Ample Bass Upright 3.2.0 for Mac is the current 3.2.0 update build of Ample Sound's upright bass instrument, sometimes shortened to Ample Bass U. It recreates the double bass that underpins jazz, blues, funk and roots music, with the woody resonance and gentle attack that an electric bass simply cannot imitate, making it ideal for walking lines, ballads and acoustic arrangements.

Because an upright is fretless, Ample Sound built a dedicated slide system for this instrument that reproduces smooth legato glides at any speed, pitch or duration. The library was captured with neck, body and room microphones plus a DI signal, so you can blend a natural acoustic image with a more direct, electric-style component. The instrument is a paid Ample Sound licence; owners update through their account, and a trial is offered on the official page.

Key Features

• Upright bass library of 4.26 GB, recorded naturally at every position without destructive processing
• Fretless slide mechanism designed specifically for smooth, realistic upright legato
• Four signal sources — neck, body and room microphones plus DI — with stereo and mono mix modes
• Articulations include sustain, mute, natural harmonic, hammer-on and pull-off, and slides in and out
• AU, VST, VST3, AAX and standalone formats for macOS, ready for Logic Pro, Cubase and Pro Tools

How to Download

1. Download from the official site
2. New users can start with the trial or buy the licence; existing owners sign in to their Ample Sound account to get the 3.2.0 update.
3. Install or update the library on an internal drive or fast SSD, activate online, and rescan the plugin in your DAW.

Is the 3.2.0 update a separate product?
No. It is an update build of the same Ample Bass Upright instrument, not a different library. Your existing licence and account are what you use to download and activate it.

Does it suit non-jazz styles?
Yes. Beyond jazz and blues, the upright tone works well in folk, country, film scoring and singer-songwriter productions anywhere an acoustic, organic low end is wanted.
