Software I Use
Noteworthy Composer was my first ever computer notation program. It is the one I use the most, because of its ease of use and simplicity. As you can see below, I have other notation programs, but I find myself coming back to Noteworthy Composer.
PGMusic makes two great programs that I use to create recorded music: Band-in-a-Box (BIAB) lets me easily create full band arrangements of songs and RealBand is a simple to use, but very powerful Digital Audio Workstation (DAW) that has many BIAB features built in.
Sonar by Bandlab
After Cakewalk was sold off by Gibson, BandLab bought the rights to the software and rebranded Cakewalk Sonar as Cakewalk BandLab. At least for now, you can get the equivalent of Sonar Platinum for free, and new updates are coming out regularly. A great Digital Audio Workstation (DAW) and you can't beat the price.
Presonus Studio One
Studio One is a great Digital Audio Workstation (DAW) that integrates well with the Presonus notation program Notion (see below).
Notion is a music notation program that lends itself to quick entry and excellent playback within the program. It integrates well with Presonus Studio One (see above).
Harrison MixBus 32C
Harrison MixBus 32C is a Digital Audio Workstation that emulates the world class Harrison console mixer, with built in effects on every fader, minimizing the need for additional VST plugins.
