Hi,
I did as you suggested, and used Garritan Personal Orchestra 4, and used the three different viola "players" for each staff you have here. It is amazing how good sounds can make the performance even more enjoyable. I really like these three pieces, as well as your other compositions. Your enthusiasm for weaving these instruments' parts together is quite obvious
I'm curious as to whether you play with an ensemble, and are composing for your group, or if you're just enjoying composing for various instruments that you don't play. I do some of both, myself
For example, I'll never be a violinist, but it's fun for me to use violin in some of the backing tracks that I put together. Other times I write up songs that I or my group will use for a performance. It's always interesting to hear what others are doing, as well.
Thanks for sharing your enjoyable pieces with us!
Sherry
