## What is SWAM Double Bass?

SWAM Double Bass for iOS: Unmatched Realism and Expressive Power in Your Hands

Experience the cutting-edge Physical Modeling technology of SWAM Double Bass for iOS, now featuring the revolutionary Room Simulator "Ambiente"! Unlike sampled libraries, this virtual instrument doesn’t play pre-recorded sounds but generates authentic string performances in real-time, responding dynamically to your every nuance, just like a real double bassist.

These instruments are NOT sample libraries. Unlike sampling, which uses recordings to replicate the sound of an instrument, physical modeling doesn’t generate a sound as such but creates the conditions for the system to create it according to an external input (like someone playing on a keyboard). This means every note is unique, and the instrument responds dynamically to your playing style.

With SWAM Double Bass, you can unleash your creativity across any musical style—from classical to modern, film scoring to microtonal music. Whether you're performing live or producing music on the go, SWAM Double Bass is your ultimate companion.

New Features and Key Benefits:
Room Simulator "Ambiente": Take advantage of advanced spatial control with the built-in Room Simulator "Ambiente," which allows you to position the instrument in a realistic acoustic space, interact dynamically with other SWAM instruments in the same virtual room, and create truly immersive performances. Additionally, the legacy Reverb, EQ, and Compressor effects are available for fine-tuning your sound.

Standalone and AUv3 Plugin: Perform in real time or integrate SWAM Double Bass seamlessly into your mobile production workflow.

Intuitive, Inclusive Interface: Designed for everyone, including blind and visually impaired users.

Expressive Control: Play with unmatched expressivity using the exclusive virtual bowing surface, MPE controllers, keyboards, breath controllers, or other MIDI devices.

Top Features at a Glance:
Access a library of presets, create your own, or import presets from the desktop version.
Customize every detail of your sound, including timbre, vibrato, and dynamics.
Micro-tune the instrument with the Pitch Manager, supporting devices like MAQAM for advanced tuning systems.
Add built-in effects like EQ, and Compressor.
Play with different double bass bodies to explore unique tonal variations.
Use AUv3 to integrate with your mobile DAW (Logic, Cubasis, AUM) or apps like Camelot PRO for live performances.
Who is SWAM Double Bass for iOS Designed For?
Wind Controller Players: Looking for a mobile setup to perform live without needing a computer while still achieving an incredible sound.
Keyboard Players: Frustrated by the limited expressive capabilities of normal sample-based plugins? SWAM Double Bass unlocks the full range of expression.
Music Producers: Need a mobile setup to produce music from anywhere without carrying around expensive gear? SWAM Double Bass is the solution.
Musicians Seeking Expressivity: Looking for a virtual instrument that allows you to express the full range of your musicality easily on your iPhone or iPad.

IMPORTANT
To fully harness the expressive power of SWAM Double Bass, a controller capable of continuous expression (such as a breath controller, expression pedal, MPE device, or wind controller) is required. Just like a bow is essential for a real double bassist, SWAM Double Bass needs expressive input for maximum realism.

With SWAM Double Bass for iOS, you have the freedom to create lifelike string performances on your iPhone or iPad. Redefine your music with unparalleled realism and expressive depth—anytime, anywhere.

### 5/5 — Very useful for jazz bass!

*2023-01-23*

I needed a lightweight alternative to Spectrasonics Trilian. While this certainly isn’t up to that level for recording, it’s better than the vast majority of keyboard upright bass samples, and surprisingly playable (after tweaking the sound/ attack). A great alternative to lugging my computer and associated equipment for organ pedal (upright) bass. Just need this and my Apogee Duet for iOS & Mac. I’ll be using this for rehearsals and less intense gigs.

I’m sure it’s useful for the other 95% of what it was developed for (bowing, etc.), I just have no need for it. Only complaint- I wish I could disable the portamento.

### 2/5 — More Like a Keyboard/Synth than a REAL Bass

*2021-11-03*

So….. I bought this to do some jazz, with an upright bass being plucked. I was sooOOooo disappointed. It really sounds more like a keyboard or a synth trying to “emulate” a bass, than a real bass. 

I have some software; Trilian by Spectrasonices that I use as a VST instrument that is absolutely phenomenal!!  But sadly….this software is pretty poor. Especially for the price.

Save your money. You probably have a synth bass patch that will get you about the same sound as this software; without spending extra.

### 5/5 — Walking Bass is phenomenal for jazz & bluegrass

*2021-10-26, version 3.0.3*

Sounds great, works very well when played from my 35 year old midi keyboard w/expression pedal lol 
Sometimes I also play it using my guitar while running it through midi guitar 2, which is very fun to do.

The walking bass setting is amazing, don’t use the bow settings all that much, but they also sound great.

An absolute steal at the price they charge here. A must-have for any garage / bedroom producing hobbyists or for performing live. Throw a little bit of reverb on there and the casual listener would have a hard time telling the difference between this and the real thing - and it sounds so good that even those who can tell the difference would still appreciate it!

Worth every penny
