Synth Bass Pro is the Premier Synth Bass App to give you the best sounding Low End without the string noise of a standard bass guitar and infinite loop possibilities. Containing Three Iconic synth bass sounds, you are sure to have exactly what you need for many genres of music. Synth Bass Pro is loaded with an 808 "drop" note as well for builds, bridges, and bass drops. Designed to be one size fits all, SBP is preset with three iconic synth bass sounds, rather than customizable settings: - Brown (Soft, Gentile) - Blue (Extra Wide, Deep, and mid-rangy) - Green (Some Grit, yet smooth) How I use Synth Bass Pro: I love using Synth Bass in substitution of a standard bass guitar during certain parts of a song that are lower in volume or dynamics. If a song has a build that goes into a lower chorus, this is what I would use to continue the "emotion" of the song during that chorus, while maintaining the soft chorus feel. Additionally, I love the 808 bass drop feature. Typically I use this feature at the end of a big bridge build and into a big chorus. In my genre, Worship Music, I feel it adds an extra sonic layer that I absolutely love. I recommend using this app with proper sound equipment that can handle lower frequencies and it will sound even better when connected to something that has a subwoofer. I hope you enjoy it!
