The Premier Synth Bass App and 808 Bass Drop App.

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!

I really wanted to like it. I even read the developer’s response to criticism, but friend, the end of EVERY note I play has a loud click where the sample ends. Every Note. All three synths. It’s not useable in any way shape or form. I’d like my money back.

Developer Response ,

Thank you for your feedback. Stay tuned for version 1.5 that will come out later this week. It will include bug fixes for the pop sound and smoother fades for a better pad experience. Let me know via the support link if you have any other suggestions to make this a better app. Thank you!

I was gonna leave a review but idk what to say….. needs a LOT of work……..

Developer Response ,

Perhaps you don’t understand the intent of the app? Or if you have any specific points for how the app isn’t meeting your expectations, that would be great information. IMO the app does exactly what it is expected to do. A low synth bass accompaniment to a band in replacement of a regular bass guitar for specific parts of a song. If you’re using it for a standalone bass tracks app, you’re using the wrong app and didn’t read the description.
