I've been doing some low budget demo tracks and I want to improve the sound quality of some of the instruments. I've just been using GarageBand on my iPad and a cheap Casio keyboard for the horn parts. Those horn parts, predictably, sound just awful. After some light research I'm thinking about the Roland Sound Canvas app. It's only $20 so I may just go ahead and try it, but thought I should seek out some opinions first. Is this my best bet? Is there something better at a similar price point? Goal number one is to find a good trumpet sound.
