonderful control codes in the Garritan libraries, is much less of a memory hog than DP, won't break the bank on my retirement income, and doesn't have the steep learning curve of DP. Don't want much, do I? :)  I have tried to research programs online, but I really need advise from actual users.

Can anyone make a suggestion?

As stated, I am using Windows 10 and current versions of all Garritan libraries.
